Abstract: In order to solve the electromagnetic vibration problem of in-wheel motors for electric vehicles, a numerical analysis method is presented for analysing the modal of in-wheel motor. The finite element models of inner stator core, inner stator core with winding and outer rotor are established respectively. The analysis results show that the higher the order of modal vibration shape, the higher the natural frequency. The critical speed of the outer rotor is analysed and studied, which shows that the outer rotor will not cause greater vibration to the in-wheel motor when it works. The harmonic response of in-wheel motor is analysed and the displacement-frequency curves of inner stator and outer rotor are obtained respectively. The analysis results show that the in-wheel motor is not in the frequency range of electromagnetic force wave. When the frequency is higher, the deformation displacement amplitude will reach the maximum.
