Abstract:Firstly, the performance differences between permanent magnet synchronous motors and wound field synchronous motors (WFSMs) are analyzed. Meanwhile, the characteristic advantages and existing technical problems of WFSMs are pointed out. Secondly, the evolution process and technical route of brushless excitation of WFSMs is summarized. The research progress and application level of exciter excitation, harmonic excitation, and inductive as well as capacitive wireless power transmission technology in field winding non-contact power supply is clarified. Then, the existing reluctance torque utilization technology, rotor structure improvement technology and torque axis shift technology are summarized. The beneficial effects of the above technologies on the torque improvement of WFSMs are pointed out. Finally, the issues in this field are stated, and the future research focus and technological development direction are predicted.
Key wordsWound field synchronous motor    brushless excitation    harmonic excitation    wireless power transmission    torque density
