Superconducting electrical machine with rotor and stator having separate cryostats
Patent
·
OSTI ID:1479676
A superconducting electrical machine includes a rotor and a stator. The rotor includes rotor windings configured to superconduct when cooled in a rotor cryostat to a temperature no greater than a rotor superconducting temperature. The stator includes a stator windings configured to superconduct when cooled in a stator cryostat to a temperature no greater than a stator superconducting temperature. The rotor cryostat surrounds the rotor and is configured to allow transport of a first coolant through a plurality of conduits adjacent to the rotor windings in order to draw heat from the rotor windings and reduce the temperature of the rotor windings to a temperature no greater than the rotor superconducting temperature. The stator cryostat surrounds the stator and is configured to allow transport of a second coolant through a plurality of conduits adjacent to the stator windings in order to draw heat from the stator windings and reduce the temperature of the stator windings to a temperature no greater than the stator superconducting temperature.
