• Always lacking energy when climbing slopes? How to select the appropriate IP67 for hilly courses?

    |

    1. Three major challenges of electric drive motors in hilly terrain

    • Heat load and power loss

    When vehicles travel on hilly terrain, they often need to climb slopes. During the climbing process, the motor continuously outputs high power, causing the equipment to heat up rapidly. When the rate of heat accumulation exceeds the equipment's heat dissipation capacity, the temperature rise will limit the output power. When driving a golf cart, one can clearly feel a decrease in climbing force or a slower acceleration response. Over time, the drive motor will also accelerate insulation aging in a high-temperature environment, affecting the motor's service life. 

     

    • Efficiency loss under low-speed high-torque conditions

    On hilly roads, the motor frequently operates in the low-speed high-torque range. In this condition, the copper loss of the motor is relatively high, and the efficiency is often lower than the steady-state operating point near the rated speed. At the same time, the armature reaction caused by the large current will weaken the air-gap magnetic field, affecting the linearity of torque output. The actual output power of the motor on the slope may differ significantly from that during normal road driving. 

     

    • Frequent starting and stopping as well as variable loads cause wear on bearings and commutator mechanisms

    During hilly driving, with frequent acceleration and deceleration and load changes, the motor shaft is subjected to alternating load impacts, increasing the risk of wear. For brushed DC motors, frequent load variations also accelerate the frictional wear between the brush and the commutator, affecting the reliability of the motor's long-term operation.

     

    2. Core requirements of the electric drive motor for the hilly course

    ① Peak Torque

    The peak torque directly determines the vehicle's climbing ability.

    From a technical perspective, the torque required for a vehicle to climb a slope is jointly determined by factors such as the slope angle, load, and reduction ratio. The maximum slope angle of a typical hilly golf course is usually between 15% and 20%. Combined with the load of the vehicle (2-4 people and golf equipment), a peak torque of over 60 Nm on the 96V platform can meet the needs of most slope scenarios. Higher torque reserves (such as 90 Nm+) are suitable for steeper slopes or greater load requirements. 

     

    ② Rated/ Peak Power

    Peak power determines "whether it can reach the top", while rated power determines "how long it can keep climbing without slowing down".

    The continuous uphill sections on hilly roads may be several hundred meters or even several kilometers long. The motor needs to continuously output a high power. Generally speaking, on the 96V platform, the rated power reaches 6kW, combined with a peak power of 12kW, it can meet the continuous climbing requirements of most hilly golf courses. 

     

    ③ Protection Grade (IP Rating)

    In comparison, the operation of the golf cart on hilly terrain is more demanding on the motor's performance than on flat ground: after rain, there is water accumulation; the slippery road surface left by the irrigation system; the mud and dust carried up by the tires - all these pose higher requirements for the sealing of the motor. 

    IP67 is currently the mainstream protection standard for golf cart motors. It means that the motor can prevent dust and can continue to operate normally even when immersed in water for a short period (1 meter deep, 30 minutes). This level of standard is sufficient to handle the possible water and mud conditions that golf carts may encounter during daily use. Motors below IP67 have a higher failure risk in hilly environments and are not recommended for use. 

     

    ④ Heat Dissipation Design

    During the uphill climbing condition on hilly terrain, the motor operates under a continuous high-load condition, and the accumulation of heat is much faster than during smooth road cruising. If the heat cannot be dissipated in time, the winding temperature will continue to rise, eventually triggering over-temperature protection and even causing irreversible insulation damage. 

    For natural air-cooled motors, the heat dissipation efficiency depends on two factors: the design of the heat dissipation structure and the windward assembly conditions of the entire vehicle. Motor suppliers need to provide clear design concepts in the assembly process, and also assess whether this design can be implemented on the actual vehicle body. Improper assembly will significantly reduce the heat dissipation capacity, even if the motor's parameters meet the standards, the continuous climbing performance will also be affected.

    4. Supplier Evaluation Checklist

    • What are the temperature rise data of the motor during continuous climbing operation?

    This is the most direct basis for evaluating whether the motor can adapt to hilly conditions. A qualified supplier should be able to provide temperature rise data under specific test conditions (slope, load, ambient temperature, duration), rather than just giving a conclusive description. 

     

    • Does the complete torque-speed characteristic curve get provided?

    These characteristic curves can visually reflect the torque output capability of the motor over the entire speed range, and are the fundamental basis for judging the climbing power reserve. For high-torque electric golf cart motors, this curve can clearly show whether the motor has sufficient torque output capability in the low-speed climbing range. 

     

    • Has the protection level reached IP67?

    IP67 is the mainstream standard for mountainous environments. When confirming whether the motor products provided by the supplier meet the IP67-rated club car motor standard, one should request the supplier to provide corresponding test records or certifications as support, rather than merely accepting the markings on the parameter table. 

     

    • Are there clear requirements for windward assembly?

    The cooling effect of natural air-cooled motors is highly dependent on the vehicle installation conditions. The supplier should provide specific requirements such as the direction of the air duct, the windward area, and the avoidance distances of surrounding components. This is the key basis for the purchaser to determine whether the performance of the motor can be fully exerted after installation.

     

    5. Pit Avoidance Guide: Common Mistakes in Motor Selection

    • Misconception 1: The greater the peak torque, the better.

    Peak torque is indeed the most crucial performance indicator for hilly terrains, but it is not necessarily the larger the better. The higher the torque, the greater the current required at the same voltage, and the more severe the heating of the windings will be. If the heat dissipation design cannot keep up, the advantages brought by the high torque will be quickly offset by overheating and reduced power.

    The purchaser should match the torque according to the actual slope and load requirements, and leave an appropriate margin while ensuring it is sufficient. 

     

    • Misconception 2: Ignoring the rated power

    Peak power determines "whether it can reach the top", while the rated power determines "how long it can maintain climbing without slowing down". Many purchasers tend to be impressed by the peak power, but they overlook whether the rated power meets the requirements for continuous climbing on hills. 

