The present invention provides an apparatus for the horizontal stacking of laminationsand donuts to form a stator core. A stator generator framehas multiple keybarsthat run the axial length of the frame. The laminationshave groovesthere-in that engage the keybars to provide a secure fit of the laminations to the generator frame. By extending two or more of the keybars, these extensionsmay be used as rails on which the laminations may be horizontally inserted into the stator frame.

Method of horizontally stacking a stator core within a stator frame

The present invention provides for a method and apparatus of horizontally stacking a stator core. A central rail structurethat runs down approximately the center axis of the stator frame, and attached to the central rail structure are adjustable supportsthat hold the central rail structure within the stator frame. A dollyis positioned on top of the central rail structure. The dollyhas multiple finger supportsdisposed on its top and the finger supports match corresponding grooves in stator core laminations. Lamination are placed onto the dolly, gaps in the lamination engage the finger supports on the upper inner diameter of the lamination. This allows for the lamination to be horizontally moved into place within the stator frame.
