Patent ID: 6862796

Claim:
A method for manufacturing an electric rotary machine including a winding and a core, said winding consisting of a plurality of conductor segments, each comprising a V-shaped head conductor portion and a pair of straight conductor portions extending from both ends of said V-shaped portion, which are covered by an insulating film and successively joined at distal ends of said straight conductor portions, and said core comprising a plurality of slots arrayed at predetermined angular intervals in a circumferential direction for accommodating said conductor segments, each of said slots having an axially near-side opening through which said straight conductor portion is inserted into said slot and an axially far-side opening from which the distal end of said straight conductor portion protrudes, so that said V-shaped head conductor portion of each conductor segment is held at one side of said core where said axially near-side opening is provided and protruding portions of said straight conductor portions are held at the other side of said core where said axially far side opening is provided, said manufacturing method comprising: an accommodating process for accommodating said straight conductor portions of each conductor segment into different slots so that at least part of each straight conductor portion extends as an exposed straight portion out of the slot from either said axially near-side opening or said axially far-side opening by a predetermined length, a twist shaping process for twisting said protruding portions of said straight conductor portions into tilt portions inclining in the circumferential direction, a shifting process for retracting said straight conductor portion into said slot from one of said axially near-side opening and said axially far-side opening after finishing said twist shaping process so that at least part of said exposed straight portion remains as one exposed straight portion having a first length and at the same time protruding the other side of said straight conductor portion out of said slot as another exposed straight portion having a second length from the other of said axially near-side opening and said axially far-side opening, thereby leaving said one and another exposed straight portions at both said axially near-side opening and said axially far-side opening of said slot.
