Problems solved by technology

[0003] Electric vehicles have high low noise requirements for drive motors, which are often lower than 55db. The connection between the positioning plate of the drive motor and the car body is one of the sources of motor noise. There is a difference between the noise level of the connection part and the number of positioning plates. There is a certain relationship, different motors and car bodies have different matching optimal number of positioning plates. However, there is currently no good test method for determining the optimal number of positioning plates. The number of positioning plates is mainly set by experience, so that As a result, the motor noise cannot be adjusted to the lowest value
