Performance analysis of the six-phase induction machine based on trapezoidal phase current waveform
With the characteristic which the control of the multiphase machine is more complex compared with three-phase ac machine,a novel control method is proposed in this paper,namely six-phase motor trapezoidal wave phase current control.By using the trapezoidal phase current waveform,the stator winding is separated into the field winding and the torque winding.The function which is about the field and torque control in directed and separated mode can be realized without the complex Park transformation.The paper carries on the theoretical analysis,the computation of the air gap magnetomotive force (MMF),the electromagnetism torque and MMF decoupling parameter k.And these results are 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.
