The compact and robust rotor structure also makes stator-PM machines potential candidates for high speed applications. Meantime, the air-gap flux regulations can be realized by hybrid excitations of PMs and field windings, which consequently expands the speed adjustment regions. Overall, the stator-PM machine features the definite advantages of robust structure, high power density and efficiency, high 0 fault-tolerant capability and being applicable of various control strategies. In this paper, a comprehensive and systematical overview on the stator-PM brushless machine systems and their key technologies is conducted, with particular emphasis on machine topologies, operation principles, design and analysi
