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.
