Disclosed is a rotor including a sleeve part having a shape corresponding to a cylinder extending in a reference direction, and having an inner hole extending in the reference direction, in an interior thereof, a division part disposed in the inner hole, and dividing the inner hole into a first space and a second space, together with the sleeve part, a first magnet part disposed in the first space, and a second magnet part disposed in the second space, and disposed to have an opposite polarity to that of the first magnet part when viewed along the reference direction.

Rotor and sensorless control method for rotor

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.
