摘要： An electrical machine includes a stator and a rotor. The stator has a central opening that is configured to receive the rotor. The rotor includes a generally cylindrical first section comprising a first material mounted on an axially extending shaft within the central opening. The rotor further includes a second section having a second material of a predetermined thickness that is plated integrally over at least a portion of the first section. The second material has a higher electrical conductivity relative to the first material. In certain embodiments, the electrical machine may include a stator support structure having a clamping member comprising a first material and configured to rigidly position the stator around the rotor.

摘要： The disclosed technology is a cryogenic static exciter. The cryogenic static exciter is connected to a synchronous electric machine that has a field winding. The synchronous electric machine is cooled via a refrigerator or cryogen like liquid nitrogen. The static exciter is in communication with the field winding and is operating at ambient temperature. The static exciter receives cooling from a refrigerator or cryogen source, which may also service the synchronous machine, to selected areas of the static exciter and the cooling selectively reduces the operating temperature of the selected areas of the static exciter.

摘要： A machine includes a rotatable rotor assembly having a number of salient poles. The machine further includes a stationary stator assembly having concentric inner and outer stators, at least one stationary superconducting field coil and at least one stator coil. The stationary superconducting field coil is disposed between the inner and outer stators and is mounted on at least one of the inner and outer stators. The stationary superconducting field coil and the salient poles are configured relative to each other, such that when the rotor assembly is rotated relative to the stator assembly around a predetermined axis, a rotating magnetic field is produced with an airgap flux direction substantially along the predetermined axis. The interaction between the stationary superconducting field coil and the rotating poles provides the only source of a time varying magnetic flux supplied to the stator coil.

摘要： A system and method for protecting a superconductor from a quench condition. A quench protection system is provided to protect the superconductor from damage due to a quench condition. The quench protection system comprises a voltage detector operable to detect voltage across the superconductor. The system also comprises a frequency filter coupled to the voltage detector. The frequency filter is operable to couple voltage signals to a control circuit that are representative of a rise in superconductor voltage caused by a quench condition and to block voltage signals that are not. The system is operable to detect whether a quench condition exists in the superconductor based on the voltage signal received via the frequency filter and to initiate a protective action in response.
