Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A stator core for affixing to a generator housing comprising: tabbed laminations stacked face-to-face to form a tabbed lamination module, each tabbed lamination comprising a first tab and a spaced apart second tab each extending from a circumferential edge of the lamination; non-tabbed laminations stacked face-to-face to form a non-tabbed lamination module, the non-tabbed lamination lacking any tabs; the non-tabbed lamination module stacked between…
