Abstract
A method for manufacturing a winding for an electric rotating machine includes steps of altering, passing, shaping, and connecting. In the altering step, connecting portions of conductor segments, a part of which is exposed, are altered in shape by a pressing die to provide good contact between the segments when they are connected. The altered segments are passing through slots of a stator core in the passing step. Ends of protruded portions of the segments are shaped so that they make an angle with respect to the radial section of the stator core in the shaping step. Adjacent segments are connected together at ends of the connecting portion in the connecting step.
