    摘要: A method of manufacturing a stator coil to be wound in and around a stator by bending an insulating-coating conducting wire so as to alternately have slot-held conductor sections to be held in slots of the stator and a coil-end conductor sections each mutually connecting two of the slot-held conductor sections outside the slots. The method includes arranging three or more pairs of molds at predetermined intervals along the insulating-coating conducting wire, each pair of molds having paired molds facing each other with the wire located therebetween. First, the coil-end conductor sections are formed by moving the mold pairs such that the paired molds come closer to each other. Then the slot-held conductor sections are formed by moving the molds, in parallel, in both the longitudinal direction along which the insulating-coating conducting wire extends and in a direction perpendicular to the longitudinal direction.

    摘要: A coil forming method, a coil forming die assembly and a coil manufactured by the coil forming method are disclosed. The coil forming method comprises conducting preliminary forming work on a coil under a linear state before conducting bending work on the coil. The preliminary forming work including conducting compression work on the coil under the linear state to compress the coil in a region covering a rounded corner portion formed when bending work is conducted to decrease a dimension of the coil in a widthwise direction. The dimension of the coil is decreased in the widthwise direction by the nearly same dimension as that of the coil bulged in the widthwise direction when bending work is conducted in the absence of the preliminary forming work. This prevents the occurrence of bulging of the coil during bending work with an increase in lamination factor.

    摘要: The wire 30 forming the stator winding 20 includes the in-slot portions 40 to be disposed in the slots 14 and 15 of the stator core 12 and the turned portions 42 connecting the in-slot portions 40 disposed in the circumferentially different slots 14 and 15. The turned portions 42 formed on axial opposite end sides of the stator core 12. The crank portion 44 which does not twist is formed at substantially the center of the turned portion 42. Steps are formed at sections of the turned portion 42 which protrude outside the stator core 12 from the slots 14 and 15. Further, the turned portion 42 of the wire 30 also has two steps 48 formed between the substantially central crank portion 44 and each of the steps 46 formed at the protruding sections of the turned portion 42.
