In this article, J-M transformation control strategy is presented and is different from the two classical strategies of vector strategy and direct torque control strategy. The main feature of this method is that the motor torques are separated into positive and negative torque. The positive or negative rotation speed of the motor is controlled directly by the positive and negative torque to improve the efficiency of motor control. In this method, the direct control variable is a single current component, which generates not only the flux but also the torque.
