である。However, in the above configuration, since the armature coil can be further mechanically pushed into the slot after the armature coil is inserted into the slot, an unreasonable force may be applied to the armature coil, and sometimes the wire breaks or breaks. Insulation failure may occur. Further, if the force to be pushed in is weakened, the armature coil will stick out from the opening of the slot, and a correction process will be required, resulting in an increase in the number of work steps. It is an object of the present invention to reduce the number of working steps and increase the coil space factor of the slot by allowing the armature coil to automatically go deep into the slot during winding.

FIG. 1 is a side sectional view showing an embodiment of the present invention, and FIG. 2 is a front view thereof showing an iron core piece 2 punched from a disk-shaped thin steel plate and provided with a plurality of slots 1 at equal intervals along the outer circumference. The armature core 3 is formed by laminating the armature coils 3 into a predetermined stacking thickness, and the armature coil 4 is inserted into the slot 1. Armature core 3
In order to guide the armature coil 4 to the slot 1, a guide plate 5 having a slot 51 having the same shape as the iron core piece 2 is closely attached to both end faces of the shaft hole 31 provided at the center together with the armature core 3. The shaft 6 is fixed to 52. In the tooth portion 53 formed between the adjacent slots 51 of the guide plate 5, the inclined portion 54 is formed such that the thickness decreases from the outer circumference to the center of the tooth portion 53 at the bottom of the slot 51 toward the center. Has been formed. In this state,
As shown in FIG. 3, when the electric wire 7 is inserted into the slot 1 by the winding machine 6, the electric wire 7 receives axial tension on the end face side of the armature core 3, but the electric wire 7 is applied to the electric wire 7 by the tension acting on the electric wire 7. Generates a component force toward the center along the inclined portion 54 of the guide plate 5. Due to this component force, the electric wire 7 moves while sliding along the inclined portion 54, and is automatically pushed into the bottom of the slot 1, and by repeating a predetermined winding, the armature coil 4 packed deep in the slot. Is formed. FIG. 4 is a side cross-sectional view showing a second embodiment. As shown in FIG. 5, the tooth portions 21 of the two or three iron core pieces 2 are inclined in the axial direction from both end surfaces of the armature core 3. The inclined portion 22 is formed by pressing and bending with a punch P having a concave portion and a die D having a convex portion. This configuration does not require a separate material for the guide plate, which reduces costs. FIG. 6 is a side sectional view (a) and a front view (b) of a main portion showing a third embodiment, in which both sides of the teeth portion 21 of the second embodiment shown in FIG. The teeth portion 21 is formed so as to be in close contact with each other and the outer peripheral side projects in the axial direction to form the inclined portion 22 toward the root.
The bulging portion 23 is provided in the central portion of the. With this configuration, both sides of the tooth portion 21 are in close contact with the end surface of the armature core 3, and the shape of the inclined portion 22 is stable. FIG. 7 is a perspective view showing a fourth embodiment in which the teeth portion 53 of the guide plate 5 is provided at the axial end portion of the insulator 8 to be inserted into the slot 1, and at the same time the armature coil 4 is insulated. The space factor can be improved.
