ABSTRACT:
The present invention facilitates the placement of laminations10onto keybars6of stator generators frames2. Laminations need to be tightly fit onto keybars6, however, the same need for tightness makes stacking laminations onto keybars particularly onerous. This is magnified when donuts, which are preassembled groups of laminations, are attempted to be stacked onto the keybars6. The present invention provides for enlarged grooves12that more easily accept the keybars. This makes stacking laminations, both individually and in donuts, much easier. The laminations are then held in position by the insertion of a wedge16. The wedge may be placed to disperse forces20transferred to the laminations in a circumferential manner22.
