    摘要： Magnetic flux trapping clamps are provided that trap or pin the magnetic flux of ring shaped superconductive magnets in a high permeability metallic core located in the bore of the ring. Preferably, the superconductive magnets comprise a single crystal cut into a ring shape. Multiples of the flux-pinned magnets, having high magnetic strength, can be arranged in a variety of arrays for a range of applications. The devices offer several advantages over permanent or electromagnets. The devices easily activated by charging with a cryogenic fluid, to induce the superconductive effect, and deactivated by draining the fluid.

    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： Methods and systems provide pulsed-power to a load utilizing high temperature superconductors (HTS) within multiple pulsed-power devices. According to embodiments described herein, each pulsed-power device includes a HTS mounted on a rotor and an armature coil mounted on a stator. The rotor is positioned to allow a magnetic field within the HTS to induce a voltage in the armature coil when the rotor is rotating and to allow a magnetic field created by passing current through the armature coil to charge the HTS. Current created from the operation of a first pulsed-power device is routed to the armature coil in a second pulsed-power device to charge the associated HTS to a higher value. Subsequently, the second pulsed-power device is operated to produce current that is used to further charge the HTS in the first pulsed-power device. This bootstrapping procedure is repeated until all HTSs are fully charged.
