Abstract
A stator coil forming method includes a bending step of bending portions of a linear lead wire so as to form bent portions; a cutting step of cutting curve parts of the bent portions thus formed, along a perpendicular plane that is approximately perpendicular to an extending direction of the lead wire so as to form coil segments; a U-shape forming step of bending the coil segments in a U-shape; an assembling step of assembling the coil segments to respective slots of a stator core; a tilting step of tilting both distal ends of the coil segments in a circumferential direction of the stator core so that cut surfaces of the distal ends are oriented toward a central-axis direction of the stator core; and a joining step of joining the distal ends of the coil segments adjacent to each other in a radial direction of the stator core.
