DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a winding method for a winding used in a rotating electric machine such as an induction motor,
In particular, the present invention relates to a method of winding a winding for a rotating electric machine having interlayer insulation between wires.

For example, the winding of a rotating electric machine such as an induction motor generally includes a plurality of electric wires grouped together to form one turn. This is then wound into a wire with several turns in a predetermined shape, and interlayer insulation is provided between each turn. These wires are wound into various shapes depending on the purpose, but the most common winding method is the winding process in which the wire is wound around a rectangular winding die and formed. Thereafter, it is usually separated into an interlayer insulation process in which it is removed from the winding die, separated into pieces for each turn, and an insulating material is taped for each turn. However, in this process, interlayer insulation is applied to each separated winding, which requires a lot of man-hours and increases production costs. Therefore, there is an idea to perform interlayer insulation in the winding process.
That is, this is a wire winding method in which an insulating material is taped while the wire is in a straight state, and then the wire is wound on a predetermined winding form.

When using this method, multiple wires after interlayer insulation are wound around the winding die at the same time, so that among the multiple wires, the wires located on the inner circumferential side of the winding die and the electric wires located on the outer circumferential side are different. Since the circumferential lengths are different, that is, the wires on the inner circumferential side have slack, so smooth winding cannot be performed unless there is a misalignment between the inner wire and the outer wire. However, the wire bundle has already been subjected to interlayer insulation, and due to the tightening force of these insulating materials, it is difficult to cause smooth displacement between the inner wire and the outer wire within the interlayer insulation. Therefore, if the wire is wound around the winding form in this state, it will be wound around the winding form with the circumference of the wire on the outer circumferential side of the winding form inside the interlayer insulation, and the wire will be pulled out at the same length. The wire on the inner circumferential side is subjected to compressive force on the winding die, causing problems such as meandering edgewise or flatwise, and residual stress. Additionally, there was a drawback that the interlayer insulation was damaged due to the above-mentioned causes.

The present invention has been made in view of the above points,
Therefore, it is an object of the present invention to provide a method for winding an electrical device in which residual stress in the wire within the interlayer insulation is reduced when winding the wire provided with the interlayer insulation.

That is, in the present invention, after winding and insulating with an insulating material and before winding around a winding former, a circular drum having the same circumference as the winding former is placed between the insulating material taping device and the winding former. , and is provided adjacent to the taping device, and after preforming the electric wire by temporarily winding it around the circular deram, the electric wire is wound into a square winding form to achieve the above object.

One embodiment is shown in FIGS. 1 and 2. The wires 2 and 3 are pulled out from the wire drum 1 and collected on the guide roller 10 to form the wire bundle 8. After taping the insulation material 9 with the movable insulation material taping device 6, the wire bundle is leveled again with the guide roller 10. Hold. The wire bundle is then wound once around a circular drum 7 having the same circumference as the winding form 5 and located adjacent to the taping device, and after being preformed, the wire bundle is wound around the winding form 5, and this The winding die 5 is rotated by the winding machine 4 to wind the wire bundle into the expected shape. Here, FIG. 2 shows the details of temporarily winding the electric wires 2 and 3 on the circular drum, but the electric wire 3 on the inner circumference side of the drum and the electric wire 2 on the outer circumference side of the electric wire bundle temporarily wound on the circular drum are as follows. When the wire bundle is pulled out to the winding die side, when the thickness of the wire is t, a shift occurs between the wires 2 and 3 by a length of π×t for each rotation of the drum. After that, when the wire bundle with the above deviation is wound around the winding die, the inner and outer wires are smoothly shifted to match the circumferential length on the winding die, resulting in the winding having the expected shape. This allows the wire to be drawn with less residual stress.

In this way, if the amount by which the wire after interlayer insulation is shifted on the winding die is caused by temporary winding on a circular drum before being wound on the winding die, the wire will already be in the predetermined position by the time it is wound on the winding die. Since the amount of deviation occurs within the interlayer insulation, it is possible to smoothly wind the wire into a predetermined shape. Here, the amount of deviation needs to be equal to the amount of deviation on the winding form and the amount of deviation when tentatively wound on a circular drum, as described above. If this is different, the displacement of the wire inside the interlayer insulation will not be smooth, the wire will contain a certain amount of residual stress, and the interlayer insulation will be damaged, resulting in a decrease in the breakdown voltage value. Such problems will arise. Therefore, the circumference on the winding form and the circumference of the circular drum must be the same.

Furthermore, when shifting the inner and outer wires on the circular drum, it is important to do so within a relatively short distance of the distance taped with insulating material. If the taping distance is increased, the force used to shift the inner and outer wires will not only increase significantly, but also cause the wires to remain in place and stretch beyond the elastic limit of the wire's tension. This is because there are some difficulties. In this respect, since a circular drum is used in the present invention, a device for always applying curling can be provided at a position close to the taping distance, that is, a position close to the insulating material taping device.

As described above, the present invention provides a method in which a circular drum having the same circumference as the winding form is provided adjacent to the insulating material taping device after the insulating material is wound and insulated and before the winding is wound around the winding form.
