Modal Analysis and Structure Optimization of Permanent Magnet Synchronous Motor

Permanent magnet synchronous motors are the core components of electric vehicles and widely used in the field of electric vehicles. The existence of vibration will reduce the operating efficiency and service life of the motor, which is the key factor to determine whether the motor is running normall...
