Abstract

The hybrid excitation flux switching permanent magnet (HEFSPM) motor with magnetic
bridge is a topology of hybrid excitation flux-switching PM machines. Despite its excellent performance
such as high torque/ power density, high flux enhancing/ weakening capability and so on, it has received
less attention due to its complicated structure. Therefore, its optimal design and performance all need to
be 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 sensitivity
analysis for geometric optimization is carried out to improve the motor performance. This optimized
motor is compared with initial design. Finally, a prototype of the optimized proposed motor is built and
tested to validate the simulation results.
