Abstract: The method of manufacturing a coil assembly for a stator formed with slots includes a coil wire combination forming step of forming a band-like coil wire combination by overlapping a plurality of coil wires while forming them with in-slot portions to be accommodated in the slots and turn portions each connecting each adjacent two of the in-slot portions, and a shaping step of shaping the band-like coil wire combination into a cylindrical shape by helically winding the band-like coil wire combination. The coil wire combination forming step is carried out by performing an interlaced part forming step of forming an interlaced part by overlapping the coil wires with each adjacent two of the coil wires intersecting with each other and a non-interlace part forming step of forming an interlaced part by overlapping the coil wires with each adjacent two of the coil wires not intersecting with each other.

Abstract: In manufacturing a stator coil for rotary electric machine having phase windings, plural conductive shaped wire members are integrated mutually to form an integrated body. Each shaped wire member has plural straight portions and plural turn portions alternately connecting adjacent straight portions at each of both ends of each straight portion. The body has plural straight superposed portions each formed by mutually superposing the plural straight portions. A wound-up body has plural straight stack portions The straight portions are fitted to respective fitting grooves of an alignment member, the fitting grooves being formed in the alignment member at intervals each corresponding to the size of a gap between adjacent straight stack portions. The integrated body is wound about a core member together with the alignment member, with the straight portions being fitted to the alignment member to form the wound-up body.

Abstract: A rotor provided in rotary electric machines comprises a stator core having a radial direction and slots provided with bottomed openings directed in the radial direction. The rotor also comprises a stator coil comprising slot accommodation portions being accommodated in the slots of the stator core and coil end portions each connecting mutually adjacent slot accommodation portions among the slot accommodation portions and respectively protruding from both end faces of the stator core. The stator coil is pre-formed into a cylindrical shape before the slot accommodation portions are accommodated into the slots of the stator core. The slot accommodation portions are formed to respectively have convex parts each protruding toward an opposite way to the slot openings, before the slot accommodation portions are accommodated into the slots. The convex parts are pressed by the stator core toward the openings during accommodation of the slot accommodation portions into the slots.
