THE METHOD OF MANUFACTURING AN INSULATED ELECTROMAGNETIC WINDING CAPABLE OF OPERATION AT TEMPERATURE ABOVE 300*C. WHICH COMPRISES APPLYING TO A CONDUCTOR A FLEXIBLE ABRASION-RESISTANT INSULATION COMPRISING A COVERING OF INORGANIC DIELECTRIC MATERIAL BONDED IN PLACE BY AN ORGANIC VARNISH, FORMING THE THUS-INSULATED CONDUCTOR INTO A WINDING, HEATING THE WINDING TO A TEMPERATURE ABOVE THE PYROLYSIS POINT OF THE ORGANIC VARNISH FOR A SUFFICIENT PERIOD OF TIME TO PYROLYTICALLY VOLATILIZE ALL ORGANIC MATTER FROM THE COVERING AND LEAVE THE FORMED WINDING INSULATED SOLEY BY THE INORGANIC DIELECTRIC MATERIAL.
