英文摘要： In recent years, as one of the important strategic resouces, the increasing price and shortage of the rare-earth material have become one of negative factors to the rapid development of new energy vehicles. In this project, by incorporating the theory of flux intensifying and flux controllable motor into the non-rare earth permanent magnet motor, a new flux-intensifying non-rare-earth permanent magnet motor and drive system are proposed for electric vehicles (EVs), where the advantages of high power density, high efficiency and wide speed range can be obtained. Basic operation principle, mathematical modeling and simulation as well as multi-objective optimization design method will be investigated in details. The multi-mode driving strategies will be investigated under different operation conditions. Moreover, multi-objective optimization theoretical model and the optimal control strategies will be studied to obtain the high efficiency of the whole drive system. The project will explore the alternative motor type for EVs and alleviate the crisis of rare-earth material to the development of the EVs, which can also lay a theoretical foundation and provide experimental results for the applications in EVs.
