© 2017 IEEE. Flux-switching permanent magnet machines (FSPMMs) have been investigated for hybrid electric vehicles (HEVs). This paper presents an optimal FSPMM with 12 stator poles to meet the minimal performance specifications required by the drive machine in the 2010 Prius HEV. After a qualitative analysis based on size equation to briefly compare performances of FSPMMs with four rotor topology structures, a quantitative analysis method based on multilevel optimization method and finite element analysis model is presented to obtain an accurate performance comparison. It is found that FSPMMs with different topology structures have different optimal structural parameters, and the optimal one with 13 rotor poles has the best performances in terms of output power and efficiency among four different rotor structures. The proposed method can be employed as an accurate design optimization and comparison method for FSPMMs with different topology structures and highly dimensional structural optimization parameters.
