ABSTRACT:
The process for stator bar rewinds includes disassembly of the stator bars at the generator site, measurement of the stator bars, forwarding digital representations of the measurements to a manufacturing center and forming 3-Dimensional models of the stator bars requiring replacement and the stator. The stator bar 3D model is placed in the stator 3D model to insure accuracy of fit. Tooling and stator bar drawings are generated and sample stator bars are manufactured. 3D modeling of the manufactured sample stator bars are compared to the nominal 3D models to insure accuracy. The replacement stator bars are manufactured and forwarded in batches for assembly into the extant generator.
