Manufacturing method for a wound stator of a rotary electric machine

摘要

A method for manufacturing a winding (31) for an electric rotating machine (1) includes steps of altering, passing, shaping, and connecting. In the altering step, connecting portions (331d, 331d', 331e, 331e', 332d, 332d') of conductor segments (331, 332), a part of which is exposed, are altered in shape by a pressing die (100, 102, 100a, 102a) to provide good contact between the segments (331, 332) when they are connected. The altered segments (331, 332) are passing through slots (35) of a stator core (32) in the passing step. Ends of protruded portions of the segments (331, 332) are shaped so that they make an angle with respect to the radial section of the stator core (32) in the shaping step. Adjacent segments (331, 332) are connected together at ends of the connecting portion (331d, 331d', 331e, 331e', 332d, 332d') in the connecting step. <IMAGE>
