この場合、アリ１０が巻線６に隣設するが、巻線６がボ
ビン５に施されており、しかも鍔すが形成されているた
め、巻線６に対する悪影響を遮断することができ、巻線
６の不良発生の原因を生じることはない。In this case, the dovetail 10 is placed adjacent to the winding 6, but since the winding 6 is attached to the bobbin 5 and a flange is formed, it is possible to block the negative influence on the winding 6. This will not cause any defects in the wire 6.
さらに、ボビン５に外径方向に余計に巻線６を施すよう
に形成し、放射状の磁路２に嵌合することにより、高密

径側に衝合することにより、極めて正確に歯部３が径方
向に位置決めされ、歯部３の内径と回転子との空隙が小
さくできる。Furthermore, in terms of manufacturing, the tooth portion 3 and the yoke portion 4 can be combined extremely accurately by aligning the shoulder pattern near the dovetail 10 of the tooth portion 3 with the inner diameter side of the yoke portion 4. The toothed portion 3 is positioned in the radial direction, and the gap between the inner diameter of the toothed portion 3 and the rotor can be reduced.
この様な歯部３の内径側に形成される回転子との空隙は
