英文摘要： This project comes up with a novel fault-tolerant machine with permanent magnets in the stators which is termed as axial field flux-switching fault tolerant(AFFSFT) machine for electric vehicle applications. Incorporated the advanced features of dual stators,one rotor and hybrid excitation, the machine combines the advantages of simple structure and high power/torque density.The two sets of excitation sources including the permanent magnets and the electrically excited winding are provided, and this increases the starting torque and the adjustable speed range of AFFSFT machine. Meanwhile, the fault-tolerant performance of the machine is greatly improved due to the specific structure design. This project aims at studying and analyzing the new topology, design principles, electromagnetic characteristics, accurate calculation of the parameters and the control method of the electric machines. We will extend the research to various aspects including the electromagnetic and optimal design of the machine,the general method of the steady and transient performance analysis of the machine and its control system, the coordination control of the armature and the DC excitation current and the on-line efficiency optimization method, and the fault remedial strategy. The hardware control platform based on the dSPACE will be es
