ABSTRACT
In this paper, three advanced partitioned-stator flux-switching (PS-FS) motors with different topologies, namely the PS-FS permanent-magnet (PS-FSPM), the magnetless PS-FS direct-current (DC)-field (PS-FSDC), and the hybrid PS-FS hybrid-excitation (PS-FSHE) motors are carefully compared. Upon the employment of high-energy-density PM materials, the PS-FSPM motor can provide superior torque and power performances. Meanwhile, the magnetless PS-FSDC motor can instead offer better cost-effectiveness and higher flux-regulating capability. By incorporating two excitation sources, the hybrid PS-FSHE motor can therefore enjoy the advantages from both extreme sides. All the proposed PS motors are highly desirable for the hybrid electric vehicle (HEV) applications, while all of their key performances are analysed and compared with the profound Toyota Prius HEV motor.
