摘要：
Torque ripple is the main source to cause motor vibration and noise. Here, in order to reduce torque ripple of a switched reluctance motor, a new type rotor tooth profile, i.e., a semi-oval auxiliary core being added on both sides of a traditional parallel rotor tooth profile, was studied. The finite element method was used to model a 12/8-pole switched reluctance motor, and the optimal modified model was obtained through parameterized simulation. Meanwhile, to further reduce torque ripple, the switching angle of the power converter was optimized, and the torque transition caused by phase change was relieved. The combination scheme for the optimal switch-on and switch-off angles was obtained through simulation calculation. The results showed that the proposed method can not only significantly reduce torque ripple of a switched reluctance motor, but also relieve the local saturation caused by double salient-pole; the proposed method can be used as a reference for other double salient-pole motors. © 2019, Editorial Office of Journal of Vibration and Shock.