    The slopes of the hilly courses are usually not short slopes of just a few dozen meters, but long slopes that stretch for hundreds of meters. Under such conditions, the motor needs to continuously output power. Insufficient rated power will cause the speed to gradually slow down in the second half of the climbing process, and even stop halfway up the slope. 

     

    • Myth 3: Only relying on parameter markings for protection level

    It only takes a few seconds to write "IP67" on the parameter table, but actually achieving this level requires a complete guarantee of the entire process including sealing structure design, process control, and factory inspection. Different suppliers have differences in their understanding and implementation standards of IP67. 

    It is suggested that when selecting the supplier, the specific waterproof and dustproof testing methods and standards should be requested from them, rather than merely accepting the markings on the parameter table. Disassembling and inspecting the sealing structure of the sample is also an effective way to verify the protection capability. 

     

    • Myth 4: Focusing only on the motor, ignoring the matching

    The motor's own parameters meeting the standards is only the first step. The matching between the motor and the entire vehicle in terms of reduction ratio, tire diameter, load capacity, etc. is equally crucial. An excellent motor, if it is matched with an unreasonable reduction ratio, will still perform poorly when climbing slopes.

     

    6.FAQ

    Q1: Is the IP67 protection level really necessary?

    A: Yes, it is. In hilly areas, there is a lot of rain and a lot of dust. The IP67 standard is the minimum requirement to ensure that the motor can operate stably and continuously in an environment with splashing water and mud. 

     

    Q2: Is natural air cooling sufficient?

    A: It is sufficient for light load and short distances. However, for long climbs in hilly areas, it falls under a continuous high-load condition. We need to confirm whether the motor has adequate cooling design to prevent overheating and speed reduction. 

     

    Q3: How can we determine if the existing motor is suitable for hilly terrain?

    A: Three indicators - whether the motor stops halfway during full-load climbing, whether the motor temperature is too high after climbing, and whether there are frequent failures during the rainy season.

  • Brushless control vs. Brushed control How to choose the power system for electric two-wheelers and electric motorcycles?

    |

    With the rapid development of the electric two-wheeler and electric motorcycle markets, users' demands for vehicle performance are constantly increasing, including longer range, faster response, smoother driving experience, and higher system reliability. As an important component of the electric drive power system, the controller plays an extremely crucial role in the operation effect of the entire vehicle and the drive motor.

     

    When choosing between brushed electronic control and brushless electronic control, electric vehicle manufacturers need to comprehensively consider a series of issues such as vehicle application scenarios, speed requirements, power demands, and whether the system can maintain reliability during long-term operation. For modern electric two-wheelers and high-speed electric motorcycles, the brushless electric drive power system is relatively superior to the brushed one in terms of higher efficiency, stronger reliability, and more precise control capabilities. It has gradually become the mainstream choice in the industry.

     

    Understanding the limitations of brushed controllers

    Brushed controllers control brushed motors through mechanical commutation, using brushes and commutators to convert the direction of current. Due to their simple structure and low manufacturing costs, brushed motor systems were widely used in early electric bicycles, low-speed electric vehicles, and basic transportation vehicles.

     

    However, as electric two-wheelers continue to evolve, a large number of vehicle manufacturers are striving for higher speeds, longer ranges, and better driving experiences. The traditional brushed system has gradually revealed certain limitations. Due to the mechanical contact between the brush and the commutator, friction and wear occur, and after long-term use, it may encounter maintenance issues and affect the lifespan of the system, resulting in a significant decline in the overall performance of the vehicle.

     

    At present， compared to modern mainstream control schemes， brushed systems typically have obvious drawbacks in terms of efficiency， power response， and torque control accuracy. For electric motorcycles that require stronger acceleration performance， smoother power output， and stable operation under complex conditions， brushed systems have become difficult to fully meet the operating requirements of modern vehicles.

     

    The advantages of brushless electronic control

    Brushless controllers use electronic commutation technology to replace the traditional mechanical commutation， precisely controlling the current to optimize the management of motor speed， torque output， and energy consumption. Because mechanical losses are reduced， the brushless system achieves higher efficiency， longer lifespan， and smoother power performance.

     

    For electric two-wheelers used for daily commuting， urban travel， and high-speed riding scenarios， the advantages of brushless electronic control are evident. It can provide a smoother acceleration experience， higher energy utilization， and stable performance during climbing， frequent starts， and long-distance riding.

  • How do different types of motor controllers affect the performance of electric motorcycles?

    |

    For electric motorcycle manufacturers, the motor controller is the core of the power system that drives the vehicle and is the central hub for distributing electrical energy throughout the entire vehicle. It serves as a control bridge between the battery and the drive motor, receiving commands from the vehicle controller and the accelerator, and dynamically adjusting the motor current, torque, and speed. All the riding performance indicators, such as vehicle start-up response, high-speed stability, and climbing load performance, are determined by the controller. The selection of the controller scheme directly sets the performance limit of an electric motorcycle product.

     

    one-line communication & CAN2.0 72v controller

     

    For high-speed electric motorcycles targeting a speed range of 100-120 miles per hour, a low internal resistance MOSFET brushless motor controller is a reliable solution. In conditions where continuous high-speed operation is required, the controller must be capable of stable output of large currents and possess excellent temperature control performance.

     

     

    Mainstream Controller Types and Their Basic Characteristics

    Currently, the controller solutions for the electric motorcycle market are diverse, with distinct hardware architectures and functional configurations, and are suitable for different positioning of vehicle projects. The mainstream solutions in the industry are mainly divided into three categories: basic brushless, high-voltage high-current high-performance, and intelligent. Each category has its own applicable scenarios and advantages and disadvantages. 

     

    1. The basic brushless controller without brushes is mainly used in low-speed commuting electric motorcycles. It operates stably in regular constant-speed scenarios. The technology is mature and the failure rate is low, making it suitable for manufacturers who prioritize high cost-effectiveness. 

     

    2. For high-performance high-speed electric motorcycles, high-performance brushless controllers with high voltage and large current are the best choice. Compared with ordinary general-purpose controllers, this type of controller can significantly reduce energy loss under heavy-load conditions, and this type of controller perfectly meets the power requirements of high-speed vehicles.

