A variable gap motor has a rotor that rotates along the circumferential direction of the stator in a direction opposite to the rotation, and a position detector that detects the revolution position of the rotor of the variable gap motor and outputs a revolution position signal. In the variable gap motor device, the surface of the rotor is alternately magnetized in the circumferential direction, and the required coils of the stator are arranged to generate electromagnetic attractive force and electromagnetic repulsive force in accordance with the revolution position of the magnetized rotor. A variable air gap motor device characterized by magnetization.
