Abstract: A novel strategy for the direct control of the torque and field currents applied to the six-phase induction motor drive was proposed in this paper. This novel current control strategy benefits the developed torque of the motor as well as simplifying the control algorithm by removing the complex transformations used. The main performance of the six-phase machine including the machine modelling is determined with finite element analysis (FE). Furthermore the control strategy proposed is experimentally verified by using the six-phase induction drive system built. All the methods/approaches were proven that the field and torque current components of the six-phase machine can be controlled separately without any coordinate transformation. As such emulation separately excited DC motor control.
