Abstract: NVH simulation analysis can predict the electromagnetic vibration noise characteristics of a motor in the design stage,so as to propose the optimization design scheme of the motor electromagnetic.This pa-per builds the finite element model of a permanent magnet synchronous motor(PMSM),applies reasonable material properties and constraints to perform NVH simulation analysis,and verifies the accuracy of the simulation through the prototype testing.
Key words: NVH stimulation; permanent magnet synchronous motor; electromagnetic vibration noise
