Abstract
A concentricity control apparatus induction for controlling a concentricity between a stator body and a rotor body in an induction motor. The concentricity control apparatus for a concentricity controlling induction motor has a sensor for detecting an eccentricity of a rotor body, an operating unit for operating an electrical current in order to correct an eccentricity according to the detection of the sensor, and a driving circuit for controlling the electrical current of the rotor body. A core control unit so constructed as to apply to a core direction of the rotor body an electromagnetic force perpendicular to a central rotating shaft of the rotor body.
