摘　　要：针对传统多相电机控制模式复杂性的特点,提出一种六相感应电机新颖的控制方式,即梯形波相电流控制。把定子绕组分为励磁绕组和转矩绕组,从而实现励磁磁场和转矩磁场的直接控制而不需要复杂的派克变换。对六相电机气隙磁动势、电磁转矩和磁势解耦参数k进行了理论分析和计算,并通过实验进行验证。理论分析和实验结果表明,控制策略是可行的,且还具有其它一些优势。With the characteristic which the control of the multiphase machine is more complex compared with three-phase AC machine, proposed a novel control method in this paper, namely six-phase motor trapezoidal wave phase current control. By using the trapezoidal phase current waveform, the stator winding was separated into the field winding and the torque winding. The function which was about the field and torque control in directed and separated mode can be realized without the complex Park transformation. The paper carried on the theoretical analysis, the computation of the air gap magnetomotive force （MMF）, the electromagnetism torque and MMF decoupling parameter k. And these results were validated by the experiment. It is shown from the theoretical analysis computation and experiment result that it is possible for the control strategy proposed in this paper and it is also of some advantages not only in the control method but also for motor control performance.
