Publication number: 20070278879Abstract: A stator for an electrical machine includes teeth assembled from a plurality of stacked laminations mounted on a cylindrical protective surface thereby forming a plurality of slots. The stator also includes an armature winding assembled within the teeth by inserting components of the armature winding into the plurality of stator slots from positions external to the teeth in a manner that facilitates mitigating potential for coil distortion. The armature winding includes a plurality of coils that each include an end winding. The stator further includes a segmented yoke inserted around the armature winding in a manner that facilitates mitigating a potential for disturbing the end winding of the coils. Independently assembling the stator components in this manner facilitates varying a thickness and/or the number of heat conducting laminations between the yoke and teeth that subsequently facilitates heat transfer from the armature winding to an outer pressure casing of the machine.Type: ApplicationFiled: June 2, 2006Publication date: December 6, 2007Inventors: Christopher Anthony Kaminski, Blake Weldon Wilson, James Michael Fogarty, Emil Donald Jarczynski, John Russell Yagielski, Konrad Roman Weeber

Patent number: 6704993Abstract: A polyphase electric generator (10) is disclosed having a fixed output voltage configurable to virtually any voltage level within a certain range of voltages. The armature winding (18) of the generator is arranged in a combined Delta and Wye topology (60, 66). Each phase winding (20, 54) in the armature is partitioned into first and second sections of the phase winding (56, 58). The first sections (56, 62, 64) of each of the phase windings are arranged together in a Delta topology (60). Each of the second sections of each phase winding is arranged in a Wye topology (66) with a pair of the first winding sections. Each of the second sections (58) are connected at one end to a node (68) of the Delta topology where two of the first winding sections are connected. The opposite ends (70) of the second sections of each phase winding are connected to output terminals (26) of the armature to provide a line-to-line voltage output.Type: GrantFiled: January 4, 2002Date of Patent: March 16, 2004Assignee: General Electric CompanyInventor: James Michael Fogarty

Patent number: 6683398Abstract: 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: GrantFiled: December 1, 2000Date of Patent: January 27, 2004Assignee: General Electric CompanyInventors: Wei Tong, Frederick John Rink, Jr., James Michael Fogarty, John Wesley Griffith, Christian Lee Vandervort
