Abstract

A flux-switching permanent magnet (FSPM) machine with an outer-rotor configuration is proposed for traction applications. The effects of the pole and slot numbers on back-EMF and cogging torque are studied, and sizing equations are derived to determine the machine dimensions. Finite element analysis (FEA) models are developed to optimize the machine performance including flux-weakening capability, and core losses are also estimated. Performance predictions by the FEA models are validated by the experimental tests on the prototype built from the optimized design. The suitability of the proposed machine for in-wheel traction is demonstrated.
