Abstract: A generator including a frame (56); first and second frame rings (13) extending radially inwardly from an inside surface of the frame (56); a core (54) within the frame (56); key bars (100) spaced apart circumferentially and extending axially spanning a distance between the first and second frame rings (75A and 75B), the key bars coupled to the core; laminated spring bars (60) spaced apart circumferentially and extending axially to span a distance between the first and second frame rings, a first spring bar end (112) supported by the first frame ring (75A), a second opposing spring bar end (111) supported by the second frame ring (75B), each spring bar coupled to a key bar; wherein the laminated spring bar further includes spring bar subcomponents (60A and 60B) and couplers (98/99) for coupling the spring bar subcomponents.

Abstract: A technique for securing a group of stator packs that are part of a stator core to construction bolts associated with a generator frame. The technique includes using a single wedge set to secure the group of stator packs to each construction bolt. Each wedge set includes a solid filler piece positioned within a groove on one side of a notch in the stator pack and a construction bolt filler piece having a convex shape portion configured to the shape of the construction bolt that accepts the construction bolt. A wedge member is forced between the filler pieces to secure the group of stator packs to the construction bolt.
