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.
