STATOR MANUFACTURING METHOD AND STATOR

WIPO Patent Application WO/2011/161776

A1

A stator manufacturing method which manufactures an insulated conductor coil (100) and mounts the insulated conductor coil (100) to the core, the insulated conductor coil (100) being formed by deforming an insulated conductor (11) into a shape having rectilinear in-slot conductor sections (11B) and coil end sections (11A) having bent sections, the insulated conductor (11) having an enamel layer formed on the outer periphery thereof and also having an extruded resin coating layer formed on the outer periphery of the enamel layer. The method comprises: a first step in which, while the extruded resin coating layer of the insulated conductor (11) is in a non-crystalline resin state, the insulated conductor (11) is deformed to form the bent sections, thereby forming the insulated conductor coil (100); a second step in which the extruded resin coating layer of the insulated conductor coil (100) is changed into a crystalline resin state by heating the extruded resin coating layer to a temperature higher than or equal to the glass transition temperature; and a third step in which the insulated conductor coil (100) is mounted to the core.
