  • Axial flux electric machine
    Patent number: 9391500
    Abstract: An electric machine is described. The electric machine includes a rotor comprising a rotor disk and a plurality of permanent magnets magnetically coupled to the rotor disk. The plurality of permanent magnets include a substantially flat profile and are aligned in a substantially planar array. The electric machine also includes a stator comprising a solid stator core and a plurality of coils each wound around a coil insulating member. The stator core includes a plurality of stator teeth extending substantially parallel to an axis of rotation of the rotor.
    Type: Grant
    Filed: March 22, 2011
    Date of Patent: July 12, 2016
    Assignee: Regal Beloit America, Inc.
    Inventors: Michael D. Smith, William A. Ziegler, Michael Garrett, Dean James Patterson, Roger C. Becerra, Ludovic Chretien, Darrel Buttram, Steven Peter Camilleri

  • Systems and methods for shielding an electric machine
    Patent number: 7952251
    Abstract: A method for reducing leakage currents in an electric machine is described. The method includes positioning a plurality of leakage current shields between windings and teeth of a stator, and coupling at least one of the plurality of leakage current shields to a reference point, wherein an electric potential at the reference point is not earth ground.
