  • Satellite angular momentum control system using magnet-superconductor flywheels
    Patent number: 6231011
    Abstract: A torque/reactive momentum wheel control system for use in satellites for dynamic attitude maintenance and alteration where the flywheel of each momentum wheel is levitated by a high-temperature superconducting element repulsively interacting with permanent magnets in the flywheel. The spin rate (rpm) of the flywheel being controlled by either an active magneto or electromagneto drive system. Each momentum wheel is cooled by a cryo-cooler and can have a total weight of about 10 Kg to a fraction of 1 Kg and delivering 3.5 Js with less than 1 W loss.

  • Magnet-superconductor flywheel and levitation systems
    Patent number: 5831362
    Abstract: Disclosed is a flywheel system for storing kinetic energy which utilizes a high temperature superconductor/magnet system for the flywheel bearings. The flywheel includes a first magnet, and having a ring magnet defining an opening. The levitation system includes a magnet for attractively interacting with first flywheel magnet, with a high temperature superconductor interposed between them, and further includes a magnet system for repulsively interacting with and partially inserted into the ring magnet.

  • Vibration-free levitated platform
    Patent number: 5726512
    Abstract: An isolation system for isolating a first object from vibrations from a second object. Such vibrations will have three orthogonal components, one oriented along a line between the objects, and two oriented 90.degree. apart in a plane normal to that line. The system includes three superconductor/magnet stages, each stage designed to extinguish one of the orthogonal components.
