Abstract：In this paper, a kind of new type of magnetic resistance brushless doubly-fed motor rotor structure is introduced to the design of rotor structure which is designed based on the magnetic resistance structure combined with wound rotor type structure. This rotor structure has kept the flexibility of connection mode of the wound rotor winding, and played the oriented functions of reluctance rotor flux, improving the effect of magnetic field modulation, It can realize commendably to maximize coupling ability of two sets of rotor and stator winding. It has been analyzed detailly of the design principle and method of the structure of a new type of reluctance rotor brushless doubly-fed motor in this paper, as a case study of a 30kW·A prototype showed that the power distribution curve, the air gap flux density curve and motor efficiency of the new type of magnetic resistance of brushless doubly-fed motor, and contrasted with the structure of the magnetic barrier and magnetic resistance,adding the cage of reluctance rotor brushless doubly-fed motor output power in the same conditions. Finally,the dynamic performance of the prototype of the brushless doubly-fed generation system has been tested. The experimental results shown that the new type of magnetic resistance brushless doubly-fed motor which is designed by this manner has achieved excellent performances.
