Development of partitioned stator flux-switching machines for electric vehicles

In this paper, three advanced partitioned stator flux-switching permanent-magnet (PS-FSPM) machines with different number of phases, namely the 3-phase, the 4-phase, and the 5-phase are comprehensively compared. Owing to the higher-phase topology, better fault-tolerability and higher power density can be achieved. On the other hand, higher-phase machine suffers from the problem of relatively lower cost-effectiveness. Hence, trade-off between different criteria should be considered to fulfill various situations. In particular, all the PS-FSPM machines are highly favorable for the electric vehicle applications, while all of their key performances are analyzed with the support of the finite element method
