Abstract: Fault-tolerant flux-switching permanent-magnet machine has advantages such as high fault-tolerance, simple rotor structure and high power density, and is widely used in the field of high reliability. The general design process of the machine was proposed according to the project design requirements, the parameter design formula was derived in detail, and the parameters were optimized through finite element analysis. A prototype was manufactured under the optimal parameters and an experimental platform was built to verify the correctness of the electromagnetic design.

Key words: fault-tolerant flux-switching permanent-magnet ( FT-FSPM) machine, electromagnetic design, parameter optimization
