Abstract
Individual cables are provided with lateral ridges to be snapped behind noses of cutouts in rails by means of which the winding is assembled and retained. The rope-ladder-like assembly is installed by placing the cable portions, resembling the rungs, into grooves of the stator core, also having noses behind which the cable ridges are lodged.
