A super-conductive, cryogenically-cooled electrical machine comprises a superconductive exciting winding located in a hollow rotor and a system for cooling the ends of the rotor shaft. The cooling agent is delivered from one end of said shaft to the rotor space through the axial passage of the shaft whose ends are made of at least two coaxial tubes secured together by threading. The cooling agent is removed through the clearances of said thread and such construction of the rotor shaft reduces heat influxes to the superconductive exciting winding at least threefold and lowers the weight-to-power ratio of the machine at least fivefold.
