摘要： The continuous wires respectively have U-shaped parts and straight parts. The method includes: a transposition shape forming step of forming transposition shapes in each of which, among at least the two continuous wires belonging to an identical phase, the U-shaped part of one of the continuous wires is disposed inside the U-shaped part of the other one of the continuous wires; an inclined part forming step of causing the pairs of straight parts of the continuous wires respectively formed with the transposition shapes to be offset to form inclined parts on the continuous wires; and a folding step of folding the continuous wires formed with the inclined parts to form the turning parts and the slot disposition parts. The inclined part forming step and the folding step are alternately performed.

摘要： A coil for a rotary electric machine is mounted in a plurality of slots of a stator core having the slots in a circumferential direction. An overlapping coil-type wave winding coil constituted by a coil wire having a plurality of slot accommodating portions accommodated in the slots and a plurality of coil end portions interconnecting, in a chevron shape, the slot accommodating portions next to each other outside the slots in an axial direction of the stator core constitutes the coil. At least two layers of the coil wire are connected by a continuous wire-based connecting portion, folded back in the connecting portion, and stacked.

摘要： A coil-forming apparatus for forming a bare coil wire into a U-shape, the apparatus including: one bare coil-wire holding unit that winds and holds a bare coil wire; a take-up drum that includes one or a plurality of housing units that house the bare coil wire supplied from the one bare coil wire holding unit at a circumference; a cutting member that cuts the bare coil wire housed in housing units and wound around the take-up drum, at a portion of the circumference of the take-up drum; a drawing member for drawing the bare coil wire outward in a radial direction of the take-up drum after being cut by the cutting member, from a position separated from the cutting member; and a forming unit that forms the bare coil wire drawn by the drawing member into a U-shape.

摘要： A conductive wire piece set forming method includes: a bending step of bending a conductive wire piece set in a second bent portion; a restraining step of restraining the second bent portion of the conductive wire piece set and a portion adjacent thereto with a clamp portion; and a twisting step of twisting the conductive wire piece set by rotating the clamp portion. The restraint of the conductive wire piece set is performed in such a way that the conductive wire pieces form a predetermined angle with each other.
