Quick rotor removal and replacement

Save time and money

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


Plan ahead

Reduce uncertainty

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:

  • Fully tested
  • Wound with the latest enhancements
  • Thermally balanced
  • Ready to install

GE’s Exchange Rotor Program has been running for more than 20 years. How does it work? You can exchange generator fields that need maintenance or repairs for refurbished, off-the-shelf, pre-wound, and tested fields.

Consider your options

Is a generator rotor exchange right for you?

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.
