AC & DC Electric Motor & Generator Repair

IPS engineers and repair technicians have extensive experience with electric AC & DC motor and generator repair, including hydroelectric generators, wind turbine generators, steam turbine generators, safety-related nuclear motors, main compressor motors, mill motors, underground mining motors, refiner motors and more.

We handle everything from NEMA and Above NEMA AC & DC motors (including 13 kV, 13.2 kV, 13.8 kV and 15 kV) providing premium engineered insulation systems, engineering services, materials upgrades and modifications when you need increased reliability with more horsepower in the same footprint. IPS also offers in-house coil manufacturing (up to 15 kV) for AC & DC motor and generator rewinding, to maintain single-source control over quality and lead times.

AC & DC Electric Motor & Generator Rewind Technologies

IPS offers three of the industry’s leading rewind technologies. Our premium engineered VPI insulation systems come with an industry-leading 5-year warranty. Their superior performance improves efficiency ratings and often permit design uprates. In addition to electrical performance improvements, mechanical modifications to enclosures, brackets, shafts, seals and bearings are available.

• MegaSeal™
  — Our premium high-voltage VPI insulation systems for HV motors and generators including 13 kV, 13.2 kV, 13.8 kV and 15 kV. Available on stators up to 14’ in diameter.
• EnduraSeal®
  — Our premium medium-voltage VPI rewind for motors up to 6.9 kV operating in severe conditions and harsh duty environments.
• IntegraSeal™
  — Our premium B-stage hard coil rewind designed for large and extra-large motors and generators. Ideal for onsite rewinds of turbine and hydroelectric generators, or stators greater than 14’ in diameter that are too large for VPI processing.
