ABSTRACT:
Keybar slots in support plates of a large generator stator are made substantially oversize to accommodate the full probable distortion of the support plates occurring during fabrication of the stator frame. Keybars are affixed to pairs of auxiliary plates. The keybars are aligned within the oversize keybar slots, and then the auxiliary plates are affixed or welded to the stator support plates.
