A plurality of stator teethare arranged at a constant interval in a circumferential direction on the inner circumferential face side or the outer circumferential face side of a ring-shaped stator corethat is made of a plurality of steel plates. The winding wireis wound about the stator teeth. An insulatorthat electrically insulates the stator core and the winding wire is provided therebetween. A gapis formed between the winding wire and the insulator. Accordingly, a desired distance can be secured between the stator teeth and the winding wire regardless of the thickness of the insulator, and, thus, the influence of leakage magnetic fluxes that acts on the winding wire can be reduced. Accordingly, the influence of leakage magnetic fluxes formed near the stator teeth that acts on the winding wire can be reduced regardless of the thickness of the insulator.

Stator and electrical apparatus

The motor of the invention is an outer rotor type motor, and a rotor includes a cylindrical rotor frame that is opened at one end thereof in an axial direction, and a hollow cylindrical magnet attached to an inner periphery of the rotor frame. The magnet has a joining portion joined to an inside cylindrical portion of the rotor frame, and a protruding portion that further protrudes in the axial direction from one end, the outer diameter of the protruding portion is larger than the inner diameter of the rotor frame, and the joining portion is directly brought into close contact with a portion ranging from the one end to at least a portion of the inside cylindrical portion.
