摘　　要：提出一种具有奇数转子极的新型五相容错式磁通切换永磁(fault-tolerant flux-switching permanent-magnet,FT-FSPM)电机。该电机结构通过引入容错齿设计,增强了各相之间的独立性,提高了电机容错性能。运用有限元方法,对所设计的10/19极FT-FSPM电机的磁场、气隙磁密、反电势及齿槽转矩等电磁性能进行计算,分析奇数转子极结构对反电势和齿槽转矩的影响。在此基础上,研究电机故障时的容错控制策略。运用电路、磁路瞬态联合仿真的方法,对电机的转矩进行计算,并设计加工了FT-FSPM实验样机,仿真和实验结果验证了理论分析的正确性。A new five-phase fault-tolerant flux-switching permanent-magnet （FT-FSPM） motor was proposed, which has odd rotor pole number. In order to improve fault tolerance, the key of the proposed motor topology is to incorporate the design method of fault-tolerant teeth to provide the desired decoupling among phases. By using the finite-element method, the electromagnetic performances of the proposed 10/19-pole FT-FSPM motor were analyzed, including the magnetic field distribution, flux density, back-EMF, and cogging torque. Particularly, the influences of odd rotor pole topology on symmetric back-EMF and low cogging torque were analyzed. Also, the control strategies of the proposed motor under normal and remedial conditions were investigated. A field-circuit co-simulation model was developed to predict torque performance of FT-FSPM motor drive under various conditions. Finally, a FT-FSPM motor was designed and prototyped. The simulated and experime0tal results verify the validity of the proposed topology and control method.
