Abstract: A stator includes a multi-phase stator coil comprised of phase windings. Each of the phase windings is formed of a continuous electric conductor and includes in-slot portions and coil end portions. Each of the in-slot portions is received in one of slots of a stator core. Each of the coil end portions is located outside the slots so as to connect one adjacent pair of the in-slot portions. Each of the coil end portions includes at least one oblique part that extends obliquely at an oblique angle with respect to either an axial direction or a circumferential direction of the stator core. The oblique angles of the oblique parts of the coil end portions in at least one of the phase windings of the stator coil are set to be different from the oblique angles of the oblique parts of the coil end portions in the other phase windings.

Abstract: A circular wire with a circular cross section is wound on a coil reel. When a winding-form motor rotates a winding form, the circular wire is pulled and drawn from the coil reel. Rectangular forming rollers press the circular wire, so that a rectangular wire with a rectangular cross section is formed. The rectangular wire is directly wound on the winding form to be formed into a rectangular-wire coil. Because forming rectangular wire and winding on the winding form are carried out in a sequence of contiguous processes, a separate process for removing torsion set of the rectangular wire is unnecessary. The rectangular-wire coil can be formed from inexpensive circular material wire by a simple and low-cost apparatus. It is also possible and preferable to make dimensions and a shape of the rectangular wire variable by controlling clearance widths between the forming rollers and tension acting on the rectangular wire that has passed through the rollers.
