摘要： A superconductor magnetic bearing includes a shaft (10) that is subject to a load (L) and rotatable around an axis of rotation, a magnet (12) mounted to the shaft, and a stator (14) in proximity to the shaft. The stator (14) has a superconductor thin film assembly (16) positioned to interact with the magnet (12) to produce a levitation force on the shaft (10) that supports the load (L). The thin film assembly (16) includes at least two superconductor thin films (18) and at least one substrate (20). Each thin film (18) is positioned on a substrate (20) and all the thin films are positioned such that an applied magnetic field from the magnet (12) passes through all the thin films. A similar bearing in which the thin film assembly (16) is mounted on the shaft (10) and the magnet (12) is part of the stator (14) also can be constructed.

摘要： A superconducting bearing device for supporting a rotary shaft (rotary body) 2 in a noncontact state for rotation at a high speed. A superconducting bearing 4 for supporting the rotary shaft 2 in a noncontact state relative to a housing 1 comprises permanent magnets 14 mounted on the rotary shaft 2, and Type II superconductors 17 attached to the housing 1 and opposed to the magnets as vertically spaced apart therefrom. A mechanical catcher bearing 21 comprising a thrust ball bearing is disposed between the housing 1 and the rotary shaft 2 at opposed portions thereof. An initial position determining mechanism is provided for lifting a bearing ring 23 of the catcher bearing 21 on the housing 1 to position the housing 1 and the rotary shaft 2 in place relative to each other, whereby the superconductors 17 and the permanent magnets 14 on the shaft 2 can be positioned in place relative to each other. The superconducting bearing 4 can be operated efficiently by suitably determining the relative position. The catcher bearing 21 prevents damage to the rotary shaft 2 and parts therearound when the superconductors 17 of the bearing 4 become normally conductive.

摘要： 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.

摘要： A passive superconductor bearing system and process for supporting a rotating member uses permanent magnets in the bore of the rotating member, stationary permanent magnets which encircle the shaft, superconducting materials at the shaft ends, and a duct and pinhole outlet which directs a flow of gas towards one shaft end. The stationary permanent magnets interact with the permanent magnets in the shaft to radially position the shaft in the center of the stationary permanent magnets due to radial repulsive forces between poles of the same polarity. In order to enhance stability, a gas jet is directed towards one end of the shaft to counteract the unbalancing axial force on the shaft caused by permanent magnet interaction. The superconductor-magnet interaction generates a restoring force as the shaft is transversely displaced in any direction away from its equilibrium position. The interaction does not assist shaft rotation, but adds to the stiffness and damping of the bearing system.

摘要： A flywheel having superconductor bearings has a lower drag to lift ratio that translates to an improvement of a factor of ten in the rotational decay rate. The lower drag results from the lower dissipation of melt-processed YBCO, improved uniformity of the permanent magnet portion of the bearings, operation in a different range of vacuum pressure from that taught by the art, and greater separation distance from the rotating members of conductive materials.

摘要： 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.

摘要： A device is provided for suspending an external load by means of a magnetic field and a superconductor. The superconductor is supported in a magnetic field which penetrates the superconductor. A magnet is suspended below the superconductor and oriented so that its magnetic moment is aligned parallel to the magnetic field. The magnet is provided with a coupling means so that it can be coupled to an external load. Either a vertical or a horizontal magnetic field can be used. In one embodiment, the load-carrying member is a composite material suspended from a supported magnet. The composite consists of a superconducting phase and an attractive phase comprising either a magnet, a ferromagnetic material, or a paramagnetic material. In another embodiment, a device for concentrating flux is provided by placing a superconductor between the source of the magnetic field and the position in which the concentrated flux is desired.
