[Abstract]:According to the Maxwell stress equation, the analytical expression of radial electromagnetic force of permanent magnet synchronous motor is derived, and the internal order of the motor and the source of radial electromagnetic force of each frequency are analyzed and summarized. Taking a 45-slot 10-pole permanent magnet synchronous propulsion motor as an example, the electromagnetic finite element model and the structural finite element model of the motor are established, and the modal analysis is carried out. The radial electromagnetic force obtained from the electromagnetic finite element model is coupled to the structural finite element model, and the harmonic response of the electromagnetic vibration of the motor is analyzed. Finally, by comparing the measured acceleration spectrum of the prototype with the finite element simulation results, the correctness of the radial electromagnetic force analytical formula and the finite element simulation results of the electromagnetic vibration are verified.
