  • Systems and methods for activation of trapped field magnets
    Patent number: 9865383
    Abstract: A system for activating trapped field magnets in a superconducting material may include a superconducting material element and an electromagnet source disposed proximate the superconducting material element. The electromagnet source may be configured to produce a magnetic field pulse sufficient to activate the superconducting material element. The superconducting material element may be configured to retain a trapped magnetic field that is substantially equal to a magnetic field generated by the magnetic field pulse.
    Type: Grant
    Filed: January 21, 2015
    Date of Patent: January 9, 2018
    Assignee: NATIONAL OILWELL VARCO, L.P.
    Inventors: Drew Paul Parks, Roy Weinstein, Ravi-Persad Sawh, Keith Carpenter
  • Pulsed activation of trapped field magnets
    Patent number: 9847159
    Abstract: A system for activating trapped field magnets in a superconducting material is disclosed. The system includes a superconducting material element and an electromagnet source disposed proximate the superconducting material element. The electromagnet source is configured to produce a magnetic field pulse sufficient to activate the superconducting material element. Furthermore, substantially all of a magnetic field generated by the magnetic field pulse is contained within an area that has smaller physical lateral dimensions than the superconducting material element.