    For this high-speed electric motorcycle category, we have developed two motor controllers to cover the diverse demands of high-speed models, providing OEMs with application-specific supporting solutions that fit their project requirements.

    Our OTA & UDS supported high-current 72v controller product line covers the complete 48V~72V voltage platform, precisely matching the development requirements for electric motorcycles with a top speed of 100–120 km/h. Low internal resistance MOSFET modules are available as optional accessories, and the controllers are compatible with CAN2.0 communication as well as magnetic encoder signal input.

    Compared with conventional controllers, these two models greatly reduce energy loss under harsh operating conditions. They are unlikely to trigger power derating due to overheating even after prolonged high-speed driving, and are currently supplied stably for mass-produced vehicle models.

     

    3. The intelligent programmable controller is a preferred solution for mid-to-high-end vehicles. Besides basic power control, it also has the expansion capabilities such as integrated Bluetooth debugging and standardized diagnostic protocols. These two controllers from Xiamen Wise not only meet the above high-performance standards but also incorporate support for bluetooth-enabled high-speed motorcycle electrical systems, enabling real-time parameter calibration of the entire vehicle and unified fault diagnosis, fully meeting the differentiated model calibration needs of brand manufacturers.

     

    How the Controller Affects Several Core Performance Parameters of E-Bikes

    As the central control hub for the vehicle's power, the controller has a significant impact on power release, energy distribution, and compatibility with operating conditions. Through concerted efforts in these dimensions, the actual riding performance of the vehicle is redefined. Below, from five core dimensions, we will specifically elaborate on the underlying influence logic of the controller on the overall performance of e-bikes. 

     

    • Starting acceleration and peak torque

    The maximum phase current that the controller allows to output determines the upper limit of the vehicle's instantaneous torque. If the controller has sufficient peak current margin, the vehicle can start smoothly and accelerate rapidly; otherwise, even if the vehicle is equipped with a high-power motor, a conservative current-limiting controller will cause acceleration delays, which will have a significant impact on the riding experience of the end users and is not conducive to the product's market competitiveness. 

    • Continuous high-speed stability

    The controller limits the maximum operating speed of the motor. To achieve continuous high-speed driving at 100-120 feet, a 72V high-voltage controller is the mainstream solution. The low-resistance hardware design effectively suppresses temperature rise, ensuring that the vehicle can maintain its top speed stably and avoiding overheating protection and power drop after a period of high-speed driving, addressing the most common pain points of high-speed vehicles. 

    • Cliff climbing and heavy-load adaptability

    When the vehicle climbs a slope or travels with a full load, the motor requires a large amount of current to support it. This significantly increases the load pressure on the entire vehicle. Ordinary controllers are insufficient in specification and are prone to frequently triggering overcurrent protection. High-specification high-current controllers can maintain stable power output in heavy-load conditions, ensuring the adaptability of the vehicle to complex road conditions and expanding the applicable scenarios of the product. 

    • Vehicle energy consumption and range performance

    The heat loss during the energy conversion process of the controller will directly consume battery power. A controller equipped with low-resistance MOSFETs can reduce heat loss. Under the condition that the motor and battery configuration remain unchanged, optimizing the vehicle's range can help manufacturers optimize the range of their models and enhance the core competitiveness of the vehicles.

     

    • Riding quality and power linearity

    The quality of the riding experience actually hinges on the algorithm of the controller. A high-quality controller provides a smooth and linear power output; while ordinary controllers often have problems such as power fluctuation and delayed throttle response, which can affect the overall quality and brand reputation of the vehicle.

     

    If one wants to select the appropriate controller based on project requirements

    When selecting the prototype for the entire vehicle, it is necessary to align with the product positioning and performance indicators, and prioritize matching the corresponding voltage platform. 

     

    • The 48V controller solution is more suitable for lightweight and low-speed electric two-wheelers for daily commuting purposes, meeting the basic usage needs. The 60V and 72V solutions are specifically designed for 100-120 mph high-speed electric motorcycles, catering to the power output standards of high-performance vehicles. During the selection process, it is necessary to strictly avoid mismatches in the matching of high and low voltage power components, and address the risk issues from the source. 

     

    • The actual usage scenarios of the vehicle model are the core basis for determining the current specifications of the controller. Selecting components as needed can balance performance and cost. For regular commuting and smooth road conditions, electric two-wheelers can choose our 48V-96V 300A Brushless Motor Controller, which can balance power and cost; for high-performance models intended for mountainous terrains, continuous high-speed cruising, and heavy-load starting, sufficient current margin needs to be reserved, and the 48V-72V E-Drive Platform with a mature cooling solution can be selected to ensure stable operation under long-term high-load conditions. 

     

    • Automakers also need to consider the long-term operational capabilities of the products in combination with the project positioning and production planning. Match different production capabilities with research and development projects: For small-batch customized projects, the local parameter debugging function of Bluetooth can effectively shorten the calibration cycle; while for large-scale mass production vehicle projects, controllers that support the UDS diagnostic protocol can achieve rapid fault diagnosis for batch vehicles, reducing the pressure of after-sales maintenance. 

     

    From the perspective of the entire vehicle's lifecycle operation, intelligent controllers with remote update capabilities are the core means for automakers to reduce costs, increase efficiency, and continuously optimize products. The traditional controller update algorithms and parameter adjustments require offline wiring and on-site debugging, which involves a complex process. Controllers with intelligent functions support remote control strategies, eliminating the need for numerous cumbersome procedures, and enabling timely upgrades to the vehicle's safety system.

     

    Based on the above selection criteria, for the 100-120 cm³ high-speed electric motorcycle market, we have launched two motor controllers on the 48V-72V platform, covering different power levels for complete vehicle solutions. The detailed product parameters are as follows:

    FAQ: Common Questions Regarding the Selection and Use of Electric Motorcycle Controllers

    Q1: Is it better for the controller's current specification to be larger? How should the selection be made reasonably?

