ABSTRACT:
A superconducting bearing device includes a permanent magnet on a rotor, with a superconductor placed opposite the magnet. Flux trapped in the superconductor during cooling helps to stabilize the rotor. More specifically, the permanent magnet is mounted on the rotor so that, as the rotor rotates, its rotation does not alter the magnetic flux distribution around the axis of rotation of the rotor. The superconductor permits penetration of the magnetic flux from the magnet, being spaced from the magnet by a distance that permits a predetermined quantity of the magnetic flux to penetrate it, while not permitting rotation of the rotor to alter the distribution of the penetrating magnetic flux.
