ABSTRACT:
A non-contacting superconducting rotating assembly is described which includes a floating, unsupported and stable rotor. The assembly includes first and second bearings comprised of a material which exhibits Type II superconducting properties. The rotor includes a magnetic pole at each of its extremities, each pole resting in a bearing. The polar axis of each pole is colinear with the rotating axis of the rotor. A temperature bath is provided for maintaining the bearings at or below their critical superconducting temperature and a motive mechanism provides for rotation of the rotor. Each magnet pole is thereby levitated and adapted to rotate in a stable, non-contacting position by the field and pinning effects generated by the associated bearing.
