摘要：
The vibration and noise level of the permanent magnet synchronous motor (PMSM) directly affects the NVH performance of the electric vehicle. The electromagnetic noise characteristics of a permanent magnet synchronous motor driven by an electric vehicle were studied and optimized based on the theoretical analysis and Ansys multi-physics field finite element analysis platform. The electromagnetic noise of the motor was mainly derived from the electromagnetic excitation force of the stator tooth, different rotor structures can have different effects on the magnetic field, in this paper, by optimizing the structure of the rotor magnetic bridge, the electromagnetic excitation force of the stator teeth of the motor was changed to reduce the vibration and noise of the motor. The finite element model of the electromagnetic field before and after the optimization was established, and the electromagnetic excitation force acting on the stator of the motor was simulated, and the 3D finite element model of the motor structure before and after the optimization was established, the radial modal frequency of the motor structure was calculated. The vibration response spectrum of the stator structure of the motor was obtained by the finite element simulation of the vibration response of the stator structure of the motor. Finally, the electromagnetic noise characteristics of the motor were obtained through ANSYS Acoustics finite element simulation analysis. The results show that the optimized motor can reduce the vibration and noise of the motor effectively. The validity of the simulation results is verified by experiments. © 2019 Chin. Soc. for Elec.
