両到である。The dotted lines in FIG. 1 indicate the sides of the coils inserted into the upper side (Sekiguchi side) of the slots, the solid-line arcs in FIG. 2 indicate the coil ends of each coil, and the black dots indicate the coil sides. That is, first slots 1, 2, 3 and 10, 1
Insert the first U-phase coil U into 1 and 12. Next, the third coil U3 of the U phase is placed in the slots 13, 14, 15.
and 22, 23, 24, and a second U-phase coil U.
2 into slots 25, 26, 27 and 34, 35, 36
Then, the fourth coil U4 is inserted into the slots 37, 38, 39 and 46, 47, 48. Next, shift each V-phase coil by 60 electrical degrees from the U-phase, and insert the 1st coil, 3rd coil, 2nd coil, and 4th coil into their respective slots in the same way as the U-phase. , W-phase coils are similarly inserted by sliding them 60 degrees electrically from the V-phase. However, in this bag-wrapping method, the U-phase, V-phase, and W-phase coils can be inserted in order from the bottom (back side) to the top (opening side) of the slot, so the coil insertion process is easy. However, the coil ends are completely separated into the inner, middle, and outer parts for each phase, and the coil ends become large and there is no gap between them, and the cooling from the internal cooling fan that can be Due to poor wind permeability, the W phase, where the coil end is on the inside, is well cooled by the cooling air from the internal cooling fan, but the U phase, where the coil end is on the outside, and the V phase, where the center part is.
The cooling air does not reach the phase well, and the cooling air itself absorbs heat from the inner coil end and has heat, so it is not cooled sufficiently and the cooling of the entire armature winding becomes unbalanced, causing the coil to Since the stator core is wound in layers, the stator core must be rotated three times during the winding process, making the work extremely time-consuming.

and insert it into this U. Insert the coil W, which is shifted by 120 electrical degrees from the coil, into slots 9, IQ, 11 and 18, 19, and 20', and similarly insert the coils V3, U2, W2, and V4, which are shifted by 120 degrees, respectively. As a second step, the first coil U of the first step,
It has been proposed that each phase coil U3, W3, V2, U4, W4, V of opposite polarity is similarly inserted on top of the coil inserted in the first step from a position 180 electrical degrees shifted from . However, the stator core can be rotated twice during the winding work, but the coil ends are in two stages, and the coil to be wound in the second step has slots 13 on one side like the U3 coil. , 14, 15, and the other side is the lower coil of the slots 22, 23, 24, while one side of the coil W is the lower coil (slots 18, 19, 20).
) and one side of coil V3 is the upper coil (slot 17,
18, 19), the coil ends intersect, resulting in a disadvantage that the shape of the coil ends becomes long and complicated.

エンドが相互に交叉しないように構成できる。First, both sides of the first coil U of the U phase are inserted into the lower sides of the slots 1, 2, 3 and 10, 11, 12, respectively. Next, the first coil of V phase adjacent to this coil U,
The coil V is placed in the slot 5 at a position shifted by 60 degrees in electrical angle.
, 6, 7, connect one side of the coil to the previous coil U. Insert the coil from above, and insert the other coil side under the slots 14, 15, and 16. Furthermore, the first coil W of the next W phase,
are similarly inserted into slots 9, 10, 11 and slots 18, 19, 2 which are shifted by 60 electrical degrees from the V-phase first coil V. After that, the third coil, second coil, and fourth coil of each phase are arranged in the order of arrangement, that is, U3→
In the order of V3 → W3 → U2 → V2 → W2 → U4 → V4 → W4, shift each coil by 60 electrical degrees from the previous phase coil, stack one side of the coil on top of the previously inserted coil, and insert it into the slot. Insert it into. and the fourth and final V phase
The coil V4 and the fourth W-phase coil W4 are connected to the slots 41 and 4.
2,43 and 2,3,4 and slots 45,46,47
and 6, 7, and 8, respectively, with both coil sides on the upper side (open □ side)
Insert it into the holder to finish wrapping. (Effects of the Invention) As described above, in the winding method of the present invention, when inserting the same wound coil into a slot, one pole of one phase is inserted first, and then the other phases arranged adjacent to it are inserted. The coils are inserted one after the other with one pole shifted by 60 degrees in electrical angle, overlapping the previously inserted coil, so the winding work is done by rotating the stator iron once. All the coils can be wound by rotating the coils by rotating the coils. The coil ends can be stacked diagonally above the slot so that they do not cross each other.
