Abstract
This paper develops the concept of employing the redundant winding in a flux-switching permanent magnet (FSPM) machine. A new redundant FSPM machine is proposed for fault tolerant operation of critical applications. The redundant winding configuration is analyzed and the corresponding suitable control strategy for the post-fault is proposed. The electromagnetic performance of the redundant FSPM machine drive under normal and fault conditions is predicted by using a co-simulation method coupling magnetic and electrical circuit solvers. Finally, a 12/10-pole FSPM machine with redundancy is prototyped for verification. Both simulation and experimental results are presented, verifying fault tolerant characteristic of the proposed machine drive.
