摘　　要：由于多相电机控制模式相对复杂,该文提出一种新颖的控制方式:即在六相感应电机定子侧通入梯形波相电流,使得其中三相为励磁绕组,另外三相为转矩绕组,从而实现励磁磁链和转矩磁链解耦模拟直流电机控制模式而省去复杂的派克变换。本文主要对磁势解耦时转子磁链和转子感应电压、电流进行了理论和有限元分析和计算,并实验测量了梯形波相电流驱动下六相感应电机转子感应电压、电流,结果表明有限元分析和实验结果是一致的。As the control mode of the multiphase machine was more complex , a novel control method was proposed in this paper. The trapezoidal wave phase current were connected into the stator of the six-phase in- duction machine . By using the trapezoidal phase current waveform, the stator winding was separated into the field winding and the torque winding, which making the field and torque control in directed and separa- ted mode can be realized without the complex Park transformation. Analytical calculation of the rotor flux linkage and induced voltage and current as MMF decoupling. Two methods were used to verify the rotor in- duced voltage of the motor namely finite element calculation and practical measurements. The result of the rotor induced voltage and current obtained from these methods show good agreement.
