Case Study: Rotor Solution Saves Customer $1.6M on Wind Turbine Encoder Repairs

PSI resolves an end-of-life rotor issue to cost-effectively repair wind turbine encoders

Overview: PSI Repair Services resolves end-of-life rotor issue to repair wind turbine encoders.

Solution: PSI Repair Services reverse-engineered the rotor and designed a drop-in replacement rotor to avoid retrofit costs to purchase new encoders.
Results: Over the last two years, PSI has been able to repair over 1,100 failed encoders with a PSI designed rotor. To date, this drop-in replacement solution has generated a cost savings of over $1,650,000 as opposed to the OEM alternative.
