摘要： A motor stator of the invention is provided with a laminated stator core comprising a plurality of core pieces having teeth and linked by intermediate thin-wall portions. The thin-wall portions are bent to form the stator core into an annular shape with two ends of the stator core joined by welding, and slots are formed between adjoining pairs of the teeth. A welded portion of the stator core is not near a center line in a radial direction of any of the slots.

摘要： 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.
摘要翻译：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。

摘要： The N1(s) turns of an output winding is divided by a split ratio α into N1a(s) turns of an output winding (1a) and N1b(s) turns of an output winding (1b). The output winding (1a) is continuously wound around all slots as the undermost layer. Output winding 2, which is different in phase by 90 degrees from the output winding (1a), is continuously wound around all the slots over the output winding (1a). An output winding (1b) is continuously wound around all the slots over output winding 2. This equalizes the contribution of the output winding and output winding 2 to the flux linkage, thereby achieving high angle detection accuracy.

摘要： The N1(s) turns of a first output winding is divided by a split ratio α into N1a(s) turns of a lower-layer first output winding and N1b(s) of an upper-layer first output winding. The lower-layer first output winding is continuously wound around all slots as the undermost layer. A second output winding is continuously wound around all slots over the lower-layer first output winding. An upper-layer first output winding is continuously wound around all slots over the second output winding. The split ratio α is adjusted only in the slots where the detection accuracy decreases. This equalize the contribution of the first output windings and the second output winding to the flux linkage, thereby achieving high angle detection accuracy.