    It is not necessarily the larger the better. The current specification of the controller needs to be selected based on the actual usage scenarios of the vehicle. For vehicles used for regular commuting and on smooth roads, an intermediate current specification controller can be selected; for high-performance vehicles such as those used for mountainous terrains, continuous high-speed cruising, or heavy-load starting, sufficient current margin should be reserved and a large current controller with mature heat dissipation should be used to avoid triggering overcurrent protection under high-load conditions, ensuring operational stability. 

     

    Q2: What practical value does a controller with OTA function have for car manufacturers?

    The core value lies in cost reduction and efficiency improvement as well as continuous product optimization. Traditional controllers need offline disassembly and debugging to optimize parameters and update algorithms, which is a cumbersome process with high售后 costs； controllers with OTA function can remotely iterate control strategies， eliminating the need for vehicle recalls and enhancing the market competitiveness of the vehicle model. 

     

    Q3: What are the core differences between the basic brushless controller and the high-performance controller?

    The core differences lie in load capacity, heat dissipation performance and scalability. The basic controller is suitable for low-speed commuting and stable uniform-speed operation, but under high-load and long-term high-speed conditions, it has high heat loss, prone to power attenuation, and lacks standardized communication interfaces, resulting in poor scalability; the high-performance high-voltage high-current controller has low overload loss and excellent heat dissipation, supports CAN2.0, UDS diagnostic functions, and is suitable for high-speed and heavy-load scenarios, capable of meeting both mass production and customized requirements. 

     

    Q4: If the controller is improperly selected, what impacts will it have on the entire electric motorcycle?

    It will directly lower the overall performance of the vehicle. It may cause a series of problems, significantly reducing the user's riding experience, even leading to hardware damage. At the same time, it will increase the cost of after-sales maintenance and weaken the market competitiveness of the model.

  • How Does a Permanent Magnet Synchronous Motor Work? PMSM Working Principle Explained

    |

    What is a Permanent Magnet Synchronous Motor (PMSM)?

    With the increasing popularity of electric vehicles (EVs), the market demand for electric drive systems is also growing. As one of the most crucial components in electric vehicles, the motor holds an especially important position in terms of vehicle performance, energy consumption, and driving experience. Among various types of motors, the Permanent Magnet Synchronous Motor (PMSM) has become one of the most widely used motor types in the electric vehicle field due to its high efficiency, strong torque output, and precise control characteristics. 

     

    PMSM is essentially an AC motor. Its most distinctive feature is that permanent magnets are installed inside the rotor, enabling it to generate a constant magnetic field by itself. Unlike induction motors (asynchronous motors), PMSM does not require additional excitation current to create the rotor magnetic field. This characteristic allows for minimizing energy loss and maximizing overall efficiency. 

     

    For modern vehicle applications, the presence of PMSM is not merely about the motor itself. Its integration with intelligent motor control technology is the fundamental guarantee for achieving stable vehicle operation and enhancing energy efficiency.

     

    Basic Structure and Working Principle of PMSM

    2.1 Two Core Components 

    Component Description
    Stator

    Incorporates electromagnetic windings;

    generates a rotating magnetic field when three-phase current is applied.
    Rotor

    Embeds permanent magnets;

    interacts with the stator's rotating magnetic field to produce torque.

     

    2.2 Working Principle

    The working principle of PMSM is based on the interaction between the stator rotating magnetic field and the rotor permanent magnetic field. After the motor controller applies three-phase alternating current to the stator windings, a rotating magnetic field is generated. The permanent magnets on the rotor interact with this rotating magnetic field to produce synchronous torque, converting electrical energy into mechanical energy, which then drives the wheels and enables the vehicle to move forward. 

     

    In actual operation, the motor controller cooperates with the motor to adjust the current direction, frequency and output power in real time according to the driving instructions, ensuring that the PMSM can maintain efficient and stable torque output under different working conditions.

     

    PMSM vs BLDC: In-depth Comparison

    Permanent Magnet Synchronous Motor (PMSM) and Brushless DC Motor (BLDC) are the two most widely used types of permanent magnet motors at present. Both use permanent magnets, but they differ in control methods, performance, and application scenarios. 

     

    Overall Comparison：

     

    Comparison Dimension PMSM (Permanent Magnet Synchronous Motor) BLDC (Brushless DC Motor)
    Control Waveform Sinusoidal Current Trapezoidal Current
    Torque Smoothness Smooth, Low Torque Ripple Relatively High Torque Ripple
    Operating Noise Low Relatively High
    Control Complexity More Complex (Field-Oriented Control / FOC) Simpler (6-Step Commutation)
    Cost Higher Lower
    Efficiency 93-95% Peak Efficiency, with advantages in average efficiency under all operating conditions Slightly lower average efficiency under all operating conditions compared to PMSM
    Typical Applications Electric Vehicle Main Drive, Industrial Automation Cooling Fans, Power Tools

     

    Key Differences

    The most fundamental difference between the two lies in the control method. PMSM uses sinusoidal wave current drive and is combined with vector control (FOC, which is field-oriented control), enabling independent regulation of flux and torque, and having good dynamic response. BLDC, on the other hand, uses trapezoidal wave current and six-step commutation control. Although it has a simple structure and low cost, it becomes limited in scenarios requiring high precision or high rotational speed. 

     

    When it comes to actual performance, the differences are also quite obvious. Due to the sinusoidal wave drive, PMSM offers smooth torque output and low operating noise, which is precisely why PMSM has become the dominant technology in the passenger vehicle sector.

     

    Application of PMSM in Electric Vehicles

  • What Are the Core Motor Vendor Evaluation Criteria for Automotive OEM Manufacturers?

    |

    With the rapid iterative upgrading of new energy vehicles, intelligent driving, and vehicle electrification, high power density permanent magnet synchronous motors, as the core components of the drive system, have become the key core components that determine the power performance, driving safety, and durability of the entire vehicle. Selecting reliable and compliant automotive-grade automotive electric motor suppliers has a direct impact on the quality of the entire vehicle, the production delivery capability, and the market reputation of the OEM. 

