固定子の巻線やモールドに適した鉄心に関するも
のである。[Detailed Description of the Invention] Industrial Application Field The present invention provides an iron core suitable for winding and molding of a motor stator, which is made by dividing an iron core into a plurality of parts and applying a toroidal winding to the yoke portion of each slot. It is related to.
従来例の構成とその問題点
電動機固定子の巻線を固定子鉄心のスロツト毎
の継鉄部に巻装すると、コイルエンド高さを大巾
に短縮できる事は衆知の事実であるが、環状鉄心
の継鉄部にいわゆるトロイダル巻線を施すにはト
ロイダル巻線機が必要である。Conventional structure and its problems It is a well-known fact that the height of the coil end can be greatly shortened by winding the motor stator winding around the yoke of each slot in the stator core. A toroidal winding machine is required to apply so-called toroidal winding to the yoke part of the iron core.

機等の回転電機の巻線には適していない。 This wire winding machine sets the wire storage ring so as to intersect with the annular wire to be wound, winds the required electric wire in one turn around the wire storage ring, then reverses the winding ring and stores the wire. The wire is wound on the body to be wound while spitting out the wire, but the workability is extremely poor and the winding speed is slow, so winding of rotating electrical machines such as electric motors requires multiple windings. is not suitable for
そこで、トロイダル巻線機に代わる方法とし
て、特開昭55−139062号等により被巻線体である
鉄心を分割して、各分割鉄心のスロツト毎に通常
行なうフライヤー巻線を施す事が提案されてい
る。 Therefore, as an alternative to the toroidal winding machine, it has been proposed in Japanese Patent Application Laid-Open No. 55-139062, etc. to divide the core, which is the body to be wound, and apply flyer winding to each slot of each divided core. ing.
この方法によれば、分割鉄心を接合する点を除
けば、従来困難であつたトロイダル巻線を簡単に
かつ高速で行なう事ができ有用である。 This method is useful because, except for joining the split cores, toroidal winding, which has been difficult in the past, can be easily and quickly performed.
分割鉄心にトロイダル巻線をする場合、通常は
第１図の如き方法が考えられる。すなわち、分割

８に接触して断線する事を防止するために巻線ガ
イド７を電線６の周回軌跡の外側に設ける。 When winding toroidal wires on a split core, the method shown in FIG. 1 is usually considered. That is, the tooth portion 2 at the split end of the split core 1 is held between the chucks 3. Then, the flyer 5 is wound around the yoke part 4 of the slot S1 , and the electric wire 6 is wound around it. A winding guide 7 is provided outside the orbit of the electric wire 6 in order to prevent the electric wire 6 from coming into contact with the tooth tip 8 and breaking the wire when passing through the slot opening.

ない。 When the winding in slot S 1 is completed and the winding is to be moved to slot S 2 , the iron core 1 is rotated about its center in the direction of the arrow. As it protrudes, it collides with the winding guide 7 and the split core 1
It is not possible to rotate chuck 3 and position it.

さいガイドと差し替えて巻線を続行し、最後のス
ロツトは前記の方法に頼つて巻線する。 Normally, the winding guide 7 is removed at this point,
When the slot to be wound is the slot closest to the dividing surface, the tip of the chuck 3 is made large and used as a guide to wind the wire in the slot.
Furthermore, if the slot to be wound is not the slot closest to the dividing surface, the above-mentioned combination cannot be achieved, and the winding is continued by replacing it with a smaller guide, and winding the last slot by relying on the above-mentioned method.
従つて巻線作業中にガイドを取替えたり、取り
はずしたり余分な工程が必要で、巻線作業性が極
めて悪くなる。 Therefore, extra steps such as replacing or removing the guide are required during winding work, resulting in extremely poor winding work efficiency.

Since burrs are likely to be generated near the protrusion, the protrusion 10
As shown in Figure 3, the bottom surface 11 of
On the other hand, at the outer periphery of the dividing surface on the opposite side, a straight portion 12 is provided inside the outer periphery tangent by β.

後述する。 When the core shaped like this is joined and the annular shape is restored, it becomes as shown in Figure 4, and the outer periphery of the dividing surface and the protrusion 1
0, a cavity 13 is formed between the two. That is, the distance 1 from the center of the core to the bottom surface 11 of the protrusion 10 is larger than the outer radius R of the core. The effect of this cavity 13 will be described later.
第３図の鉄心１に巻線する場合を説明する。 The case of winding the iron core 1 shown in FIG. 3 will be explained.

た格好でセツトされている。 In FIG. 5, the entire protrusion 10 of the iron core 1 is held by hooking the chuck 3 on the bottom surface 11 of the protrusion 10. With the winding now completed on the yoke part 4 of the slot S 1 , rotate the iron core 1 in the direction of the arrow with the flyer 5 and the winding guide 7 as they are and the chuck 3 as the rotation center. When this happens, the state shown in FIG. 6 is reached, and the next winding to the slot S2 becomes possible. The winding guide 7 is set so as to protrude relatively from the iron core so that the chuck does not hinder its movement as in the conventional case.

が適当である。 Furthermore, if the core is formed to have the cavity 13 shown in FIG. 4 as described above, after winding is completed, the annular shape of the core is restored, wire connections and lead wires are attached, and then resin molding is performed. When forming the stator using
An outlet bushing for protecting the lead wire from the mold can be attached using this cavity 13. For this purpose, the cavity 13 needs to have a certain size, and in our experiments α = 2 to 0.5 mm,
β = 0 to 0.5 mm, width of cavity (α + β) = 1 to 2 mm
is appropriate.
