ABSTRACT:
A method of making a laminated stator assembly for a dynamoelectric machine which comprises machining an inner stator member as a single detail having a plurality of winding retaining grooves and plurality of radial slots all of which terminate at or near a central core portion of the stator member. The material between the radial slots form spaced apart radially tapered sections which terminate in the central core portion and the stator member can serve as its own winding mandrel for winding coils in place in the grooves. After such winding an outer shell of magnetic material is fitted over the inner stator member. The coils, spaces between the radially tapered sections, and surfaces of the groove are provided with suitable, electrically insulating bonding material which after curing bonds such elements into a single unit. The central core portion is then machined away so that there is longer a direct connection between the interior ends of the tapered sections and the stator member.
