Switched Reluctance Motor has the main limitation of high torque ripple because of its doubly salient structure. This paper presents the Finite Element (FE) analysis of 5 hp, 655 V, 8/6 Switched Reluctance Motor with rotor pole shaping to reduce torque ripple. It is observed that rotor pole tip radius variation significantly affects torque ripple. Tapered rotor pole having high tip radius results into reduced torque ripple. Rotor pole tip radius is changed from 0 to 5 mm in step of 1 mm and FE analysis is carried out to obtain average torque and torque ripple. It is examined that torque ripple is reduced from 69.1 % to 39.3 % with this technique.

“…In [5], the authors made a comparison between tapering and straight stator poles. And in [6], the impact of projecting poles is also discussed. However, the impact of pole tapering of SRM with external circuit, which is important for evaluating the real operating characteristics, is not discussed.…”

This paper presents an 8/6 switched reluctance motor with tapering poles, which is capable of carrying larger current and producing larger torque while the flux density remains unchanged. And this feature makes it possible of using high temperature superconducting windings to improve the torque potential of electrical machines. Finite element analysis with commercial software is utilized to support this result.

“…From a mechanical point of view, tooth tips help to hold better the windings in the slots [17]. Moreover, the presence of tooth tips also has electromagnetic advantages like reducing cogging torque, reducing the no‐load back‐EMF harmonics as well as the on‐load torque ripples and increasing the output average torque [16, 18, 19]. It has been also found out in [16] that smaller slot openings reduce the slot harmonics and therefore the eddy currents in the magnets.…”
