In our previous research, flux-switching permanent magnet machine (FSPMM) was investigated for the application in hybrid electric vehicles. To obtain the best performance of the whole drive system, a new multilevel design optimization method is presented for this kind of machine and a field oriented control system. The proposed multilevel optimization method is based on sequential subspace optimization method. In the implementation, three levels are employed to obtain the optimal design scheme at the system level. Meanwhile, sequential optimization method is employed to reduce the computation cost of finite element analysis on the motor level. Finally, from the design analysis, it can be found that the proposed method can provide design scheme with better performance, while the needed computation cost is reduced greatly for this FSPMM drive system.
