Cooling system for rotors of electric machines, especially for turbo-generator rotors with a superconductive field winding

摘要: Cooling system for a rotor of an electric machine having superconductive field winding and formed drum with at least one outer, substantially hollow cylindrical body co-rotating cold shield, inner fastened given locations within the outer so as to be thermally insulated serving coil-winding support, fastening being cooled, mixing chamber located periphery containing phase mixture coolant fed thereto from outside, forming, during rotation rotor, radially outwardly flung liquidring vapor column coaxial thereto, including channels conducting first flow liquid cooling second partly vaporized returning flow, after it has traversed winding, back discharging out machine.
