  • Turbine generator stator core attachment technique
    Patent number: 8941282
    Abstract: A stator core (105) including tabbed laminations (100) stacked face-to-face to form a plurality of tabbed lamination modules (107), with each tabbed lamination including a first tab (102) and a second tab (104) extending from a circumferential edge of the lamination. Non-tabbed laminations are also stacked face-to-face to form a plurality of non-tabbed lamination modules (109), each non-tabbed lamination lacking a tab. The tabbed lamination modules are stacked face-to-face in an alternating configuration with non-tabbed lamination modules. The tabs are used to attach the stator core to an inside surface of an electrical generator frame (2), such as by attaching the tabs to frame support rings (4) of the generator frame.
