This paper describes sensorless vector control of induction motor using speed observer in steady state. In sensorless vector control of induction motor, the proposed speed observer is consists of q-axis voltage of controller and real current. This paper investigates the speed characteristics when a step change of speed reference. This is verified by simulations and experimental results.
