摘要： A superconduction bearing is provided in which the load capacity and rigidity of a rotary member are improved, run-out of the rotary member is prevented to support the rotary member in a stable, non-contacting manner, and manufacturing cost is reduced. The superconduction bearing includes a rotary member and a disk formed on the rotary member. The disk has permanent magnets provided thereon. The permanent magnets are magnetized to have opposite poles on top and bottom sides thereof. A permanent magnet section is thus formed by the disk and the permanent magnets. Superconductors are concentrically provided for rotatably supporting the rotary member. The permanent magnet section and the superconductor section are positioned opposite to each other. The width and thickness of the permanent magnets are set to 5 to 10 times the distance between the permanent magnet section and the superconductor section.

摘要： A rotary member is continually held suspended by a strong pinning force of oxide superconductors in a superconductive state. The magnetic field of magnets on the suspended rotary member is distributed concentrically about the center of the pinning force, so that the rotary member can be continually rotated in a non-contacting state while being lifted off the high temperature oxide superconductors. The rotary member is rotated in a high vacuum and is held to continually rotate for an extended period of time. Kinetic energy is stored in and recovered from the rotating member via an input/output device.

摘要： A laminated structure for a superconducting bearing includes at least two magnets stacked in opposing polarity with at least one metallic shim being disposed between adjacent magnets. The multiplicity of opposing polarity magnets causes an increase in flux density gradient and, therefore, bearing stiffness. The laminated structure for a superconducting journal bearing has annular permanent magnets that are magnetized and stacked axially. This structure is disposed within a hollow cylinder made of superconducting material. When the cylinder is made of a Type II superconducting material, the superconducting journal bearing provides support in both the radial and axial directions.

摘要： A magnetic bearing having a rotatable member and a stationary member on one of which is mounted a superconductor while on the other is mounted a set of permanent magnets or electromagnets arranged as a quadrupole or multiple dipoles. The magnetic member, which is in the form of a dipole, a quadrupole, or other multiple dipole, such as an octopole, is positioned to enable the magnetic fields generated by the permanent magnets to interact with the superconducting material and to confine the shaft in all directions in the desired location. The bearing systems can be used as either a thrust bearing or as a journal bearing, or as both. Each dipole may be twinned to reduce magnetic field asymmetry and reduce energy dissipation upon rotation. The superconductor may be laminated, and/or additional magnets may be located outside the superconductor in order to increase the bearing stiffness and rigidity.

摘要： A superconducting motor including a rotor, a heat sink, and a bearing. The rotor includes a superconducting winding formed from a superconducting material. The heat sink is positioned within the superconducting motor to absorb heat produced by the superconducting motor. The bearing includes an inner race, an outer race, and a rolling element. The bearing rotatably supports the rotor and is thermally connected to each of the rotor and the heat sink to transfer heat from the rotor to the heat sink. The rolling element is formed from a material having, at 25 K, a thermal conductivity of 20 W/mK or more and an ultimate tensile strength of 650 MPa or more. The rolling element may be formed from a copper alloy.
