Abstract

947,652. Insulating, cooling and securing end windings in dynamo electric machines. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. March 7, 1961, No. 8282/61. Heading H2A. The stator end windings of a dynamoelectric machine are cooled by embedding one or more cooling tubes of electrically-insulating material in the cast insulating material, e.g. ethoxylin resin, used to support and insulate the windings. A high heat-conductivity filler, e.g. quartz sand, may be added to the insulating material and a liquid or gaseous cooling fluid used. Castable silicone asbestos or silicone rubber could be used for the insulating material.
