英文摘要：

The novel torque control strategy of a six - phase induction machine is studied. Based on the control method proposed, the system performance with the direct control technique is verified by a developed Matlab simulation model and measurements on a small （2 kW） two -pole, six -phase induction motor drive under digital hysteresis current control. It is shown that the calculated results from theoretical derived equations are in good agreement with measured results. The simulated and measured results show that there is a linear relationship between the torque and torque current when MMF balance is maintained in the motor bythe drive controller independent of the load condition. The direct control of the torque has the good dynamic performance for the proposed control strategy.
