タとを備えたステツプモータ。 A pair of hubs are brought into contact with both sides of the edge of the center hole of a ring disk-shaped permanent magnet with a large number of magnetic poles magnetized in the circumferential direction so as to form a gap where the inner circumferential side of the edge is not in contact. A step motor comprising: a rotor that is glued together and has a rotating shaft at the center of the hub; a stator core that has magnetic pole teeth on an opposing surface facing the magnetic poles of the permanent magnet; and a stator that has a coil that excites the stator core.
