Abstract
A manufacturing method for a stator winding coil includes: a bulging portion forming step that forms a bulging portion on a conductor wire; a crank portion forming step that forms a crank portion on the central portion of the bulging portion; an oblique portion forming step that forms oblique portions on the conductor wire at two ends of the bulging portion; a rectilinear portion forming step that forms rectilinear portions on the conductor wire at opposite ends of the oblique portions from the bulging portion; and a circular arc forming step that forms the oblique portions into a circular arc shape after forming the rectilinear portions.
