摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing the coil of a rotary electric machine, capable of surely preventing the occurrence of poor jointing, by only adding a process of simple contents. SOLUTION: A plurality of electric conductors are inserted in slots formed at a stator core, in an inserting process.

The electric conductor inserted in the slot is bent, in a bending process. The tips of the bent electric conductors, adjoining each other, are jointed together, in a jointing process. The deformation process includes a thin-plate inserting process, where thin plates 350 and 352 are inserted between the electric conductors to be jointed, adjoining radially, except for the deformed parts, and a pressuring process for pressuring the deformed part in radial direction toward the side where the thin plates 350 and 352 are disposed, using a deforming tool 360.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing the stator coil of a dynamo-electric machine, which is can be manufactured in a simple manufacturing process. SOLUTION: To evolve the head of a segment 1000 for an interphase connection cable in the circumferential direction, this head is pre-twisted by one slot pitch in circumferential direction in advance, and also twisting of the top of this head is prevented. Then, the feet of several segments are evolved all at once in circumferential direction, by rotating rings 11 and 12 by half a magnetic pole pitch in the reverse direction, while holding the tops of the heads of the several segments. Hereby, the evolution of the heads can be performed in a simple process. COPYRIGHT: (C)2003,JPO
