The bobbin 5 on which only the main winding is wound may have two terminals 7, and when the auxiliary winding is wound on the bobbin 5a, the terminal 7 may be mounted on the bobbin 5a.
The required number increases, such as 4 a.
しかし、ボビン５．５ａの形状は変らず、同じ成形型で
成形製作したもので良く、製作の都合が良くなる。However, the shape of the bobbin 5.5a does not change, and the bobbin 5.5a can be molded and manufactured using the same mold, which improves the convenience of manufacturing.
一方、歯部３を継鉄部４に嵌合するには、相当の押圧力
を要するが、アリ１０をアリミゾ１１に嵌合するように
位置付け、プレスなどによってアリ１０を押圧すること

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は、歯部３の磁路２に嵌合される際、
圧入によらなくとも、遊嵌状態であっても良く、樹脂で
モールド成形することによって固定されるため揺動する
こともなく、振動やトルクムラの原因になることもない
。Furthermore, when the bobbin 5 is fitted into the magnetic path 2 of the tooth portion 3,
It does not need to be press-fitted, but may be loosely fitted, and since it is fixed by molding with resin, it does not swing or cause vibration or torque unevenness.
また、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、およびこれら
を樹脂で一体にモールドすることにより、高密度の巻線
構造を得ることができ、小形で高出力の電動機を構成す
ることができる。In addition, by forming an extra winding 6 on the bobbin 5 in the outer diameter direction, fitting it into the radial magnetic path 2, and integrally molding these with resin, a high-density winding structure is achieved. It is possible to obtain a small, high-output electric motor.
さらに、製造面において、歯部３と継鉄部４とを化合す

径側に衝合づることにより、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 part 3 and the yoke part 4 can be joined together extremely accurately by aligning the shoulder pattern near the dovetail 10 of the tooth part 3 with the inner diameter side of the yoke part 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.

なる。The gap formed on the inner diameter side of the teeth 3 between the rotor and the rotor may be adjusted by mechanical cutting, but even if it is large and the loss increases, the gap between the rotor and the rotor formed on the inner diameter side of the tooth portion 3 may be adjusted, but even if it is large and the loss increases, the gap between the rotor and the rotor is In the winding method in which the wire is wound around the toothed portion 3 by the spring 166
In addition, since the flange of the bobbin 5 forms a curved surface along the yoke 4, the wire area ratio, that is, the winding 6 can be wound in large quantities between the teeth 3. There is an aspect of efficiency that improves, and as a result, there is less deterioration of efficiency.
