A pair of stators that are arranged opposite to each other with a predetermined distance in the direction of the rotation axis, and a stator that is magnetized in the direction of the rotation axis so as to form a plurality of magnetic domains and within the above distance. A step motor comprising a rotor having a disc-shaped magnet rotatably arranged in the rotor, the rotor passing through substantially the center of the disc-shaped magnet and having a space formed inside in the axial direction. A flat rotor type step motor characterized by having a rotating shaft cylinder. 2. The step motor according to claim 1, wherein the rotating shaft cylinder is made of a magnetic material and is magnetically connected to each stator to form a magnetic circuit. 3. Each stator is composed of a coil, a cylindrical yoke case that houses the coil, and a yoke plate that is placed opposite to one surface of a disc-shaped magnet and that engages with the peripheral end of the cylindrical yoke case. 3. The step motor according to claim 2, wherein a magnetic circuit is formed by a rotating shaft tube made of a magnetic material, a cylindrical yoke case, and a yoke plate. 4. The step motor according to claim 2, wherein each stator has a bearing made of a magnetic material.
