Abstract

The present invention comprises a method and apparatus for installing a stator core, or portions thereof, into a power generator frame 2 that comprises assembling the stator core inside of a container 60 , and then moving the container to the power generator 1 . The container 60 is horizontally aligned with the power generator 1 , and the stator core is transferred from the container to the power generator.

Claims (12)

1. An apparatus for the horizontal placement of a stator core within a stator frame of a power generator, comprising:

a container, wherein said container comprises:

an internal space capable of holding said stator care;

a plurality of keybars arranged along said internal space capable of securing said suitor core within said internal space;

at least one vertical flange of said container and said stator frame including physical guides for indicating alignment of said container vertical flange with said stator frame vertical flange;

wherein said container is capable of being aligned with the stator frame and said stator core being disposed within said container is horizontally transferable to said stator frame.

2. The apparatus of claim 1 , further comprising keybar extensions, wherein said keybar extensions bridge said container and said stator frame.

3. The apparatus of claim 1 , further comprising a central rail structure, wherein said central rail structure is capable of supporting and aiding in the movement of at least one of laminations, donuts and a stator core within said container.

4. The apparatus of claim 1 , further comprising support rings, wherein said support rings are capable of applying a radial pressure to said plurality of keybars.

5. The apparatus of claim 1 , further comprising a powered transferring mechanism that is capable of aiding the transfer of said stator core.

6. The apparatus of claim 1 , wherein at least one of donuts and stator cores are capable of being assembled within said container.

7. The apparatus of claim 1 , wherein a stator core being disposed within said stator frame is horizontally transferable to said container.
