    摘要： A system and method for cooling a superconductive rotor coil. The system comprises a rotatable shaft coupled to the superconductive rotor coil. The rotatable shaft may comprise an axial passageway extending through the rotatable shaft and a first passageway extending through a wall of the rotatable shaft to the axial passageway. The axial passageway and the first passageway are operable to convey a cryogenic fluid to the superconductive rotor coil through the wall of the rotatable shaft. A cryogenic transfer coupling may be provided to supply cryogenic fluid to the first passageway.

    摘要： An electrical component comprises a superconductive wire, the wire comprising a first wire segment joined to a second wire segment, wherein the first wire segment and the second wire segment differ in at least one property selected from the group consisting of magnetic field tolerance, temperature tolerance, ac loss, and strain tolerance, and wherein the magnetic field tolerance is measured by the relationship of critical current Ic to magnetic field H at a given temperature T below critical temperature Tc, the temperature tolerance is measured by the relationship of critical current Ic to temperature T at a given magnetic field below critical magnetic field Hc, the ac loss is measured by the amount of ac loss versus the frequency and magnitude of applied ac currents and fields, and the strain tolerance is measured by critical current Ic degradation with strain.

    摘要： A system for cooling a superconducting rotary machine includes a plurality of sealed siphon tubes disposed in balanced locations around a rotor adjacent to a superconducting coil. Each of the sealed siphon tubes includes a tubular body and a heat transfer medium disposed in the tubular body that undergoes a phase change during operation of the machine to extract heat from the superconducting coil. A siphon heat exchanger is thermally coupled to the siphon tubes for extracting heat from the siphon tubes during operation of the machine.
