Abstract
The hybrid excitation flux switching permanent magnet (HEFSPM) motor with magneticbridge is a topology of hybrid excitation flux-switching PM machines. Despite its excellent performancesuch as high torque/ power density, high flux enhancing/ weakening capability and so on, it has receivedless attention due to its complicated structure. Therefore, its optimal design and performance all need tobe further investigated. This paper presents an optimal design of a HEFSPM motor with magnetic bridge.At first, the machine structure and basic working principle are discussed briefly. Then, a design sensitivityanalysis for geometric optimization is carried out to improve the motor performance. This optimizedmotor is compared with initial design. Finally, a prototype of the optimized proposed motor is built andtested to validate the simulation results.
