## Abstract

An assembly conducting wire for a rotary electric machine winding includes a plurality of bundled wires, the plurality of wires being twisted in a circumferential direction of the assembly conducting wire, and the plurality of wires being welded together at a predetermined distance.

## Claims

### Claim 1

An assembly conducting wire for a rotary electric machine winding, comprising:
a plurality of bundled wires, the plurality of wires being twisted in a circumferential direction of the assembly conducting wire, and the plurality of wires being welded together at a predetermined distance.

### Claim 2 (depends on 1)

The assembly conducting wire according to claim 1, wherein the predetermined distance is a distance at which the plurality of wires are twisted 180 degrees in the circumferential direction of the assembly conducting wire.

### Claim 3 (depends on 1)

The assembly conducting wire according to claim 1, wherein the predetermined distance is a distance at which the plurality of wires are twisted 360 degrees in the circumferential direction of the assembly conducting wire.

### Claim 4

A rotary electric machine comprising:
a stator;
a rotor; and
an assembly conducting wire including a plurality of bundled wires, the plurality of wires being twisted in a circumferential direction of the assembly conducting wire, and the plurality of wires being welded together at a predetermined distance, the assembly conducting wire being wound around the stator or the rotor such that a welded portion of the assembly conducting wire is positioned inside of a slot of a stator core of the stator or a slot of a rotor core of the rotor.

### Claim 5 (depends on 4)

The rotary electric machine according to claim 4, wherein the predetermined distance is a distance at which the plurality of wires are twisted 180 degrees in the circumferential direction of the assembly conducting wire.

### Claim 6 (depends on 4)

The rotary electric machine according to claim 4, wherein the predetermined distance is a distance—at which the plurality of wires are twisted 360 degrees in the circumferential direction of the assembly conducting wire.
