Abstract
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.
