Claims

[Scope of utility model registration request]

A stator having an annular yoke in which a plurality of magnetic pole parts each having a plurality of pole teeth on the inner peripheral surface are planted radially at an appropriate pitch, and both ends of the annular yoke are connected to both sides of the annular yoke. an excitation magnetic pole wound with a winding wire, and pole teeth on the outer periphery of the excitation magnetic pole, which are arranged opposite to the inner peripheral surface of the stator with a gap in between.
1. A stepping motor comprising a rotor shaft consisting of two disc-shaped rotor magnetic poles, a permanent magnet held between the rotor magnetic poles, and a rotor shaft.
