Claims

[Scope of utility model registration request]

An outer iron core formed in an annular shape, a plurality of field magnets fixed at equal intervals along the inner peripheral surface of the outer iron core, and a winding wire arranged inside each of the field magnets. In the outer rotor type motor, the outer iron core has the same number of V-shaped grooves as the field magnets formed at equal intervals along the circumferential direction of the inner peripheral surface thereof. In addition, a non-magnetic material is embedded in each of the grooves, and each of the field magnets is fixed to the outer iron core with a central portion thereof facing a portion where the groove is not formed. Outer rotor type motor.
