Description

Description: TECHNICAL FIELD The present invention relates to an armature winding of a rotating electric machine, and particularly to a material and a material which are used for insulation work using an insulation tube of a crossover without lowering insulation reliability. The present invention relates to an armature winding of a rotating electric machine suitable for reducing man-hours.

[Prior Art] Regarding conventional technology, three-phase four-pole A description will be given with reference to FIG. 21 and FIG. 22 of an example of an armature winding of a stator having a connection, a two-stage / one-stage concentrically wound coil, and 36 slots.

In FIGS. 21 and 22, numerals 1 to 36 in the drawings indicate slot numbers. In FIG. 22, a solid line indicates a U-phase winding, a broken line indicates a V-phase winding, and a two-dot chain line indicates a W-phase winding. Reference symbol S in FIG. 21 indicates a stator core.

That is, in this armature winding, a U-phase winding, a V-phase winding, and a W-phase winding are arranged at different positions along the radial direction for each phase on the end face of the stator core S. A plurality is provided concentrically adjacent to each other.

The winding of each phase is composed of a two-stage wound coil × 2 sets and a one-stage wound coil × 2 sets.
Lead wires U t , V t , and W t are respectively drawn from one of the two-stage winding coils, and a crossover U reaching a neutral point from one of the two-stage winding coils.
l , V l , and W l are extracted.

The winding of each phase is composed of an enamel-coated insulated wire, but in order to ensure insulation reliability against a potential difference from a winding of a different phase, a film (for example, 0.18 mm polyester film) -shaped interphase insulator I p is used. Mounted between the coils.

The coil-to-coil interphase connection portion C has a neutral point connection portion N,
Connecting wire U l, V l, W l , insulation tube T u, T v, consists T w and the insulating coating I n.

The neutral point connection portion N is connected by means such as soldering, welding, fusing (thermocompression bonding), or compression bonding.

Insulating coating I n the tube (e.g., a varnish tetronic tubes or polyester tubes), a tape, or the insulating material such as film is used, FIG. 21 and the
Since an insulating tube is used in the example shown in FIG. 22, the structure shown in the drawing is used to secure a space distance and a creepage distance on the insulation of the neutral point connection portion N with respect to the coil.

The crossovers U l , V l , and W l are flexible bodies and their shapes are indefinite, and the path from the pull-out position to the connection position between the coil phases is not generally restricted in terms of insulation work. Therefore, since the crossovers U l , V l , and W l abut against the out-of-phase coils, from the viewpoint of ensuring the reliability of inter-phase insulation,
Cover the crossover lines U l , V l , and W l with insulating tubes Tu , T v , T w (for example, a wanistetron tube or a polyester tube), and cover the portions covered with the insulating tubes Tu , T v , T w. by placing on the coil is inserted into the insulating coating I n as shown superimposed parts, and so as to reinforce the insulation.

Further, the crossover lines U l , V l , W l and the coil phase connection portion C are
It is bound and fixed together with the coil by means such as racing or taping (not shown).

On the other hand, as another conventional example in the insulation work of the crossover,
There is a technique described in Japanese Utility Model Laid-Open No. 53-51901. In this conventional example, the path of the crossover to the in-phase coil is specified, and is applied only to the crossover of the outermost coil as viewed from the axis of the stator.

However, in the conventional example described in Japanese Utility Model Application Laid-Open No. 53-51901, no consideration is given to the path of the crossover to the different-phase coil.

[Problems to be Solved by the Invention] In recent years, winding work of a rotating electric machine has been automated, but connection and insulation work of a crossover wire and a lead wire in a subsequent process mainly depend on human labor.

In particular, the operation of inserting the insulation tube in the insulation work of the crossover wire is difficult to automate because the crossover wire is a flexible body and its shape is uncertain, which has been a bottleneck in the production of armature windings.

On the other hand, the conventional example described in Japanese Utility Model Publication No. 53-51901,
Although the operation of inserting the insulating tube is partially omitted by specifying the path of the crossover to the in-phase co-oil, the path of the crossover to the out-of-phase coil is not considered and is insufficient.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems of the prior art, to reduce the materials and man-hours involved in the insulation work using the insulation tube of the crossover without reducing the insulation reliability, and to reduce the size and temperature characteristics of the rotating electric machine. It is an object of the present invention to provide an armature winding of a rotating electric machine which can improve the power consumption.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, an insulating coating is disposed on any one-phase coil, and one end of the insulating coating is made the same as the coil. Positioned at a position between in-phase coils adjacent on the circumference, at least of the crossover wires drawn from each phase coil, at least a crossover wire from a different-phase coil adjacent to the coil on which the insulating coating is arranged is located at the portion. An inter-phase insulator between the hetero-phase coil and the one-phase coil is inserted into the insulating coating from one end thereof while the insulator is not mounted, and a neutral point connecting portion in the insulating coating is inserted. And the one-phase coil-side connecting wire on which the insulating coating is arranged is inserted into the insulating coating without attaching an insulator, and a neutral point connection portion in the insulating coating is provided. Connected to It is characterized by the following.

[Action]

As described above, at least the crossover wires from the one-phase coil in which the insulating coating is arranged and the adjacent-phase coil are adjacent to each other. The crossover wire on the one-phase coil side, which is inserted into the insulating coating from one end thereof and connected to the neutral point connection portion in the insulating coating while the insulating coating is not disposed, is also provided. Is inserted into the insulation coating without the insulator attached, and is connected to the neutral point connection portion in the insulation coating, whereby at least the crossover wire drawn from the two-phase coil is connected to the insulation tube. Since there is no need to attach the insulation coating of the coil phase connection part to the insulation tube of the crossover, it is not necessary to configure the insulation coating of the coil phase connection part as compared with the conventional technology, and the size of the coil phase connection part can be reduced accordingly. Kill result, it is possible to reduce the size of the rotary electric machine, yet it is possible to improve the temperature characteristics.
