摘      要：In the design of the motor used for electric vehicles(EVS),vibration and noise problems are often ignored,which reduce the reliability and service life of the *** this paper,an interior permanent magnet synchronous motor(IPMSM)with high power density is taken as an example,and its electromagnetic vibration and noise problem is investigated and ***,the factors that generate the electromagnetic force harmonic of IPMSM are analyzed by theoretical ***,the mode and electromagnetic harmonic distribution of the motor are calculated and analyzed by establishing the electromagnetic-structure-sound coupling simulation ***,by combining finite element method(FEM)with modern optimization algorithm,an electromagnetic vibration and noise performance optimization method is proposed in the electromagnetic design stage of the ***,an IPMSM is optimized by this method for electromagnetic vibration and noise *** results of comparison between before and after optimization prove the feasibility of the method.
