Abstract
A stator comprises a stator frame, a stator core and a spring. The stator core includes at least one lamination having a dovetail slot formed therein. A key bar is connected to the stator frame and includes a dovetail for engaging the dovetail slot. The spring is coupled between a portion of the lamination and the dovetail to provide an electrical ground path between the stator core and the stator frame. The spring includes a leaf spring that has first and second ends which contact the dovetail and a central portion. The central portion is connected to a base portion which contacts the lamination. Alternatively, the spring includes a base portion that contacts the lamination and prongs which project from the base portion and contact the dovetail.
