The traditional induction motor equivalent circuit defects due to the neglect of iron loss. This paper analyzes the equivalent circuit of the induction motor considering iron loss and derives the basic equations of the motor in the two-phase stationary reference frame and the two-phase rotating reference frame. On this basis, an extended Kalman filter observer based on the model of induction motor considering iron loss is designed to observe the speed and rotor flux of induction motor. Besides, a speed sensorless vector control system is realized, and the performance of Kalman filter observer and speed sensorless technology is verified by theoretical and experimental results.
