Multi-Objective Design Optimization of a Hybrid Excitation Flux Switching Permanent Magnet Motor Based on Design Sensitivity Analysis

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