摘要： A flywheel system suitable for storing energy when demand for energy from a power plant is low, and from which energy can be retrieved when energy demand increases. The flywheel includes (a) a circular composite or metallic glass ring with a radial width limited to less than about 30 percent of the ring's outer radius, and (b) at least one spoke extending along a diameter of the ring, and attached to the ring at either end. The spoke has sufficient radial extendability due to either bending and elastic radial elongation, or only elastic elongation so that, when the flywheel rotates at operating speed, the spoke extends radially to match the radial growth of the ring, without subjecting the flywheel to significant tension at points of attachment of the spoke to the ring. In one embodiment, both flywheel ring and spoke are made of oriented high strength fibers embedded in a thermoplastic resin. Also provided are a magnetic bearing and motor/generator system that are of an axial-gap design so that magnets are held in a substantially fixed position relative to each other, as the flywheel expands radially under centrifugal forces. Further, both motor/generator and flywheel bearings utilize a system of permanent magnets alternating with a high magnetic permeability composition in order to produce highly uniform magnetic fields in the bearing to reduce magnetic drag and improve efficiency, and to produce high torque in the motor generator. The flywheel bearing assembly includes a bulk high temperature superconductive magnet that provides lateral stability to the flywheel.

摘要： Gravitational acceleration is measured in all spatial dimensions with improved sensitivity by utilizing a high temperature superconducting (HTS) gravimeter. The HTS gravimeter is comprised of a permanent magnet suspended in a spaced relationship from a high temperature superconductor, and a cantilever having a mass at its free end is connected to the permanent magnet at its fixed end. The permanent magnet and superconductor combine to form a bearing platform with extremely low frictional losses, and the rotational displacement of the mass is measured to determine gravitational acceleration. Employing a high temperature superconductor component has the significant advantage of having an operating temperature at or below 77K, whereby cooling may be accomplished with liquid nitrogen.

摘要： A superconducting bearing device comprising a superconductor mounted on a stationary member and a magnet section to be mounted on a rotating member, the superconductor and the magnet section being disposed to oppose each other with a gap therebetween. Also disclosed is a method for producing the magnet section thereof, wherein the magnet section consists of a plurality of annular permanent magnets which are concentric with the axis of the rotating member and also include at least one soft magnetic yoke disposed between these annular permanent magnets. Each annular magnet, in turn, may be comprised of a plurality of arcuate magnet portions whose joint surfaces may be concentrically or axially staggered to disperse nonuniform flux densities observed at their junction surfaces. The joint surfaces between the annular and magnets and the interposing rings may be curved or slanted to reduce axial displacement when the magnet section is rotated. Also, the yoke members may protrude towards the superconductor relative to the permanent magnets comprising the magnet section, and these yokes may be optimally shaped to concentrate and direct magnetic flux to the opposing superconductor in conjunction with curled magnetization of the permanent magnets. Finally, one or more restraining members or wedge portions may be fitted to the magnet section to radially and circumferentially compress the permanent magnets sections and prevent their displacement and breakage at high rotational speeds.

摘要： A superconducting bearing device comprises an annular permanent magnetic portion 2 disposed concentrically with a rotary body 1 in the form of a vertical shaft, and superconductors 8 opposed to the lower end face of the magnet portion 2 and vertically spaced apart therefrom. The permanent magnet portion 2 comprises a disk 4 fixedly mounted on the rotary body 1, and annular permanent magnets 6a, 6b arranged on the disk 4 at a spacing radially of the rotary body 1. Each of the magnets 6a, 6b has upper and lower ends magnetized to polarities opposite to each other, and the adjacent magnets 6a, 6b are magnetized to polarities opposite to each other at the upper ends, as well as at the lower ends. The radial spacing between the magnets 6a, 6b is optimized in accordance with the radial dimension (width) of the magnets 6a, 6b. This improves the device in load capacity and rigidity and prevents the deflection of axis of the rotary body 1, enabling the bearing device to support the rotary body 1 in a noncontact state with good stability.

摘要： A superconducting bearing device comprises a permanent magnet portion fixedly mounted on a rotary body concentrically therewith, and a superconductor opposed to the magnet portion and spaced apart therefrom radially of the rotary body, the magnet portion being so disposed that the rotation of the rotary body does not alter the magnetic flux distribution around the axis of rotation of the rotary body, the superconductor being disposed at a position which is spaced apart from the magnet portion by a distance permitting a predetermined quantity of magnetic flux thereof to penetrate into the superconductor and which does not permit the rotation of the rotary body to alter the penetrating magnetic flux distribution. The magnet portion comprises a plurality of annular permanent magnets arranged at a spacing along the axis of rotation of the rotary body and an annular yoke of ferromagnetic material interposed between each two adjacent magnets. Each of the magnets is magnetized to opposite polarities at its respective opposite ends in the direction of the axis of rotation, each two adjacent magnets being magnetized to the same polarity at their ends opposed to each other with the yoke interposed therebetween.
