Patent ID: 7287311

Claim:
A manufacturing method of a stator for a vehicular rotary electric machine including a stator core having a plurality of slots, and a multi-phase stator winding constructed of a plurality of electrical conductors connected together, said electrical conductors being accommodated radially side-by-side within said slots and electrically insulated from each other, and having ends extending to an outside of said slots and being bonded together to form a coil end, the method comprising: forming an indentation in a radial direction in a side face of each of the electrical conductors by pressing in such a manner that said indentation is disposed at least at one intersecting point between the adjacent electrical conductors; inserting said plurality of electrical conductors in a radially side-by-side relationship with each other in the slots; bending each of the electrical conductors and radially adjacent electrical conductors in different circumferential directions by a predetermined pole pitch such that the indentations formed in respective side faces of the adjacent electrical conductors pass each other in a face-to-face relationship; and bonding on each of each of said electrical conductors to one end of the adjacent electrical conductors, wherein said each indentation has a depth such that the depth increases toward one end of each electrical conductor.
