Claims

[Scope of utility model registration request]

disc-shaped first and second permanent magnets that are magnetized in the axial direction and formed with multiple poles so that different magnetic poles are formed alternately in the circumferential direction; a rotating shaft in which permanent magnets are arranged in parallel in the axial direction, and a pair of magnetic pole teeth facing the magnetic poles and arranged oppositely on both sides in the same direction as the axial direction of the rotating shaft of the first permanent magnet. and a stator disposed oppositely on both sides in the same direction as the rotation axis of the second permanent magnet, facing the magnetic pole of the second permanent magnet and peripherally facing the magnetic pole teeth of the first stator. a second stator having a pair of magnetic pole teeth shifted by an electrical angle of 1/2π in the direction; a pair of coils, and magnetic pole teeth located between the first permanent magnet and the second permanent magnet of the first stator and the second stator are each formed in a magnetic disc. are radial comb teeth protruding from the outer periphery of the magnetic disc toward the center; the magnetic discs are overlapped with each other, and the magnetic body is A step motor characterized by integrally connecting discs.
