必要とし、製造コストの面から不利であった。This type of stator coil for a rotating electric machine equipped with a stator and a rotor is formed by winding coil wire to form a hexagonal shape, and applying insulation treatment to the outer periphery to form a single coil. The appearance of the one fill is shown in a perspective view in FIG. The part indicated by 1 in one rail is the coil end, and the coil end straight part 1
a and a coil head 1b. The part indicated by 2 indicates a slot storage part, and the outer periphery of both the coil end 1 and the slot storage part 2 is subjected to insulation treatment 3. Slots 5 of stator core 4 shown in FIG.
To accommodate the VC coil, one fill of the delimiter coil is successively accommodated in such a manner that one slot accommodation portion 2 is placed at the bottom of the groove and the other slot accommodation portion 2 is placed above the groove of the other slot 5'. At this time, the coil is housed while adjusting the interval between the slot housing parts 2 of the stator coil according to the thread pitch, so that the distortion at the coil end 1
This had the drawback that the insulation treatment 3 of the head 1b was damaged due to the insulating treatment 3 of the head 1b being damaged. As a countermeasure for this, we fabricated a half coil (a shape in which the two heads of a single coil are separated) instead of encoiling the stator coil, and after storing the coil in the slot of the stator core, we installed the coil at the tip of the coil head. A method was adopted in which the coil wires were connected at the coil head and then insulated, but this half-coil method required a lot of man-hours to connect at the coil head, and was disadvantageous in terms of manufacturing costs. there were.

りとコイル頭部との外周を絶縁処理を施すようにした。The purpose of this invention is to eliminate the above-mentioned drawbacks and to configure a stator coil so that the insulation will not be damaged when the coil is housed even if it is a single coil. It was configured as follows. In other words, a release sheet is inserted between each coil wire layer extending between the straight part of the coil end and the coil head, and a gap is provided between each coil wire layer of the coil head, and a slot housing portion of the stator coil is inserted. After the stator coil, which has been previously insulated from the coil end to the straight part of the coil end, is housed in the slot of the stator core, the rest of the straight part of the coil end and the outer periphery of the coil head are insulated. .

The figure is an N-view M view of the coil end of a stator coil (one fill) that is an embodiment of the present invention, FIG. 4 is a cross-sectional view taken along line A-A in FIG. 3, and FIG. -B is a cross-sectional view. This stator coil is formed into a hexagonal shape by winding the coil wire 6 (in the illustrated example, 5 layers, 2 rows, 10 turns).
Seven release sheets (for example, Teflon sheets) are inserted between the layers of each coil wire 6, spanning between the straight portion 1a of the coil end and the coil head 1b. and coil head 1b
A gap 8 is provided between the layers of each coil wire 6, and insulation treatment is applied to the outer periphery of the fill wire 6 bundle from the straight portion 1a of the coil end to the slot housing portion.

Since there is a gap between the coil wire layers in bK, it is easy to move. After the stator coil in this state is housed in the slot of the stator core, the remaining straight portion of the coil end and the outer circumference of the coil wire bundle of the head 1b are insulated by a method such as wrapping with tape. did.

In addition, since the outer periphery is not insulated, it can withstand some deformation, making it easier to accommodate the coil. The head can be insulated after the coil is housed.
