Patent ID: 8225484

Claim:
A method of manufacturing a stator for an electric rotating machine, the method comprising the steps of: (a) preparing a hollow cylindrical stator core and a plurality of electric wires, the stator core having a plurality of slots that are formed in a radially inner surface of the stator core and spaced in a circumferential direction of the stator core; (b) assembling together the stator core and the electric wires; (c) welding corresponding pairs of the electric wires to form a stator coil, wherein for each corresponding pair of the electric wires, one of the electric wires has an end portion led out from a radially inner periphery of one of the slots of the stator core while the other electric wire has an end portion led out from a radially outer periphery of another one of the slots of the stator core, the end portions of the electric wires are radially bent toward each other so as to have distal end surfaces of the end portions abutting each other at a position axially outside an annular coil end part of the stator coil, the coil end part protruding from a corresponding axial end face of the stator core so as to be located outside the slots of the stator core, the distal end surfaces of the end portions of the electric wires are welded together to form a weld between the end portions, and the end portions of the electric wires together make up a crossover part that includes the weld and extends to cross over the annular coil end part of the stator coil from the radially inside to the radially outside of the coil end part; and (d) deforming, for each corresponding pair of the electric wires, the end portions of the electric wires so as to reduce an axial distance between the coil end part of the stator coil and the crossover part made up of the end portions.
