... designed to control a brush-less DC motor. However, by
constructing a feedback loop that can detect the outputs of an induction motor, we
can use this motor controller to control an induction ... for a three -phase induction motor drive. This induction
motor drive is proposed to be incorporated into a “hybrid car” or an “electric car”.
