Claims

[Scope of utility model registration request]

In a stepping motor that has a large number of teeth formed on the inner periphery of the main pole provided by one stator and on the outer periphery of the rotor, the opposing main poles are wound with the same polarity and the opposite polarity is arranged at 90° intervals. A stepping motor characterized by being a 3-phase 4-pole excitation type.
