This paper takes the order noise problem of permanent magnet synchronous motor as the research object, the motor torque ripple and vibration response are evaluated, and whine is confirmed that caused by the excessive harmonic tangential Electromagnetic force. Taking the design parameters such as magnet arrangement and rotor auxiliary slot as the independent variables, reducing the motor torque ripple as goal, by setting up the motor optimization simulation process, establishing high-precision mathematical response surface to simulate motor physical model, finally obtaining the optimal parameter values under the premise of ensuring that the output characteristics are not reduced. The simulation verifies the structural design with excellent NVH performance, this optimization study can effectively improve NVH performance, which is guiding significance for the forward development of the motor.