     

    In the current market, the qualifications of automotive component suppliers vary greatly. Most original equipment manufacturers (OEMs) are unable to meet the standardized and comprehensive supplier evaluation standards. This will lead to problems such as inconsistent performance, delayed delivery, failure to meet vehicle-grade certification requirements, and insufficient R&D capabilities in mass-produced products, thereby restricting the mass production of vehicles and the upgrade of quality. 

     

    This text will comprehensively outline the standardized evaluation criteria for motor suppliers, providing direct and applicable selection and procurement guidelines for vehicle manufacturers and distributors.

    1.The necessity of strictly selecting motor suppliers

    1. Meeting the safety and quality compliance requirements of vehicle regulations

    The core motors in automobiles are key safety components of the entire vehicle, and must comply with authoritative certification standards in the automotive industry such as IATF16949. System certification can effectively avoid potential hazards caused by poor motor quality. 

     

    2. Ensure stability of the mass production supply chain

    Automobile manufacturers have large-scale production demands. High-quality suppliers need to have stable production capacity, standardized process management, and risk emergency mechanisms. This can effectively prevent major losses such as vehicle production halts and order delays caused by insufficient supply and delayed delivery. 

     

    3. Adapt to the long-term research and development, iteration and upgrading of the entire vehicle

    The vehicle models of car manufacturers are continuously updated every year. High-quality motor suppliers can cooperate with the vehicle manufacturers to conduct simultaneous research and customization to optimize product performance, adapting to the technological upgrading needs of new energy and intelligent vehicles, and achieving long-term technical collaborative upgrading. 

     

    4. Achieve full life cycle cost control

    A scientific supplier evaluation system can balance the upfront procurement costs with the subsequent maintenance, fault replacement, and after-sales operation costs, preventing the overall cost increase throughout the entire chain caused by using low-price and low-quality suppliers, and achieving the dual benefits of cost reduction and quality improvement.

     

    2.Core assessment criteria

    1. Compliance qualification certification

    Compliance qualification is the hard entry standard for automotive OEMs to select core motor suppliers. It directly determines whether the products meet the compliance requirements for vehicle mass production. Qualified motor suppliers must possess IATF16949 automotive quality system certification, ISO9001 quality management certification, and a complete set of vehicle-grade product safety certifications. They must also have formal vehicle assembly qualification and mature cooperation projects with vehicle manufacturers. The OEMs need to conduct risk screening in advance to avoid suppliers with major quality accidents, supply contract breaches, or industry bad records, thus establishing a solid compliance foundation for the supply chain from the source. 

     

    2. Technical and Performance Verification

    Technical strength and product performance are the core key indicators for evaluating motor suppliers, directly influencing the power performance, safety, and durability of the entire vehicle. High-quality suppliers must have an independent R&D team, stable R&D investment, and reserves of core patents for automotive motors to ensure continuous technological advancement. Production-grade automotive motors must have high power density, high energy efficiency, low noise, excellent heat dissipation, and long service life, and be able to stably adapt to extreme driving conditions such as high and low temperatures and complex road conditions. At the same time, suppliers must support customized parameters for specific vehicle models and synchronous R&D iterations to align with the update rhythm of the vehicle manufacturers' models. 

     

    3. Production Capacity and Quality Control System

    A mature production scale and standardized quality control system are the core guarantees for the mass production of the main vehicle manufacturers. Reliable partner companies should be equipped with production lines and production areas, capable of stably handling large-scale orders. Relying on the full-chain quality inspection during the product's final factory inspection, it effectively ensures consistent performance of batch products and stable product qualification rates, significantly reduces quality fluctuations of mass-produced products, eliminates the common problem of inconsistent quality between samples and products in the industry, and continuously delivers stable and reliable automotive-grade motor products. 

     

    4. Supply Chain and Delivery Capacity

    A stable supply chain and efficient delivery capabilities are the key operational supports that ensure the production rhythm of the vehicle manufacturers and avoid the risk of production halt. The high-efficiency EV motor suppliers for new energy vehicles have a stable raw material supply chain and regular inventory reserves. They can clearly define the standard delivery cycles for both regular and customized products, maintaining a high rate of on-time delivery. At the same time, they are equipped with emergency production capacity plans during peak seasons to effectively handle sudden situations such as surging orders and fluctuations in raw materials. Combined with professional auto parts protective packaging and a full-process traceability logistics system, they can maximize the guarantee of the integrity and on-time delivery of large quantities of goods, ensuring that the production progress of the vehicle manufacturers is not affected.

  • What are the differences among the motor controllers designed by different manufacturers for electric two-wheel vehicles?

    |

     

    48v - 96v Electric Two-wheeler Motor Controller (60 - 80 Miles)

    How different are the motor controllers of electric two-wheelers designed by different manufacturers?

     

    The answer is not found in the parameter tables, but lies in each rider's riding experience.

     

    I. The True Manifestation of Differences

    As the electric two-wheeler market continues to grow globally, the motor controller has become one of the key components that significantly affect the overall performance, efficiency, reliability, and driving experience of the vehicle. 

     

    Many users will find that even if two motor controllers are marked with the same voltage, current and power parameters, their actual performance when installed in a vehicle can be completely different. Some controllers offer smooth starting, strong acceleration, low temperature rise, and can operate stably for a long time; while others, although their parameters seem the same, may encounter problems such as insufficient power, sluggish response, severe motor overheating, low efficiency, and even high failure rates. 

     

    II. Why the actual performance differs under the same parameters

    Parameters are merely the basic specifications of the hardware, but the actual performance of the controller is determined by the design of the entire system. 

     

    The definition of current output capability varies. For example, when labeled with a peak current of 100A, some manufacturers specify it as "continuous stable output", while others specify it as "instantaneous peak". Additionally, due to differences in heat dissipation design and temperature protection strategies, some controllers can output a large current for a long time, while others can only maintain this high current for a few seconds before reducing power. 

     

    The levels of control algorithms vary. The controller determines how much power the motor should output through software algorithms. Algorithms that are excellent result in smooth starting, quick response, and high efficiency; while algorithms that are rough lead to jerky starting, low-speed jitter, high-speed power loss, and high energy consumption. With the same hardware configuration, different software adjustments can result in a difference of several levels in the actual riding experience. 

