Introduction was made to the development process of brushless doubly-fed machines and the actuality of research on brushlessdoubly-fed machines in domestic colleges and universities at present. This paper analyzed the principle and structure of brushless doubly-fedmachines, summarized the advantages and disadvantages of different stator and rotor structure, and expounded the application situation ofbrushless doubly-fed machines. It is pointed that brushless doubly-fed machines needed to be optimized further on the design of stator windingand rotor winding to reduce harmonics produced by rotors which could impact on motors operation and make the operational processmore energy-saving and stable.
