Effects of inter-turn fault in phase winding on the performance of multi-phase doubly salient motors

Abstract This paper presents the results of a 2-D Finite element analysis carried out on switched reluctance motor and doubly salient permanent magnet motor (DSPM) to study the effects of inter-turn fault in phase winding on the average torque, ripple torque, and the phase inductance. It is shown that the DSPM has an inherent advantage of partial withstand to inter-turn faults.
