Patent number: 8220138Abstract: The present invention provides an apparatus for the horizontal stacking of laminations 10 and donuts to form a stator core. A stator generator frame 2 has multiple keybars 6 that run the axial length of the frame. The laminations 10 have grooves 12 there-in that engage the keybars to provide a secure fit of the laminations to the generator frame. By extending two or more of the keybars 6, these extensions 7 may be used as rails on which the laminations may be horizontally inserted into the stator frame.Type: GrantFiled: May 12, 2011Date of Patent: July 17, 2012Assignee: Siemens Energy, Inc.Inventors: Tom Majernik, James Bauer, Barry Sargeant, George Dailey

Patent number: 7302754Abstract: The present invention provides for a method and apparatus of horizontally stacking a stator core. A central rail structure 34 that runs down approximately the center axis of the stator frame 2, and attached to the central rail structure are adjustable supports 40 that hold the central rail structure within the stator frame. A dolly 36 is positioned on top of the central rail structure 34. The dolly 36 has multiple finger supports 38 disposed on its top and the finger supports match corresponding grooves in stator core laminations 10. Lamination are placed onto the dolly, gaps in the lamination engage the finger supports on the upper inner diameter of the lamination. This allows for the lamination to be horizontally moved into place within the stator frame.Type: GrantFiled: January 7, 2005Date of Patent: December 4, 2007Assignee: Siemens Power Generation, Inc.Inventors: Tom Majernik, James Bauer, George F.

Patent number: 7202587Abstract: The present invention facilitates the placement of laminations 10 onto keybars 6 of stator generators frames 2. Laminations need to be tightly fit onto keybars 6, however, the same need for tightness makes stacking laminations onto keybars particularly onerous. This is magnified when donuts, which are preassembled groups of laminations, are attempted to be stacked onto the keybars 6. The present invention provides for enlarged grooves 12 that more easily accept the keybars. This makes stacking laminations, both individually and in donuts, much easier. The laminations are then held in position by the insertion of a wedge 16. The wedge may be placed to disperse forces 20 transferred to the laminations in a circumferential manner 22.Type: GrantFiled: January 7, 2005Date of Patent: April 10, 2007Assignee: Siemens Power Generation, Inc.Inventors: John Barry Sargeant, Alex Christodoulou

Patent number: 6321439Abstract: A stator assembly method is disclosed for constructing a generator stator in the field. For stator assembly, the method includes the steps of positioning a stator frame on an assembly site; inserting a plurality of stator core modules into the stator frame; clamping the stator core modules together to form a stator core, attaching the stator core to the stator frame; and, winding a plurality of coil windings into the stator core. The stator may be positioned substantially vertically or horizontally at various steps in the method. The stator assembly method may also employ an assembly base to facilitate construction of the stator in the field.Type: GrantFiled: February 4, 1999Date of Patent: November 27, 2001Assignee: Siemens Westinghouse Power CorporationInventors: David B. Berrong, John Barry Sargeant, Calvin L. Paris, Gurdev Singh

Patent number: 6201334Abstract: An improved stator core and process for manufacturing the core are accomplished by a modular stator core design. The stator core is comprised of a series of equally sized and shaped stator core modules that are manufactured via a vacuum pressure impregnation process. The prefabricated modules can then be assembled into a stator core in an efficient way, saving several days of stator core assembly time. Moreover, a variety of stator core lengths can be accommodated by only inserting the required number of modules into the stator frame.Type: GrantFiled: January 6, 1999Date of Patent: March 13, 2001Assignee: Siemens Westinghouse Power CorporationInventors: John Barry Sargeant, Gurdev Singh, Calvin L.

Patent number: 6144129Abstract: A support system for an electric generator having a tapered spring bar connected between the stator core and stator frame, where the spring bar has a continuously tapered cross-sectional area along its length. The tapered cross-section provides a larger cross-sectional area at points having high bending moment and a smaller cross-sectional area at points having low bending moment. By eliminating material in areas of low bending force, a robust support system having increased flexibility is provided. The spring bar may further be formed from a plurality of thinner laminations, thereby providing the support system designer with an additional degree of flexibility for independently controlling the natural frequency of the supports in the radial and tangential directions.Type: GrantFiled: April 22, 1999Date of Patent: November 7, 2000Assignee: Siemens Westinghouse Power CorporationInventors: Robert Allen Fuller, John Barry Sargeant, Derek Wayne Green

Patent number: 6091177Abstract: A support system for an electric generator having a spring bar connected between the stator frame and a vertical spring plate mounted on a foundation. The spring bar provides flexibility in the tangential direction to minimize the magnitude of torque loads transmitted to the foundation during short circuit operating conditions. The spring plate provides flexibility in the radial direction to minimize the magnitude of vibration loads transmitted to the foundation during normal operating conditions. The combination of a spring bar with a spring plate allows the support system designer to optimize the natural frequency of the support system in both the tangential and radial directions.Type: GrantFiled: March 22, 1999Date of Patent: July 18, 2000Assignee: Siemens Westinghouse Power CorporationInventors: Luis Enrique Carbonell, John Barry Sargeant, Lon W. Montgomery

Patent number: 5926939Abstract: In an electrodynamic apparatus, a method of securing a coil basket of the type that includes a plurality of top coils and a plurality of bottom coils to a bracing assembly that includes a plurality of support braces includes steps of banding the top coil, the bottom coil and the support brace to each other; positioning a number of inflatable bladders, respectively, between the top coils and the bottom coils in the location of the bandings; and simultaneously inflating the bladders to a predetermined pressure that is sufficient to tension the bandings to a predetermined force, whereby forces that are transmitted to the coil basket from such inflation are imparted evenly throughout the coil basket and at the same time. An improved end winding region support system is also described.Type: GrantFiled: July 14, 1997Date of Patent: July 27, 1999Assignee: Siemens Westinghouse Power CorporationInventors: Kevin Joseph Konrad, David Norwood Dorsey, John Barry Sargeant

Patent number: 5767602Abstract: A fluted stator frame for an electric generator is provided. The fluted stator frame has a frame shell, a plurality of flat plates, a plurality of inner frame rings and a plurality of revised axial spring bars. A stator core is connected to the inner frame rings by means of the revised axial spring bars. The inner frame rings are connected to the frame shell by means of the flat plates. Each flat plate is slanted so that the plurality of flat plates are arranged in a truss formation. The spaces between the flat plates and the frame shell define gas flow ducts. The gas flow ducts provide a path for a flow of cooling gas to remove heat from the stator core of the generator.Type: GrantFiled: February 13, 1997Date of Patent: June 16, 1998Assignee: Westinghouse Electric CorporationInventor: John Barry Sargeant