     

    Therefore, a truly outstanding controller is a combination of hardware capabilities and software algorithms. Below, we will specifically analyze the design differences among different manufacturers from three dimensions: algorithms, power devices, and heat dissipation reliability.

     

    To determine whether a motor controller is excellent, one cannot merely rely on the product parameter table. Instead, a comprehensive assessment of the following aspects is required: 

     

    III. Control Algorithm: Determining the Driving Experience of Electric Vehicles

    In the design of the motor controller, the control algorithm is a crucial factor influencing the driving experience of the vehicle. 

     

    In the early days, electric two-wheelers mostly adopted the traditional BLDC control method. This approach was mature in technology and had low costs, which could meet the driving needs of basic electric vehicles. However, as the market's demands for high-speed performance and driving experience increased, the traditional control method gradually revealed some limitations:

    - Insufficient smoothness at low speeds;

    - Obvious noise from the motor;

    - There is still room for improvement in energy conversion efficiency. 

     

    Therefore, an increasing number of mid-to-high-end electric vehicles are adopting FOC (Field-Oriented Control) technology. FOC achieves more efficient and smoother power output by precisely controlling the motor's magnetic field. Compared to traditional control methods, FOC controllers typically have:

    - Better low-speed torque performance;

    - Faster power response;

    - Lower operating noise;

    - Higher energy efficiency. 

     

    For applications involving 60-80 cm two-wheelers and three-wheelers, since these vehicles need to balance both starting power and high-speed stability, the controller not only needs to output sufficient current, but also requires excellent software tuning capabilities. 

     

    In actual development, a controller suitable for the 48V-96V pure electric platform usually requires parameter optimization based on different motor types, vehicle weight, and usage environment, including:

    Parameter Effect
    Peak Phase Current Control Determines acceleration performance and peak power output
    Field Weakening Control Affects high-speed operation capability
    Torque Response Curve Influences ride smoothness and drivability
    Regenerative Braking / Energy Recovery Strategy  Impacts range performance

     

    With the same hardware specifications, the software tuning capabilities of different manufacturers often result in significant performance differences.

     

    IV. Power Device Design: Determines the Output Capacity and Reliability of the Controller 

    Apart from the software algorithms, the hardware design also determines the performance of the controller.

    The core components include:

    - MOSFET power module;

    - drive circuit;

    - current sampling module;

    - main control chip;

    - filtering and protection components. 

     

    Proper manufacturing companies will adopt more reasonable power module designs and select different current level schemes according to application requirements：

    Application Scenario Typical Requirements Controller Design Focus
    Two-Wheeler High-speed power delivery, fast dynamic response  Peak current capability, precision control
    Three-Wheeler Heavy load capacity, continuous operation High reliability, sustained output capability

     

    For the application of 60-80 km/h electric two-wheelers and three-wheelers, the 48V-96V pure electric controller platform developed by WISEDRIVEPOWER supports the configuration selection of MOSFET modules, and can be matched according to the power requirements of different vehicle models. 

     

    This platform supports CAN communication and can handle a wide voltage range from 48V to 96V. It offers a 300A high current brushless motor controller 48v with a peak current output capability of  level. As a 48V-96V CAN-enabled custom motor controller, it can be flexibly customized at both the hardware and software levels according to customer requirements, and is suitable for various applications in light electric vehicles.

     

     

    V. Heat Dissipation and Reliability Design: Determining the Long-Term Performance of the Controller

    During the operation of the motor controller, a significant amount of heat is generated, especially when a large current is being output. 

     

    If the heat dissipation design is inadequate, even if the performance meets the requirements for a short period of time, after long-term operation, the following issues may occur:

    1.Decrease in power

    2.Temperature protection

    3.Shortened lifespan of components

    4.Reduced system stability

     

    Therefore, excellent controllers usually optimize heat dissipation from both the structural and material aspects. For example:

    - Use a high-conductivity aluminum alloy casing;

    - Optimize the layout of internal power components;

    - Enhance the natural cooling effect;

    - Design the heat dissipation path according to the vehicle installation position.

    For electric vehicle applications, lightweighting and heat dissipation capabilities are equally important. 

     

    The 48V-96V electric vehicle control platform of WISEDRIVEPOWER adopts a lightweight magnesium alloy motor controller design. This design not only reduces the overall vehicle weight but also takes into account structural strength and heat dissipation requirements, making it more suitable for vehicles with specific weight and performance requirements.

     

    VI. How to Select an Appropriate Motor Controller Supplier

    For electric vehicle manufacturers, choosing a motor controller supplier is not simply a matter of comparing prices or parameter tables. Instead, it should involve a comprehensive assessment of the supplier's R&D capabilities, product reliability, customization ability, and long-term cooperation capacity.

     

    A truly outstanding motor controller supplier can provide customers with support throughout the entire process from product design, performance optimization to mass production, offering stable, efficient and reliable electric drive solutions for the entire vehicle enterprise. 

     

    VII. Frequently Asked Questions (FAQ)

    Q1: What are the fundamental differences between motor controllers designed by different manufacturers?

    The core differences lie in the precision of the control algorithm, the selection of power components, and the heat dissipation design. The parameter table only indicates the upper limit; the actual riding performance is what matters most. 

     

    Q2: How can one quickly determine the reliability and production consistency of controllers from different manufacturers?

    The reliability differences mainly stem from component quality, heat dissipation structure, and environmental testing standards. Quality manufacturers will conduct factory tests such as high-temperature aging, vibration, and waterproofing, and strictly control production consistency. It is recommended to visit the factory in person, request third-party inspection reports, and verify the actual performance by testing the sample vehicles.

  • What kind of electric drive system can be considered "good"?

    |

    After working in the motor drive industry for many years, I often heard customers ask: What are the advantages of your products?

     

    Compared with simply listing the product parameters before, my current understanding is: A good electric drive system is not determined by how excellent a certain indicator is, but by whether it can help customers avoid those "invisible troubles".

     

    In my opinion, a good electric drive system should have five dimensions.

    Firstly, the authenticity of working condition efficiency.

