Abstract:
A method for manufacturing a stator of a rotary electric machine including a cylindrical stator core with a plurality of conductor segments respectively disposed in said slots in a plurality of radially aligned layers, said method comprising:forming a plurality of conductor segments each having at least a straight leg that has a grip portion at an end thereof; inserting said plurality of conductor segments into each of said slots in a plurality of radially aligned layers so that said straight legs can extend outside an end of said stator core and so that said grip portions of those of said straight legs disposed in a radially more outside layer are higher than grip portions of other straight legs; stratifying said straight legs in radially aligned layers, to correspond to said layers in said slots; holding each of said stratified straight legs at said grip portions; circumferentially shifting each of said grip portions of said straight portions relative to other portion thereof disposed in said slots in a prescribed circumferential direction of said stator core; and shifting each of said grip portions in an axial direction of said stator core to a position adjacent to another grip portion to be connected to each other.
