Superconducting equipment such as current collector rings and homopolar motors / generators

摘要

The equipment (ie current collector ring or homopolar motor / generator) (40, 50, 80) is adapted to provide an electrical contact between the stator and the rotor (41, 83) and is fixed A current carrying brush spring (31, 84) mounted on a child and having two opposing surfaces, and a fibrous brush assembly (35, 69) mounted on a conductor, the brush assembly being the tip of the fiber A brush assembly having a bundle of fibers (36, 71) arranged to engage the rotor to transfer current between the stator and the rotor, and a current carrying brush spring A ribbon of superconducting material (33, 85) mounted on each opposing surface and in communication with the stator and brush assembly; and another ribbon (29, 86) of superconducting material mounted on the rotor. ,including. The equipment is immersed in a cryogenic fluid at a temperature below the transition temperature of the superconducting material, which will reduce the electrical resistivity of the equipment and increase the current transfer performance of the equipment. become.
