Compensation of cogging torque for flux-switching permanent magnet motor based on current harmonics injection

Abstract

The flux-switching permanent magnet (FSPM) machine exhibits the advantages of high power density and large torque capability. However, due to the high airgap flux density produced by magnets and the doubly-salient structure, the resultant cogging torque is relatively large, which is unfavorable for high performance drive system. In this paper, instead of… (More)
