  • Generator magnetic armature wedge
    Patent number: 6683398
    Abstract: A magnetic armature wedge is provided for replacing conventional dovetail wedges in high-powered large-size turbine generators. The magnetic armature wedges that are used for supporting the armature bars are made by molding resin, e.g., epoxy with ferromagnetic particles, wires, laminates and the like embedded therewithin. The magnetic particles, wires, laminates and the like increase the magnetic permeability of the wedges causing higher slot flux leakage and high generator subtransient reactants.
    Type: Grant
    Filed: December 1, 2000
    Date of Patent: January 27, 2004
    Assignee: General Electric Company
    Inventors: Wei Tong, Frederick John Rink, Jr., James Michael Fogarty, John Wesley Griffith, Christian Lee Vandervort

  • Turbine rotor sub-slot scoops
    Patent number: 6483211
    Abstract: A rotor assembly for a turbine comprising a plurality of radially oriented, axially extending slots, each slot having a plurality of field windings seated therein; a sub-slot cover separating the windings from a base of the slot, thereby forming a coolant sub-slot radially inwardly of the windings; and an aerodynamic scoop fixed at an entrance to the sub-slot.

  • Generator armature bar support system and related method
    Patent number: 6369482
    Abstract: A generator armature bar support system includes in a temporary assembly state, an elongated armature bar having a bottom surface, a top surface and a pair of side walls. A spacer is then temporarily located on the top surface of the armature bar; and an elastomer stretched and wound about the armature bar and spacer along substantially the length of the armature bar.

  • Direct-cooled dynamoelectric machine stator core with enhanced heat transfer capability
    Patent number: 5869912
    Abstract: In a dynamoelectric machine stator core assembly wherein adjacent packages of stacked laminations are separated by a plurality of radially extending spacer blocks, and wherein each adjacent pair of spacer blocks define in cooperation with adjacent axially spaced laminations, a cooling duct, the improvement comprising a plurality of turbulator elements in each cooling duct, each turbulator element extending into the duct from one of the adjacent axially spaced laminations.
