    • A plurality of stator teeth 2 are 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 core 1 that is made of a plurality of steel plates. The winding wire 5 is wound about the stator teeth. An insulator 4 that electrically insulates the stator core and the winding wire is provided therebetween. A gap 6 is 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.
    • 多个定子齿2在由多个钢板制成的环状定子铁心1的内周面侧或外周面侧沿周向以一定的间隔配置。 绕组线5缠绕在定子齿上。 将定子铁芯和绕组线电绝缘的绝缘体4设置在其间。 在绕组线和绝缘体之间形成间隙6。 因此,不管绝缘体的厚度如何,可以在定子齿和绕组线之间确保期望的距离,因此可以减小作用在绕组线上的泄漏磁通的影响。 因此,无论绝缘体的厚度如何,可以减小作用在绕组线上的定子齿附近形成的漏磁通的影响。
