Patent ID: 7302750

Claim:
A method of manufacturing an armature having a plurality of conductors inserted into slots formed around an outer periphery of an armature core, the method comprising: forming a plurality of conductors, each conductor having an in-slot portion and a pair of side portions extending straight from both ends of the in-slot portion, a bending portion having a thickness smaller than a thickness of the in-slot portion being formed between the in-slot portion and the side portion so that the conductor is easily bent at the bending portion; inserting conductors into the slots; bending the side portions of the conductors at the bending portions at substantially right angle so that the side portions are positioned substantially in parallel to axial end surfaces of the armature core; and skewing the side portions of the conductors by a predetermined angle relative to a radial line connecting a center of the slot and a center of the armature, wherein: the step of bending and the step of skewing are performed simultaneously after all of the conductors are inserted into the slots.
