Comparative Analysis of a Novel Flux-Switching Arc Permanent Magnet Machine With Flux-Reversal Effect

This paper proposes a novel flux-switching arc permanent magnet (PM) machine (FSAPMM) with flux-reversal effect to improve the electromagnetic performances of conventional arc permanent magnet (APM) machine. The ending effect of APM is reduced by adopting a cross and concentrated winding connection. The electromagnetic performance of the proposed FSAPMM was analyzed and compared with the conventional FSAPMM and flux-reversal APM machine (FRAPM) by using finite element analysis (FEA) method after optimization. The results show the proposed FSAPMM has the highest back-electromotive force (EMF) amplitude, average torque and the lowest cogging torque.
