Abstract
A sensorless induction motor system includes a control unit which applies a plurality of sampling pulse voltages to phases of the stator, estimates the position of a rotor through a first rotor position vector having the greatest deviation in an induced current, compares an induced current deviation of a second rotor position vector having a second greatest deviation of deviation of the induced current with that of a first rotor position vector, and determines whether or not permanent magnets are demagnetized; and a method of controlling the sensorless induction motor system.
