Tips: What is the difference between electric vehicle motors and industrial motors?

1. Strict volume requirements and weight requirements

Ordinary industrial motors do not have such strict requirements for volume size and weight, because industrial sites are huge and generally aim to meet industrial goals first. Electric vehicles are different, the size and weight determine the power performance and driving experience of the vehicle and directly affect the quality of the product. Therefore, the difficulty of electric vehicle motors lies in improving power-weight density and power-volume density. The smaller, lighter and more powerful the motor, the better.

2. Unique torque characteristics

Ultra-high torque is required at start-up or low speed to bring the car speed up to the desired speed in the fastest way. General industrial motors do not have such high starting speed requirement. At the same time, sufficient power needs to be provided at high speed to enable the car to cruise at high speed.

3. Wide speed regulation range

The maximum speed of electric vehicle motor may be 4 times or even higher than the motor base speed. The best solution for electric vehicles today is to eliminate the need for a multi-speed gearbox and use only a fixed gear set. In this case, the wider the speed range of the motor, the better.
