Patent ID: 8720042

Claim:
A method of manufacturing a stator, the method comprising the steps of: providing an insulated conductor coil, the insulated conductor coil produced by: providing an insulated conductor; forming an enamel layer on an outer periphery of the insulated conductor and forming an extruded resin coating layer on an outer periphery of the enamel layer; deforming the insulated conductor into a shape having straight in-slot conductor portions and coil end portions having bent portions to produce the insulated conductor coil; forming the extruded resin coating layer of the in-slot conductor portions in a crystalline resin state; forming the extruded resin coating layer of the coil end portions in an amorphous resin state, and forming the insulated conductor coil by deforming the insulated conductor to form the bent portions while the extruded resin coating layer of the insulated conductor is in the amorphous resin state and by deforming the coil end portions in the amorphous resin state, and mounting the insulated conductor coil to a core; heating the extruded resin coating layer of the insulated conductor coil to a temperature higher than or equal to a glass transition temperature to render the extruded resin coating layer into the crystalline resin state, and assembling the insulated conductor coil to the core.
