Switched reluctance motors (SRMs) are becoming increasingly popular in the automotive sector owing to their robust design. Moreover, SRMs are preferred particularly for EV applications owing to their fault tolerance, magnet-free structure, and high power/torque density. The main concerns of SRM compared to other machines include torque ripple and vibration. The primary cause of vibration is the radial force created by the SRM. A geometry-based modification of the SRM to reduce the radial force without significantly changing the average torque produced is proposed. The primary goal is to design a 4-phase, 8/6 SRM with a lower radial force. Two possible geometrical alterations are proposed: one with square windows and the other with circular holes on the rotor core.The windows are sized and positioned to avoid flux saturation. General criteria are developed for the optimal window size and placement. Finite element analysis (FEA) modelling of the SRM is used to validate its performance. The FEA results are compared with the performance parameters obtained using the analytical method. Utilizes the multiphysics design tool ANSYS to obtain the natural frequencies and associated deformations through modal analysis. Compared to the conventional geometry, the radial force is significantly reduced by providing windows.

In view of the problem of large torque ripple and poor output performance of permanent magnet synchronous motor, a new topology of asymmetric magnetic pole permanent magnet synchronous motor is proposed, and the torque ripple of this motor structure and the suppression method are analyzed. First, the equivalent magnetic circuit method and Lorentz force law are used to derive the analytical formula of torque ripple of the motor. Then, based on the analytical formula, the parameters of permanent magnet of the asymmetric magnetic pole permanent magnet synchronous motor are optimized and verified by finite element software simulation; on this basis, the method of rotor eccentricity is used to further weaken the torque ripple of the motor, and the optimal eccentricity distance is analyzed. The research shows that when the parameters of the magnetic pole of the asymmetric magnetic pole permanent magnet synchronous motor is appropriate, the harmonic content of the air gap magnetic density of the optimized motor is greatly reduced, and the motor has good output characteristics, and the torque ripple is reduced to 5.4%. Finally, the prototype is trial‐manufactured and tested. The results show that after optimization, the cogging torque of the motor is reduced, the torque output performance is improved, and the overall motor performance is improved. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
