Aiming at the vibration and noise of motor stator system, the ANSYS finite element simulation software was used to simulate the threedimensional model of the motor stator system. The natural frequency and vibration shape of the stator system were obtained. And the simulation results were verified by experiments. At the same time, the electromagnetic simulation of the motor was carried out, and the air gap flux density and the harmonic frequency of electromagnetic force harmonic were obtained. The frequency of electric magnetic harmonic frequency was compared with the natural frequency of the motor to determine that the electromagnetic force harmonic does not cause the resonance of the motor stator system. The rationality of the motor structure was verified. A certain reference value for the design optimization of the same kind of products was provided.
