スロット４，４間を塞ぐような状態となる。Page 2 Conventionally, slot insulators that are generally used in machine-wound coils are manufactured by bending the end of an insulator 1 to form a cuff 2, and then performing a U-bending process L, as shown in FIG. As shown in the figure, it is inserted into a slot 4 provided in the iron core 3. However, in this conventional slot insulator, due to the springback caused by the bending and U-bending of the cuff part 2, the end of the insulator l and the cuff part 2 fall to the outside of the slot wall, as shown in FIG. This results in a state in which the adjacent slots 4 are closed.

問題が発生する。In addition, when the coil 5 is inserted into the slot 4 in which the slot insulator is installed, the end of the insulator and the cuff 2 are further pushed to the outside of the slot 4 due to the coil end being pulled or bulging. In cases where the slot in-slot conductor space factor is high or the coil end circumference is short, the slot insulator collapses significantly, resulting in the following problems.

いは径方向に変形することもある。■ At the point where the slot insulator comes into contact with the edge formed by the end face of the core 3 and the wall of the slot 4, there is a load due to the insertion of the coil 5 and the wedge 6. By concentrating, the number 1 in FIG. 4 of the slot insulator
The area marked ' is severely damaged, resulting in poor insulation. Furthermore, the end face portion of the iron core 3 around the slot may be deformed in the axial direction or the radial direction.

■ スロット絶縁物の端部の倒れに伴い、コイルエンド
と鉄心３間の絶縁に、必要な距離を確保できなくなる。■ Due to the collapse of the end of the slot insulator, coil bulges and coil crosses occur near the end of the slot 4 during the coil insertion process, reducing the ease of inserting the coil 5 and wedge 6. In addition, as shown in Figure 5, the wedge 6 may be inserted inside the coil, causing insulation failure. ■ As the end of the slot insulator collapses, it becomes impossible to secure the necessary distance for insulation between the coil end and the iron core 3.
■ コイルエンド部全結束するための糸かけ作業の前に

保持治具全効果的に利用することができなかった。As a countermeasure to the above problem, adjacent slots 4
．． It is effective to insert a holding jig to hold the end of the slot insulator along the side wall of the slot 4 between the slots 4 during the coil insertion process or the coil forming process. Since the space between the slots 4, 4 is closed by the cuffs 2, 2, this becomes an obstacle, and the holding jig cannot be used fully.

合がある。- Therefore, if the cuff part 2 is not provided at the end of the insulator 1, the above problem can be solved, but if the cuff part 2 is not provided, the movement of the slot insulator in the axial direction cannot be restricted. Moreover, there is a problem in that the strength of the end portion of the slot insulator is also reduced.

が低下する。(2) When U-bending slot insulators, compressive stress and strain are generated inside the bent portion, while tensile stress and strain are generated outside the bent portion, and bending workability decreases as the wall thickness increases.
特に、曲げ半径が端部の肉厚に対応する最小曲げ半径よ

As a result, it is possible to easily and accurately insert coils and wedges, which greatly reduces the number of man-hours required for rework due to incorrect insertion of these parts, and increases the conductor space factor in the slot. Even when inserting something tall or with a short coil end, deformation and damage to the ends of the slot insulator and the core can be prevented, and insulation defects can be completely prevented. Further, since the void portion can be secured, the cooling characteristics of the coil and the iron core can be improved.
