ングモータ。It is equipped with a stator and a rotor rotatably arranged in a hollow part of the stator.The rotor is made of a permanent magnet and has N poles and S poles alternately provided in the circumferential direction. In a permanent magnet type stepping motor, the rotor is rotated by sequentially exciting the stator magnetic pole teeth. A comb-shaped S-pole member having S-pole magnetic pole teeth and a comb-teeth-shaped N-pole member having a plurality of N-pole teeth at predetermined intervals in the circumferential direction are formed separately, and the magnetic pole teeth and A permanent magnet type characterized by being formed into a cylindrical shape by interlocking and connecting the S and N pole members so that the magnetic pole teeth of another magnetic pole member fit into the grooves between the magnetic pole teeth. stepping motor.
