摘要：

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 experimental results verify the validity of the proposed topology and control method. ©2015 Chin.Soc.for Elec.Eng.
