ABSTRACT:
A method of producing a coil which comprises steps of bending each of straight coil wires into a rectangular wave shape including in-slot portions to be disposed in slots of a stator core and turned portions connecting between the in-slot portions, turning a coil bend-forming portion that is one of the in-slot portions of each coil wire which becomes a folded bend of a phase winding by 180° around an axis thereof, twisting the turned portions of the coil wires together to weave the coil wires into a wire bundle, and folding the wire bundle at the coil bend-forming portions of the coil wires to place sides of the wire bundle to overlap each other to make the coil, thereby eliminating the 180° twisting of the coil bend-forming portions to produce the coil without any undesirable deformation of the phase windings.
