Embodiment Construction

[0032] A preferred embodiment of the above-mentioned method of manufacturing a stator for a rotating electrical machine will be described.

[0033] In the above method of manufacturing a stator for a rotating electric machine, the outer peripheral end portion of the one conductor portion and the outer peripheral end portion of the other conductor portion refer to the yoke side when disposed on the outer peripheral side of the teeth of the stator core. the end of.

[0034] With respect to the stator core, the coils arranged on the teeth prior to the last coil can be arranged on the teeth of the stator core in order around the circumferential direction.

[0035] In addition, in the above-mentioned method of manufacturing a stator for a rotating electrical machine, the final coil may be formed by inserting a flat wire along the inner and outer sides along the shape of the teeth formed by the front-end parallel side, the middle inclined side, and the base-parallel side. It is for...

Abstract

The present invention provides a method of manufacturing a stator for a rotating electrical machine, which arranges a final coil (3C) that is finally arranged on a tooth (21) as follows. The final coil (3C) is deformed into a rhombus shape, and the outer peripheral end (321) of the one-side conductor portion (32A) is inserted into the one-side slot (22A). The outer peripheral end (321) of the one-side conductor portion (32A) is inserted into the boundary position between the middle inclined side (212) and the base-end parallel side (213) in the one-side groove (22A). The deformation of the final coil (3C) is restored, and the outer peripheral side end (321) of the other side conductor part (32B) is inserted into the middle inclined side (212) and the base end parallel side ( 213) boundary position. The one-side conductor part (32A) and the other-side conductor part (32B) are simultaneously inserted into the one-side groove (22A) and the other-side groove (22B), respectively.

Description

technical field [0001] The present invention relates to a method for manufacturing a stator for a rotating electrical machine by arranging a coil on a stator core. Background technique [0002] As a method of manufacturing a stator for a rotating electric machine, there are a method of arranging coils on a one-piece stator core, a method of arranging coils on split cores formed by dividing the stator core, and connecting the split cores on which the coils are arranged, etc. . In addition, the coil may be formed by intensively winding a plurality of thin magnetic wires, or may be formed by winding a single flat wire. [0003] For example, Patent Document 1 discloses a motor stator manufacturing apparatus in which a plurality of trapezoidal coils formed by bending a flat conductor having a rectangular cross section are inserted into a plurality of teeth in a stator core. This manufacturing apparatus has a coil shape restricting member for restricting the trapezoidal coil to ...
