SUPERCONDUCTING REVOLVING DEVICE Russian patent published in 1997 - IPC

FIELD: power generation. SUBSTANCE: superconducting revolving device has rotor 1 of cryostat design built up of cold rotor 10 and superconducting winding 9 cooled down with coolant. Heat-shielding member 11 functions to isolate cold rotor 10 from heated components. Magnetic coupler functions to provide contactless joint with revolving shaft by means of magnetic forces. Stator spaced at desired distance from cold rotor 10 has armature winding. Rotor 10 incorporates cooler for cooling down the coolant circulating in it and heated while cooling down superconducting winding 9. EFFECT: improved reliability and cooling conditions. 10 cl, 15 dwg
