摘　　要：双凸极电机结构简单、可靠性高、成本低且能量密度大,应用前景广阔。此处以三相12/8极电励磁双凸极电机(DSEM)为研究对象,分析和比较了三相三状态(TPTS)、TPTS提前角(TPTS AAC)、三相六状态(TPSS)与三相九状态(TPNS)控制策略的异同。借助Maxwell有限元仿真软件,从提前角的大小及桥臂开关管的导通时长的角度出发,研究换相策略对电机损耗的影响。并设计实验对仿真结果进行了验证。The doubly salient motor has a simple structure,high reliability,low cost and high energy density and has broad application prospects.Three-phase 12/8 pole doubly salient electro-magnetic motor(DSEM)is studied.The similarities and differences of three-phase three-state(TPTS)control strategy,TPTS advance angle control(TPTS AAC)strategy,three-phase six-state(TPSS)control strategy and three-phase nine-state(TPNS)control strategy are analyzed and compared.The influence of the commutation strategy on the motor loss is studied from the perspective of the advance angles and the conduction time of the bridge arm by Maxwell finite element simulation software.The design experiment is carried out to verify the simulation results.