    Usually, there is a gap between the test data and the actual working conditions. Many suppliers' efficiency data is based on theoretical values under ideal conditions, and this gap will become apparent after the actual installation. What we can guarantee is that each product will undergo comprehensive testing before leaving the factory, covering different rotational speeds and torque ranges, to ensure that the equipment is verified and operates normally before delivery.

     

    On this basis, we collaborate with universities to conduct basic research, conducting complete efficiency mapping tests for different loads and rotational speed ranges. Customers can obtain corresponding measured data based on their own application scenarios, rather than generalized theoretical values.

     

    Secondly, it is system compatibility.

    The compatibility of the motor and the controller determines the final performance of the vehicle. If the parameter coupling between these two units is not fully handled during the design stage, it may lead to efficiency loss and even trigger system protection mechanisms and test suspensions. The difficulty of matching lies in it involves the dynamic coordination between the two units, and cannot be simply solved by considering only one side's parameters.

     

    Our approach is to explicitly calculate this coupling relationship during the design stage. Since our product matrix encompasses two product lines: self-developed full-range permanent magnet synchronous motors and controllers, we have a clearer understanding of the chain reaction that an improper interface could cause to the entire vehicle. Regardless of whether the customer chooses to have the entire system delivered or to purchase it themselves, we will provide complete matching parameter support and offer sufficient guidance to ensure that the system can operate at its best after delivery.

     

    Third, the traceability of reliability.

    For automotive products, reliability is of utmost importance. Our approach is to establish a comprehensive process data traceability system, documenting every aspect from raw material batches, assembly parameters to factory test results. Whenever the purchaser needs to review these data, they can do so at any time. The value of this system lies in its ability to quickly identify problems when they arise and reassure customers when no issues occur.

     

    Fourth, adaptability to different situations.

    Different vehicle models and different working conditions have significantly different requirements for the electric drive system.

     

    This is why our product line includes corresponding product platforms ranging from 48V to 540V, and the product types are applicable to various fields such as micro vehicles, off-road machinery, low-altitude aircraft, and electric two-wheeled and three-wheeled vehicles. The powertrain for micro vehicles offers two pure electric platforms of 96V and 320V for selection; in the off-road and commercial vehicle fields (covering from micro commercial vehicles to heavy-duty electric truck motor controllers), there are extended-range and pure electric platforms of 320V and 540V, as well as a two-in-one generator controller solution; the power platform for two-wheeled and three-wheeled vehicles covers 48V to 96V, corresponding to different speed requirements of 60-120 feet. We have planned the product line in this way to help customers find suitable solutions for different projects without having to repeatedly contact suppliers or complete certification processes.

     

    At the same time, we also support customized development. For customers with special application requirements, the R&D team can conduct specialized development based on specific voltages and powers. Standard products cover most application scenarios, while customized solutions meet specific needs. The combination of the two ensures that various needs of customers in different projects can be met.

     

    Fifth, a complete service cycle.

    This might be the aspect that is most easily underestimated. We are not only product manufacturers, but also suppliers capable of providing complete motor & control solutions for each project, covering selection, on-site technical support, and after-sales response. When customers encounter problems, our team can provide substantive assistance and solutions at different stages.

     

    • Selection stage → Recommend the optimal solution based on the customer's working conditions and provide measured efficiency data to support the decision-making.
    • Development stage → Match parameters delivery, communication protocol integration, and prototype debugging support.
    • Mass production stage → Stable batch delivery and standardized quality control.
    • After-sales stage → Rapid response mechanism, remote or on-site support from the technical team.

     

    The customer ultimately chose not just the hardware, but also a feasible solution and a reliable partner that can ensure implementation.

     

    The hardware parameters are the foundation. What truly matters is the profound understanding of the application scenario, the control ability for system matching, and the willingness to execute the delivery and service.

  • What Should OEMs Focus On When Selecting Suppliers For Vehicle Electrification And Powertrain Technologies?

    |

    As the process of vehicle electrification continues to accelerate, vehicle OEMs will face many crucial choices when selecting powertrain technology suppliers. Choosing the right technical partner will directly affect product competitiveness, project progress, and the iterative capabilities of the product in the later stages. Therefore, the procurement teams of vehicle manufacturers need to establish a complete evaluation system.

     

    Technical platform capabilities

    Electric drive power systems with different power and voltage levels

    The first step for OEMs when selecting automotive component manufacturers is to assess the product layout matrix of the supplier, which can reflect the product coverage and development strength of the supplier. Mature suppliers will build modular electric drive product platforms, create matrices of electric drive systems with different power and voltage, and adapt to diverse application scenarios.

     

    Here is a reference for our multi-scenario power platform:

    Product Platform Classification Covered Voltage Range Typical Application Scenarios Core Product Composition
    Micro-Vehicle Powertrain System 96V / 320V Low-Speed Micro-Vehicles Flat-Winding Motor + Controller Complete System
    Off-Highway & Commercial Vehicle Propulsion Platform 320V / 540V Construction Machinery, Commercial Special-Purpose Vehicles Extended-Range / Pure-Electric Controller, 2-In-1 Generator-Drive Unit
    Low-Altitude Propulsion Platform 450-750V Low-Altitude Aircraft 2-In-1 Generator-Controller Unit
    E-2/3-Wheeler & E-Motorcycle Platform 48-96V E-Motorcycles, 2-/3-Wheel Mobility Vehicles Motor Controllers of Various Power Ratings
    DCDC Converter 48V to 320V Vehicle OnBoard Voltage Conversion Mountable DCDC Controller

    Based on this, it is necessary to conduct further verification of the R&D technical level. This is crucial for ensuring the rapid adaptation and iterative upgrading of electric drive products and the vehicle project in the future.

     

    Match platform customization development requirements

    Automotive manufacturers need to assess the development capabilities of suppliers in adapting to different vehicle platforms. A large number of projects in the industry have a hard requirement for customization development. For OEMs, suppliers that have both the ability to deliver mature standard products and custom motor & control solutions have greater cooperative value.

