Claims

[Scope of utility model registration request]

a cup-shaped first stator yoke having a plurality of comb-like pole teeth parallel to the rotor axis at equal intervals on an inner circumferential surface;
a second stator yoke having comb-like pole teeth located between the comb-like pole teeth of the first stator yoke; a stator winding housed in a space surrounded by a second stator yoke; and a stator winding fixed to the rotor shaft;
a permanent magnet rotor that faces the comb-like pole teeth of the first stator yoke and the second stator yoke with a slight gap, the first stator yoke and the second stator yoke; A permanent magnet stepping motor in which a stator winding is integrally molded with a synthetic resin, and the first stator yoke, second stator yoke, and stator winding are insulated and fixed by the synthetic resin part.
