Abstract
This paper presents the comparative studies of two permanent magnet (PM) motors, which are modular-stator outer-rotor flux-switching permanent-magnet (MSOR-FSPM) motor and conventional outer-rotor flux-switching permanent-magnet (COR-FSPM) motor. The differences in structure and design principles between the two types are compared. Then, a 2D finite element method (FEM) is used to analyze the basic electromagnetic performances. The magnetic field distribution, no-load back-EMF, cogging torque, and electromagnetic torque are presented and compared. Furthermore, a comprehensive comparison of the motor performances which are important for electric vehicles is investigated. The theoretical analysis and FEM results predict that the MSOR-FSPM motor has superior capability compared to that of the COR-FSPM motor, including fault tolerance capability, and field weakening capability.
