Generator Field Machining

Some history in these photos, this General Electric generator stator is the oldest running generator in North America, it supplies power to the pumps in New Orleans to keep water out of the Levy, during hurricane Katrina the generator & turbine were damaged.

After the windings were removed it was found the laminant locating bars were out of position, Accurate Machine & Tool was contracted to line bore all the ribs and maintain a tolerance of .002 inches, and install (16) bars and maintain chordal tolerance of .005 inches.

This generator is the mate to the stator above, Accurate Machine & Tool was contracted to grind the journals, two generators can be very difficult to grind journals due to rotor flexing, we have designed a machine that will guide on the existing journal area and remains still while we rotate the rotor, this alleviates any possibility of changing rotor centerline. Journals dimensions are 16”inch OD x 32” inches long
