Torque ripple mitigation of double stator switched reluctance motor (DSSRM) using a novel rotor shape optimization

In This paper, an effective torque mitigation technique for double stator switched reluctance motor (DSSRM) using rotor shape optimization technique is presented. This method results in the lower torque pulsation without significant reduction in the average torque. The method is based on shape optimization of the rotor for redistribution of the flux so that the inductance profile has smoother variation as the rotor poles move into alignment with excited stator poles. The results show that this simple shape optimization has profound effect on the torque ripple reduction.
