摘要： 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.

摘要： An electrical machine with cryogenic cooling has a hollow rotor filled with a coolant and comprising a superconducting winding provided with at least two supply leads being cooled. One of the supply leads is connected to a plus sign current-collecting means and is disposed in at least one cooling duct for cooling one end part of the hollow shaft of the rotor. The cooling ducts for cooling both end parts of the hollow shaft of the rotor are connected, via respective exhausting means for withdrawing the coolant from the rotor, with respective coolant collecting chambers. The other supply lead is coupled to a minus sign current-collecting means. The hollow shaft of the rotor is provided with a passage for feeding the coolant to the superconducting winding, said passage being connected with an inlet means for introducing the coolant to the rotor, the inlet means being disposed in one end part of the hollow shaft of the rotor. There is a passage in the other end part of the shaft, which communicates with the rotor cavity and with a respective coolant collecting chamber via a respective exhausting means for withdrawing the coolant from the rotor. The supply lead connected to the minus sign current-collecting means is disposed in this passage and each of said current-collecting means is disposed in a respective coolant collecting chamber.

摘要： A super-conductive cryogen-cooled electrical machine comprises a rotor disposed within a hollow stator with an annular gap which is evacuated and kept under vacuum by means of at least two shells furnished with ports and position concentrically with a clearance or gap therebetween. One of said shells is supported in a cantilevered fashion by the rotor on the end face thereof to be coaxial therewith and the other being supported in a cantilevered fashion by the stator on the end face thereof opposite said end face of the rotor. The ports in the rotor-supported shells are made so that their axes form an acute angle .alpha. with tangent lines drawn to the shell periphery from the points where the port axes intersect the shell envelope in the direction of the rotor rotation, while the ports in the stator supported shells are made so as to form, in a similar way, an angle .beta.=180.degree.-.alpha.. The proposed construction of the electrical machine permits increasing the reliability and efficiency of the vacuum heat insulation of the rotor and reducing manufacture and operating costs.