     

    By adopting the "standard products + on-demand customization" model and coordinating efficiently in engineering, risks in vehicle integration can be avoided in the early stage of the project, and the cost of later modifications can be reduced. This is particularly crucial for special vehicles and medium-low voltage platform projects.

     

    Quality control

    Complete factory inspection is the first barrier to assess the reliability of a product. As an OEM, it is necessary to verify the supplier's capabilities. The following three types of tests should be given special attention:

    1. Bench testing: Conducting rated / peak condition tests on the entire electric drive system to verify core indicators such as power, torque, system efficiency, temperature rise, NVH (noise, vibration, and harshness) noise and vibration, ensuring that the actual output is consistent with the parameters specified in the specification;

    2. Durability and reliability testing: Testing whether it can complete continuous condition durability and alternating load shock tests to verify the stability of the motor and controller during continuous operation, avoiding the risk of fatigue failure;

    3. Environmental adaptability testing: Covering high and low temperature cycles, temperature variations, and humid heat environmental tests, simulating extreme usage scenarios such as extreme cold and heat, to confirm that the entire machine can operate stably in different environments.

    All tests should retain complete and traceable test reports. Rejecting solutions that rely solely on theoretical simulation without real measurement verification.

     

    Industry and overseas market certifications

     

    The system certifications that the supplier possesses in the industry are also particularly crucial. For electric drive system manufacturers in the automotive component manufacturing industry, the IATF16949 automotive quality management system is the basic entry threshold, representing that the enterprise has standardized automotive component design, manufacturing, and quality control capabilities. For overseas markets, CE certification is an important entry qualification for product exports to regions such as the European Union. OEMs need to combine their target markets to confirm the overseas product qualifications of the suppliers.

     

    Verify the capability for mass production

     

    At present, there is a market pain point in the industry: although the prototype of the product performs well, it cannot smoothly transition to mass production. OEMs should focus on checking whether the suppliers can deliver production-ready electric drive systems. Verify the vehicle-grade verification, complete test reports, and the process control level at the production site to ensure the quality consistency between the prototype and the batch products. At the same time, assess the supplier's existing production capacity and expansion capabilities, as this is related to whether the later equipment for components can keep up with the supply requirements after the vehicle is launched.

     

    Collaborative R&D technical capability

     

    A high-quality and qualified supplier not only needs to deliver hardware prototypes but also needs to deeply participate in the entire vehicle development process. In the early stage of the project, they should cooperate to complete vehicle system simulation and indicator matching, outputing dynamic models that can be used for vehicle simulation; during the development stage, provide bench testing, real vehicle calibration services, and complete torque strategy, braking energy recovery, and thermal protection logic tuning; and simultaneously output complete engineering documents such as CAN matrices, UDS diagnostic specifications, fault libraries, and mechanical and electrical drawings to support vehicle integration, certification, and subsequent after-sales maintenance work.

     

    Weigh the value of long-term partners

    When OEM conducts supplier evaluations, they need to comprehensively consider the customized development capabilities, mass production maturity, system performance, and long-term cooperation potential. High-quality suppliers not only need to create a suitable high-performance electric vehicle powertrain, but also need to have the ability to provide technical services throughout the entire vehicle development cycle. Both parties maintain the same technical approach, along with timely and efficient technical support, to jointly promote the iteration and market implementation of the vehicle project.

  • Essential Maintenance Guide for Isuzu Truck Mounted Cranes

    |

    Isuzu truck mounted cranes are widely used in construction, logistics, power engineering, and municipal projects. Proper maintenance not only improves operational safety but also reduces downtime and operating costs. Based on years of industry experience, crane maintenance can be divided into three basic categories: routine maintenance, preventive maintenance, and corrective maintenance.

     

    Isuzu Truck Mounted Cranes

     

    1. Routine Maintenance: Daily Inspections Prevent Major Problems

    Routine maintenance should be carried out before and after daily operations. Operators should inspect the hydraulic oil level, wire ropes, hooks, outriggers, and control systems to ensure that all components are functioning properly.

    One of our customers in West Asia noticed that the boom of a 5-ton Isuzu truck mounted crane was moving more slowly after several months of operation. During a routine inspection, technicians discovered that the hydraulic oil level had fallen below the recommended range due to a minor hose leak. After replacing the damaged hose and refilling the hydraulic oil, the crane returned to normal operation.

    This case demonstrates how simple daily inspections can prevent larger hydraulic system failures and costly downtime.

    2. Preventive Maintenance: Scheduled Servicing Ensures Long-Term Reliability

    Preventive maintenance involves servicing the crane at regular intervals based on operating hours. Key tasks include replacing hydraulic filters, inspecting cylinder seals, tightening structural bolts, lubricating moving parts, and checking the boom structure.

    A logistics company in South America operates an Isuzu NPR truck equipped with a 6.3-ton knuckle boom crane and performs preventive maintenance every 500 operating hours. During one scheduled inspection, technicians discovered excessive wear on the slewing bearing. The bearing was replaced before failure occurred, preventing potential damage to the crane's rotation system and avoiding several days of operational downtime.

    Regular preventive maintenance helps operators identify potential issues before they develop into serious mechanical failures.

    3. Corrective Maintenance: Prompt Repairs Keep Projects on Schedule

    Corrective maintenance is required whenever equipment malfunctions occur. Common issues include hydraulic leaks, boom extension problems, electrical faults, and abnormal crane rotation.

    One of our customers in Africa experienced difficulty fully extending the boom of an Isuzu truck mounted crane while lifting a load on a construction site. After troubleshooting, technicians found that worn hydraulic cylinder seals were causing internal pressure loss. The seals were replaced, and the hydraulic system was tested. As a result, the crane regained its full lifting performance.

    Timely corrective maintenance prevented further damage to the hydraulic cylinders and minimized project delays.

    Routine maintenance, preventive maintenance, and corrective maintenance are all essential for maximizing the performance and service life of an Isuzu truck mounted crane. Daily inspections help identify visible issues, scheduled servicing prevents unexpected failures, and timely repairs restore equipment to peak operating condition. Companies that follow a comprehensive maintenance strategy can improve safety, reduce operating costs, and achieve higher equipment utilization rates.
