Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a flat-sided fan-shaped winding body, which is suitable for an armature winding of a rotating electric machine.

There are flat armatures that use printed wiring by etching, etc., but this has a limit on the number of conductors and is unsuitable for motors driven by high voltage and low current. There are many drawbacks.

Various wire-wound type armatures have been proposed to solve this problem, but in general, a Kohei type armature as shown in FIG. 12 is constructed by combining a plurality of unit coils 13 as shown in FIG. 10. It consists of The unit coil 13 shown in FIG. 10 is made by winding the coil wire E in the gap 2 of the conventional pick-up device in the same 0 turns. It is formed.

However, if the gap is set to be close to that of the coil wire E, when the coil wire is inserted into the gap 2, the coil wire will hit the surface direction regulating pick-up opening, the green gap insertion groove of C, and the coil wire will not be inserted. The disadvantage is that the insulating layer may peel off. In order to solve this problem, it is possible to increase the gap length, but in this case, a tension T is applied to the coil wire E only in the direction orthogonal to the horizontal direction regulating jig A, and the surface direction regulating jig opening, Since the vector component of the tension in the direction orthogonal to C is zero, the unit coils have the disadvantage of poor alignment in the plane direction. The present invention was invented in view of the above points, and first, the basic principle of the present invention will be explained based on FIGS. 2 to 5.

Reference numeral 1 is a radial direction regulating jig, and on its circumferential surface, a single surface direction regulating pick 2 is movable to a plane x perpendicular to the circumferential surface and a conical surface Y inclined at a minute angle of 6 with respect to the plane. establish.

This surface direction regulating pick 2 is fixed in a conical state, and a third
As shown in the figure, the coil wires 3 are wound concentrically in alignment. At this time, since tension T is applied to the coil wire 3 in 6 angular directions with respect to the perpendicular line, in addition to the vertical component force, a horizontal component force is also generated, and each coil wire 3 is brought into close contact with the conical bidirectional regulating feeder 2. It is in. That is, the conical coil winding body 4' formed by winding the coil wire is equivalently shown in FIG. Then, when the bidirectional regulating jig 2 is displaced from the conical state to the planar state, the coil winding body 4 becomes a planar shape facing the planar direction regulating odor pickup 2, as shown in FIG. 5, and is aligned in both directions. become something. The present invention is based on this principle, and an example thereof will be explained with reference to FIGS. 6 to 12.

In this embodiment, a trapezoidal unit coil is formed, and the radial direction regulating pick 5 is in the shape of a broken trapezoid, and four plates 7 as the planar direction regulating pick 6 are provided on the four sides of the trapezoid of this pick. is jig 5
A horizontal plane 8 perpendicular to the vertical side surface of the board 7 and a conical surface 9 inclined at a minute angle 6 with respect to the plane are movably provided, and the side surface of each plate 7 on which the sling 5 is attached has an inclined surface 101. ing. Then, the surface direction regulating jig 6 is positioned in a conical shape, that is, the inclined surface 10 of each plate 7 is in close contact with the vertical side surface of the flea direction regulating odor pick-up 5, and the coil wire 11 is arranged around the pick-up tool 5. A conical coil winding body 1 is arranged and wound in the same 0 shape on a coin-shaped pick-up tool 6.
form 2.

A perspective view of this coil-wound body is shown in FIG.
A cross section is shown in FIG. After forming this conical coil winding body 12, the plate 7 of the planar direction regulating jig 6 is displaced into a plane perpendicular to the circumferential surface of the radial direction regulating jig 5 as shown in FIG. The shaped coil wound body 12 is flattened.

In this state, the adjacent coil wires 11, 11 are fixed by appropriate means. In the embodiment, a unit coil 13 is formed by applying a self-fusing conducting wire as the coil wire 11 and fixing adjacent coil wires 11, 11 together by applying alcohol. A perspective view of this unit coil 13 is shown in FIG. 10, and a BB cross section thereof is shown in FIG. 11. As shown in FIG. 12, the plurality of unit coils 13 are sequentially arranged and fixed in an annular manner on an insulating substrate 14 in a staggered manner to constitute a fan-shaped winding body of an armature 15. 1
6 is a commutator, and each segment has a unit coil 1.
No. 3 lead-out IJ-do wire 17 is connected.

As described above, according to the present invention, it is possible to form a planar unit coil which is wound in a uniform zero pattern in the plane direction without destroying the insulating layer of the coil wire. When unit coils are sequentially shifted and arranged in a ring to form a fan-shaped winding body, since each unit coil is aligned in the plane direction, the thickness of the fan-flat winding body can be reduced.
