摘要： A method for manufacturing a coil includes: a winding step of forming a winding having expected slot placement portions and expected coil end placement portions; a protrusion forming step of forming the expected coil end placement portion into a protruding shape; a crank forming step of forming a stepped portion in the expected coil end placement portion; an opening step of forming the winding so that an interval between the pair of expected slot placement portions gradually increases in the stacking direction of the loops of the conductor; and an arc forming step of forming an edge of the expected coil end placement portion into an arc shape.

摘要： A stator assembling method for mounting a plurality of concentrically wound coils to an annular stator core, each of the concentrically wound coils being formed by winding a conductive wire for a plurality of turns, each of the concentrically wound coils having planned slot accommodation portions and planned coil end portions, the annular stator core having slots formed between adjacent teeth extending from a back yoke to a radially inner side, a spacing between the slots being widened toward a radially outer side. The stator assembling method includes the step of forming a coil assembly in which the plurality of the concentrically wound coils are disposed annularly and the step of pushing the coil assembly disposed in a space on an inner diameter side of the stator core to an outer diameter side and inserting the plurality of the concentrically wound coils into the slots of the stator core, in which each of the plurality of the concentrically wound coils has vertexes oriented outward in a axial direction in the planned coil end portions, and a distance in the axial direction between the vertexes of the planned coil end portions on both sides in the axial direction of each of the plurality of concentrically wound coils is gradually reduced toward the conductive wire mounted on the inner diameter side of the stator core from the conductive wire mounted on the outer diameter side of the stator core.
