摘要： Provided is a method of manufacturing a sequential segment joining type stator coil for use in an electric rotating machine, capable of achieving satisfactory electrical and thermal contact between end tip portion pairs of segments and basal electrodes and of realizing suitable welding even in the alignment of a large number of end tip portion pairs. For the arc welding of the end tip portion pairs of a sequential segment joining type stator coil, a large number of end tip portion pairs adjoining each other in a radial direction are held and pressed between basal electrode blocks. At this time, a circular-arc-like auxiliary electrode is put in a radial spacing between the end tip portion pairs. This not only enables the feeding to the end tip portion pairs lying at an intermediate position in the radial direction but also stabilizes the positions of the end tip portion pairs, and even reduces the heat radiation to an insulating coat of end skewing portions extending from the proximal portions of each end tip portion pair.

摘要： A tail side coil end includes a plurality of tail conductor pairs sequentially disposed with predetermined radial gaps. The radial gaps between the conductor pairs are widened in the vicinity of their tail joint portions compared with those in the vicinity of the end surface of a stator core. This arrangement effectively prevents adjacent tail joint portions or adjacent slanting portions from undesirably contacting with each other, thereby adequately maintaining electric insulation between the tail conductor pairs and also improving the space factor of the slot.

摘要： A stator for a dynamoelectric machine includes a stator core and a stator coil. The stator coil is made up of wave-shaped electric wires mounted on the stator core. Each of the electric wires has in-slot portions, each of which is received in one of slots of the stator core, and connecting portions each of which is located outside of the slots to connect one adjacent pair of the in-slot portions. Each of the connecting portions includes an apex part that is located axially furthest in the connecting portion from the stator core and includes an oblique section extending obliquely with respect to the radial direction of the stator core. Further, the oblique sections of the electric wires on one side of the stator core in the axial direction of the stator core are oblique in the same direction as those on the other side of the stator core.

摘要： A production method of a polyphase sequentially joined-segment coil of a rotary electric machine and a product produced by the same are provided. A production machine includes pairs of tines working to catch heads of conductor segments when they are twisted using rings. The tines are designed to be rotatable about an axis of the rings following rotation of the rings to absorb stress acting on insulating coating on the heads of the segments to minimize rubbing of the insulating coatings, thereby ensuring a desired degree of electrical insulation of the stator coil.

摘要： A stator includes a stator core and a stator coil formed of electric conductor segments. Each of the electric conductor segments has a pair of in-slot portions, a first end portion, and a pair of second end portions. The in-slot portions are respectively received in corresponding two slots of the stator core. The first end portion extends, on one axial side of the stator core, to connect the in-slot portions. The second end portions extend respectively from the in-slot portions on the other axial side of the stator core. Each of the second end portions includes an oblique part and a distal part. The oblique part extends obliquely with respect to an axial end face of the stator core. Corresponding pairs of the distal parts of the electric conductor segments are joined by welding. The oblique parts of the electric conductor segments have a higher hardness than the in-slot portions.

摘要： In a stator of a rotary electric machine that includes a stator winding and a stator core having a plurality of slots, the stator winding is constituted of a plurality of series-connected regular U-shaped segments each of which has a pair of in-slot portions and a plurality of U-shaped irregular segments each of which has a pair of in-slot portions disposed in a pair of slots that is suitable to connect the regular segments to form the stator winding and a continuous crossover portion crossing over some of the regular segments. The irregular U-shaped segments extend to be in contact with the turn portions of the regular segments. Therefore, the regular segments are connected by the irregular segments that have least electric resistance.

摘要： In manufacturing a stator coil for a rotary electric machine, a U-shaped segment is deformed at the turn portion thereof so that one of two straight portions thereof moves against the other one in a direction generally perpendicular to a borderline which connects two bordering points between the straight portions and the turn portion. The segment is twisted by moving the straight portions apart from each other. The segment is inserted into slots formed in a stator core so that the turn portion and end portions of the straight portions protrude from both axial end surfaces of the stator core. The end portions are folded in the circumferential direction of the stator core. The tips of the end portions are connected to tips of other segments.
