Generator rotor removal and replacement
With a generator rotor removal and replacement from GE, you can swap rotors that need repairs for refurbished, off-the-shelf rotors—an exchange we can perform in less than 10 days.
With GE’s generator rotor exchange, you’ll see removal and replacement in only 7 – 10 days, which is up to 30 days faster than an in-shop rotor rewind. On average, each day of reduced downtime translates to savings* of $30,000 to $130,000, depending on the time of the year the outage is performed.
*Average savings based on 100 to 175 MW units
You can order a rotor exchange as far in advance as you need to, substantially reducing the risk of schedule extensions and execution challenges due to late rotor parts, winding delays, or test failures that are common with an on-site generator. Your generator's new replacement rotor will arrive:
What are the most common signs of a faulty generator rotor? And how long does it take to repair a generator rotor winding? Find the answers to these questions and more in our interactive feature below—which covers topics from our recent webinar.
Did you know that GE is the OEM for thousands of generators? That includes many sub-models that most other vendors don’t have experience servicing, so we can work with you to make sure your new rotor is interchangeable with your old one. To date, we have performed more than 120 rotor removals and replacements for customers all over the world—including 30 just in the last two years.

There are a number of things to consider when planning your outage, from the age and future operation mode of your generator to the best timing for an outage for your plant and customers. GE can perform a risk assessment to determine the condition of your rotors, identify the ones most at risk and the type of rotor, and any spare generator rotor parts you might need.
In addition to rotor removals and replacements, we offer other services to help keep your generator running smoothly for its entire lifecycle.
If a rotor exchange isn’t for you, we also offer OEM in-shop generator rotor rewinds that include all available upgrades that use the latest F-Class insulation materials for the highest quality rotor rewind.
Available options include:
Having accurate operational and inspection data is key to avoiding an unnecessary outage. GE’s Generator Health Monitoring (GHM) software is a fully integrated, modular online monitoring suite that allows continuous condition assessment and early identification of any generator issues. With GHM in place, you will increase the reliability and availability of your generator, improve your outage planning, and reduce maintenance costs.
