PROBLEM TO BE SOLVED: To provide a manufacturing method for the winding of a dynamo-electric machine and a forming method for winding recessed portion, wherein electrical insulation can be ensured between a stator core and electrical conductors. SOLUTION: The manufacturing method for the winding of a dynamo-electric machine comprises a pressing process, in which the pressed portions 331g of segment conductors are pressed in a predetermined direction to reduce the dimension thereof in the direction of pressing; an inserting process in which the segment conductors partly deformed in the pressing process are inserted into the slots in a stator core; a bending process in which the segment conductors are bent; a jointing process in which the ends of the segment conductors are jointed with each other. In the pressing process, a segment conductor is set in a die 100. The die 100 has arc-shaped corners 100a for suppressing deformation in the corners 331h of the pressed portion 331g located in the direction opposite to the direction of pressing. With the segment conductor set in the die 100, the pressed portion 331g is pressed by a punch 102. COPYRIGHT: (C)2004,JPO |
