In this paper the sensorless induction motor drive performance with current-based MRAS speed and rotor flux estimator are tested in the wide speed range operation. This system has been equipped with additional estimator of the magnetizing reactance reconstruction. Methodology is based on the well known mathematical interpolation of the inverse magnetizing curve. Dynamical performances of the vector control system with such this current-type MRAS estimator with magnetizing reactance on-line
