SUPERCONDUCTING MAGNETIC BEARING

Title:

SUPERCONDUCTING MAGNETIC BEARING

Document Type and Number:

WIPO Patent Application WO/2004/013504

Kind Code:

A1

Abstract:

A superconducting magnetic bearing (22) comprises a stationary side bearing part (23) having a ring superconductor unit (26) provided to a stationary part (20) and a rotary side bearing part (24) having a ring permanent magnet unit (28, 29) so provided to a rotator (21) as to be opposed to the superconductor unit (26). The rotator (21) is supported with the stationary part (20) with no contact by the pinning effect of the superconductor constituting the superconductor unit (26). The permanent magnet unit (28, 29) is composed of permanent magnet single pieces stacked with insulating layers therebetween.
