Abstract

The present invention provides an apparatus for the horizontal stacking of laminations 10 and donuts to form a stator core. A stator generator frame 2 has multiple keybars 6 that run the axial length of the frame. The laminations 10 have grooves 12 there-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 6 , these extensions 7 may be used as rails on which the laminations may be horizontally inserted into the stator frame.

Claims (6)

1. An apparatus for horizontally assembling a stator core comprising:

a plurality of keybar extensions comprising at least one of a screw-in prosthetic and a tongue in groove prosthetic;

a plurality of keybars, wherein said plurality of keybars are part of a stator frame, wherein said stator frame has two ends and wherein said plurality of keybar extensions are attached at a first end of said stator frame to at least two of said plurality of keybars; and

a plurality of slide pads disposed on top of respective ones of the plurality of keybar extensions;

wherein laminations placed on said apparatus engage said slide pads on the outer diameter of the laminations.

2. The apparatus of claim 1 , wherein the laminations comprise a lamination donut.
