Abstract
A device {i.e., a slip-ring or a homopolar motor/generator) () is adapted to provide electrical contact between a stator and a rotor (), and includes: a current-carrying brush-spring () mounted on the stator, and having two opposite surfaces; a fibrous brush assembly () mounted on the conductor, the brush assembly having a bundle of fibers () arranged such that the tips of the fibers will engage the rotor for transferring electrical current between the stator and rotor; a ribbon () of superconducting material mounted on each opposite surface of the current-carrying brush-spring and communicating with the stator and the brush assembly; and another ribbon () of superconducting material mounted on the rotor. The device is submerged in a cryogenic fluid at a temperature below the transition temperatures of the superconducting materials such that the electrical resistivity of the device will be reduced and the current-transfer capability of the device will be increased.
