Traditional synchronous motor system has complicated structure and is difficult to maintain. In view of the mentioned problem, this paper aims to propose a new structure brushless synchronous motor where AC exciter and synchronous motor using the same core. Two concentric single-phase winding grooves are cut on stator and rotor respectively, with the stator single-phase field winding laying in the stator single-phase winding groove, and the rotor AC induction winding laying in the rotor single-phase winding groove. The AC power from AC exciter is rectified by the rotating rectifier for the DC field winding. The results of the proposed structural design and FEA of the new structure brushless wound field synchronous motor show that the new structure is simple in structure, low in loss, high in efficiency and promising in its future application.
