絶縁不良が問題と成る。これは、スロット内へ挿入され
たコイルがスロット端面付近で所定の角度に捻られる為
にコイルがＣ形状等の開口部を大きく押し広げ電機子鉄
心とコイル間で絶縁不良が発生ずるためである。Among these, the S shape has excellent insulation properties, but has the problem of (2) high material and processing costs. Further, although the S10 shape is low in cost, it poses a problem of poor insulation, especially poor insulation at the end face of the throttle. This is because the coil inserted into the slot is twisted at a predetermined angle near the end face of the slot, which causes the coil to widen the C-shaped opening, etc., resulting in poor insulation between the armature core and the coil. .
本発明は上記の問題点に鑑み、コストの安いＣ形状の絶
縁紙を採用しながら、絶縁不良をおこすことのない回転
電機の電機子を得ることを目的とするものである。In view of the above problems, it is an object of the present invention to provide an armature for a rotating electric machine that does not cause insulation defects while employing C-shaped insulating paper that is inexpensive.

心１とを確実に絶縁する。- The upper layer coil 4 and the lower layer coil 5 are first twisted in opposite directions at the end face of the slot 2, but at this time, the slot end face portion 4 of the coil is bent toward the opening 3a.
a, 5a are pressed against the wide portion 3al of the insulating paper 3. Therefore, the wide portion 3al of the insulating paper 3 reliably insulates the coil and the iron core 1.

る。As described above, in the present invention, the opening (3a) of the insulating paper (3) is not formed in a straight line along the axis (X-X) of the slot (2), but is provided so as to be inclined. 3)
A wide part (3al) and a narrow part (3a2> are formed on the side surface of the opening (3a), and the slot end face of the upper and lower layer coils (4, 5) is formed on the opening (3a) side. Since the side surface of the coil that is bent is insulated from the iron core (1) at the wide portion (3a2), the opening (3a) is widened by bending the coil, and the coil ( 4, 5) and the iron core (), which has the excellent effect of preventing short-circuit accidents.In addition, this has the advantage of increasing costs. Therefore, the present invention is advantageous.
