What to Look for in a Motor Manufacturer A Beginner’s Guide for Procurement Teams
Selecting the right motor manufacturer is one of the most crucial decisions that the entire vehicle manufacturing team needs to make during the procurement process. The motor is the heart of an electric vehicle, and a wrong choice could lead to a sharp increase in subsequent production costs, as well as potential quality issues with the vehicle and disruptions in the supply chain. For teams that are new to purchasing electric vehicle components, this area can be overwhelming. Don't worry, this article will break down the key selection evaluation criteria for you, helping you make a wise and accurate decision.
Specifying Motor Needs for EV
Before starting to collect motor suppliers, the most important task is to clearly determine what type of motor your vehicle platform actually requires. What voltage and power range does your system need? What are your torque and speed specifications? What are your requirements for the cooling method?
Any choice must be based on the requirements of your vehicle. Avoid situations where a motor that performs well in one application may not be applicable at all in another.
However, a high-quality New Energy Vehicle High Power Brushless Motor Manufacturer usually offers a diversified range of vehicle platforms - from micro vehicles, tricycles to construction machinery.
Assessing Motor Manufacturer Quality Control
After initially selecting a group of potential partners, the next step is to conduct a thorough investigation into their quality inspection capabilities. For a mature motor manufacturer, the following should be included:
Cleanroom: Control the impact of dust particles and humidity on the insulation of windings and the assembly of bearings.
Human-operated production line: Key processes must be operated by certified technicians and strict self-inspection and mutual inspection records must be followed.
Testing and verification equipment: Do they have bench testing equipment, thermal cycling test chambers, and insulation resistance testers?
Quality certification: IATF 16949 (quality management system for the automotive industry, emphasizing zero defects and process control) and CE certification, etc.
Factory inspection: Conduct tests at all levels and throughout the entire series to ensure that each product is traceable.
Manufacturers with a complete quality control system will bring lower defect rates, better traceability, and faster problem-solving capabilities to the entire vehicle equipment. These conditions can guarantee your subsequent production progress.
The Product Line of the Motor Category Covers
As a high-quality motor manufacturer, the product line must include PMSM motors as the core category to meet the strict requirements of various application scenarios for electric drive systems. Permanent magnet synchronous motors (PMSM) have become the mainstream choice for electric vehicle motors due to their high efficiency, high power density, and excellent low-speed torque characteristics.
WISEDRV closely follows industry trends and has launched permanent magnet synchronous motors that adopt the flat wire (hairpin) winding process. Compared to traditional round wire motors, the flat wire winding increases the stator slot fill rate from approximately 40% to over 70%, and the copper filling volume is also enhanced. If you are curious about why this technology is used, here is the answer:
Higher power density: The same volume can carry more current and output higher power, achieving lightweighting of the system
Better heat dissipation performance: The contact area between the flat wire and the stator slot is larger, and heat conduction is more efficient, effectively reducing temperature rise and extending the motor lifespan
Better NVH performance: Runs more quietly and smoothly, enhancing the driving and riding comfort
If your application scenario requires the motor to have high starting torque to handle climbing or heavy-load acceleration, then the WISEDRV High Torque PMSM Electric Motor is the ideal choice. This motor performs exceptionally well in low-speed high-torque scenarios, while maintaining high efficiency over a wide operating range, providing a significantly smoother and more comfortable driving experience. WISEDRV has developed and launched efficient, precisely controlled, and durable motor products and solutions, helping various partners achieve performance breakthroughs in demanding application scenarios. Currently, multiple projects have been completed.
Supply Chain for Car-Mounted Motor
Manufacturers whose products meet quality standards but fail to deliver on time are of no help either.
During the in-depth decision-making stage, you need to list the following key questions:
Delivery cycle: How long is the current production delivery cycle? How do they handle urgent orders?
Capacity: Can they increase their capacity as your production volume expands?
Output: Does it support batch delivery?
For vehicle platforms that require on-board integration, you should choose manufacturers that offer Car-mounted high-power brushless motor solutions. These motors are designed specifically for the vibration, thermal cycling and space constraints of the automotive environment.
