As for automotive motors, the space for motors is subject to many restrictions due to the overall requirements of vehicle body space and performance improvement. Therefore, the overall matching with the vehicle body can only be achieved by maximizing the power density of the motor. The power density of automotive motors is currently at the level of 3.5-4kW/kg. With the popularization of new energy vehicles and the continuous improvement of motor technology, this indicator is expected to increase further. For this reason, automotive motors are very particular about design and materials. For example, in terms of the selection of electromagnetic wires, improvement of winding types, control of motor core materials, and selection of permanent magnet materials, the requirements are higher than those of ordinary industrial motors, especially for the higher endurance requirements of electric vehicles, which puts forward higher satisfaction requirements for matching motors.

 

Therefore, due to the different application characteristics of automotive motors and ordinary industrial motors, there will be a large difference in the requirements for volume.
