Abstract

Due to the inherent flux-focusing effect as well as the elimination of the flux-barrier effect, consequent-pole flux-switching permanent magnet (CP-FSPM) machines have attracted growing attention in recent years. Furthermore, the simple and robust salient-pole rotor structure of CP-FSPM is suitable for in-wheel traction applications when the outer rotor (OR) layout is adopted. In order to investigate the applicability of OR CP-FSPM machines in traction applications, three typical machines with II-shaped, V-shaped, and U-shaped permanent magnet (PM) arrangements and a proposed machine with an improved inclined U-shaped PM arrangement are comprehensively analyzed and compared in this study. A simplified semi-analytical magnetomotive force (MMF)-permeance model is established to analyze the flux modulation effect of different PM excitations. In addition, the global optimization of these machines is conducted, and the on-load performance of the optimized machines is investigated and compared. As a result, the proposed inclined U-shaped PM machine exhibits the highest torque density among various CP-FSPM machines with the same PM volume, while the torque ripple is kept at a low value.
