Abstract :
Taking core loss into account has import effect to improving the torque performance of direct field oriented control for induction motors. In this paper, the transient mathematical model of induction motor with core loss is proposed. The method is presented to minimize the loss in a variable speed and torque at the rotating coordinate, and simulated results show that the efficiency is improved evidently at light load.
