Abstract

This paper proposes a novel consequent pole hybrid magnet vernier memory machine (CPHM-VMM) featuring alternatively arranged NdFeB and low-coercive force (LCF) magnet poles on the rotating and stationary sides, respectively. Due to the existence of bidirectionally magnetized LCF magnets, CPHM-VMM can simultaneously perform high torque production in low-speed region, and excellent high-speed flux-weakening performance with negligible excitation loss. The topology and operating principle, as well as the design considerations of CPHM-VMM are described and its electromagnetic performance is investigated.
