Windings for electrical machines and appliances, which windings remain mechanically stable even when the operational temperature is exceeded for a short period and ensure good heat transfer between the winding and the iron of the magnet core without additional impregnation, are produced by lining the slots in the magnet core with a slot liner coated on at least the side facing the magnet core with at least one B-state resin which is completely non-tacky at room temperature but is capable of being cured and becomes tacky at the temperatures employed in the curing of the thermosetting adhesive layer of the adhesive varnished wire used, by making the winding from adhesive varnished wire with a thermosetting adhesive layer and curing by heating the coating on the slot liner and the adhesive layer on the adhesive varnished wire.
A method of forming windings on magnetizable cores for small electrical machines, wherein said cores have a plurality of openings for receiving said windings, said method comprising the steps in sequence of:
A wound core for a small electrical machine and comprising in combination:
