摘要： 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

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for the winding of a rotary electric machine wherein junction failure is prevented from occurring.
SOLUTION: The manufacturing method involves a pressure applying process in which the tips 331g and 332g of segment conductors with insulating covering stripped off are deformed, an inserting process in which the segment conductors with the tips 331g and 332g deformed through the pressure applying process are inserted into slots in a stator core, a bending process in which the ends of the segment conductor inserted into the slots are bent, and a joining process in which the joining portions 331h and 332h of the tips of the adjoining bent segment conductors are joined with each other. In the pressure applying process, the tips 331g and 332g are sandwiched from both sides in the direction of pressure application and deformed using a die having a pressure applying face which protrudes as it goes toward the end faces of the tips 331g and 332g and a punch having a pressure applying face opposed to the die.

摘要： PROBLEM TO BE SOLVED: To assure insulation between electrical conductors at a coil end. SOLUTION: One set of electric conductors 331a and 331b at a coil end 31b are so disposed as to cross the other set of electric conductors 332a and 332b radially adjoining at one or more points. Radial recesses 331g, 331h, 332g and 332h which deepen as proceed toward the ends of one electrical conductors 331a and 331b are formed on the side surface opposed to the other electrical conductors 332a and 332b at one of the intersections. Thus, the gap from other electrical conductor is sufficiently assured at the intersection near the end part where an insulating film is easy to be damaged by the heat at welding, resulting in assured electrical insulation, while the cooling characteristics at the coil end is improved.

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. A deformation part at the tip of one electric conductor is so deformed as to radially approach, in the direction, where the tip of the other electric conductor to be jointed is arranged, in a deformation 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 for manufacturing a stator coil of a rotary electric machine capable of surely constraining the axial position of a conductor regardless of the position of a lead wire. SOLUTION: A segment presser tool 116 used in a twist process for manufacturing a segment conductor that is inserted into each slot of a stator core comprises a fixed top plate 132 for pressing each turn of the segment conductor circumferentially arranged side by side in U-shape in the axial direction, and a mobile top plate 120 which closes a notch 130 formed at a part of the fixed top plate 132. The mobile top plate 120 circumferentially moves to close the notch 130 after a long profile segment conductor 333 for a lead wire is inserted in the notch 130, to constrain the axial position of each turn of segment conductors other than the profile segment conductor 333 disposed at a position corresponding to the notch 130.

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

摘要： PROBLEM TO BE SOLVED: To provide a rotating electric machine which can suppress the drop of the electric insulatability of an insulating sheet by the axial insertion of a coil conductor, and its manufacturing method. SOLUTION: The coil conductor is fitted in a roughly prismatic insulating sheet 3 which is stored in a slot 2, with its axial ends projected from the slot 2. The insulating sheet 3 has angles 31-34 in contact with the corners of the slot 2, and flat planes 35-38 extended in roughly parallel with the inner surface of the slot 2 from the angles 31-34, and the circumferential width of the coil conductor is larger than the circumferential width w' of the insulating sheet 3. Therefore, the planes 35-37 of the insulating sheet 3 are compressed by the insertion of the coil conductor, and the angles 31-34 of the insulating sheet 3 are pressed strongly to the corners of the slot 2, which prevents the insulating sheet 3 from being dislocated by the insertion of the coil conductor, thus the drop of the electric insulatability of the insulating sheet 3 due to the dislocation can be suppressed.
