Abstract
Disclosed are a sensorless induction motor system including a controller configured to control operation of a motor by controlling a voltage applied to each phase of a stator, to set a stop waiting time expected to be required for the rotor to stop during stop control of the motor, to apply a pulse voltage to each phase of the stator a plurality of times after the stop waiting time, and to determine that the rotor is stopped when rotor position vectors having largest induced current deviations are observed as the same rotor position vector, and a control method thereof.
