Research on Finite Element Analysis and Torque Ripple Suppression of the Switched Reluctance Motor

Abstract

Abstract To repress the torque ripple of the switched reluctance motor, this study takes a three-phase 12/8-pole switched reluctance motor as an instance and simulates the electromagnetic field of the motor using Maxwell finite element software to analyze the influence of electromagnetic characteristics and pole arc parameters on the torque ripple of the motor. In conjunction with the Workbench platform, the response surface method and multi-objective genetic algorithm are used to optimize the pole arc coefficients so the average torque of the optimized motor meets the operating requirements while the torque ripple is suppressed. The findings demonstrate that various structural parameters have diverse impacts on motor torque and that multi-objective optimization can significantly diminish the torque ripple of the motor.
