問題を有している。At the time of wedge driving, since a long wedge cannot be used for driving, as shown in FIG. However, even if the wedge is divided into appropriate lengths, it is still the same as driving in the length direction of the iron core, so that the longer the iron core length, the harder it is to wedge,
As shown in FIG. 4, there is a problem that the tip of the wedge is shaved due to friction with the iron core, and sometimes comes off the slot.

Reference numeral 5 denotes a wedge, which is formed of a plate having a rectangular shape that is long in the axial direction, and is provided with a notch that is bent from the center in the width direction. When the wedge 5 is inserted into the slot 2, as shown in FIG. 1A, the cut surface 51 formed by the cut is inserted outward from the coil 3 as indicated by a dotted line and bent. By hitting the bent portion, the wedge 5 becomes flat in the slot as shown in FIG. If an adhesive is applied to the cut surface 51 before the wedge 5 is inserted, the cut portion is bonded when the state shown in FIG. There is no escape from the slot. When the stator is integrally impregnated with the resin after the wedge is inserted, the wedge 5 is integrally fixed by the resin. In this case, it is not necessary to apply an adhesive.

That is, in this embodiment, the strength is increased by attaching a reinforcing member 6 made of a tape, a thin epoxi glass laminated plate, or the like from above the cut of the wedge 5, or by fixing with a resin impregnation.

縮される等の利点を有するものである。As described above, according to the present invention, a bent wedge having a cut is inserted from above a slot to form a bent portion instead of driving a wedge in the length direction from the end of an iron core as in the prior art. The wedges are flattened, so that the wedge ends are not cut off from the slots. In addition, the wedge is divided in the length direction,
Since it is not necessary to drive several grooves into the grooves, there is an advantage that the working time is shortened.
