GE’s stator rewind services are standardized approach based on our deep, diverse generator heritage and knowledge. Stator Rewind services are a package of four modules: measurement*, engineering, bar manufacturing, and onsite rewind. Our proprietary processes and tools have been developed for quick, flexible execution across the value chain, with a focus on quality control at every stage.
*Applicable on other OEM generators
GE offers a range of availability and performance-boosting solutions, covering all cooling technologies, all generator sizes, and all OEMs.
Experience shows that typical operating incidents have the greatest impact on the field, which means the rotor is often the generator component requiring the most maintenance.
Whether the work you need is executed in a dedicated GE Generator Repair Shop or on site, GE provides a number of field rewind options to fit your needs.
With on-site rewinds you can benefit from reduced costs and fastest return to service.
For extended rewind scope such as upgrades you can rely on our repair shops equipped with high speed balancing pits.

bar removal
The rewind team were excellent in executing their duties, we lost time at the beginning of the project and they recovered significant amount of that time with no serious safety incident
High oil contamination created excess looseness, movement, and friction on the bars, which resulted in a gas into water leak on a bottom bar.
