摘　　要：整距绕组双凸极永磁电机(FMDSPM)具有高空间利用率,结构紧凑,高扭矩密度,低扭矩波动以及坚固的特征,其相绕组电流开关控制策略具有独特的特征。以6/4极FMDSPM电机为例,给出理想磁链分布和电流开关状态,得出驱动开关电路开关通断模态的四状态控制法。通过非线性模型分析和测试,其反电动势得到验证,通过动态模型分析,两相FMDSPM相绕组电流开关通断控制策略的有效性得到验证。Full-pitch winding doubly salient permanent magnet machine(FMDSPM)possesses some attractive features such as high space utilization,high torque density and low ripple of torque.There exists unique feature in switch-mode control for the driving circuit of FMDSPM.A FMDSPM machine with 6/4 pole was taken as example,the ideal flux distribution and current switch state were given,and the four state control method of driven circuit was obtained.The back-EMF was verified through analysis and test of nonlinear model.The dynamical analysis was carried out in order to validate the introduced four-state control strategy for FMDSPM.
