IPS is the leading independent provider of repair and maintenance services for “Big Iron” — large and extra-large electric AC & DC motors and large and extra-large generators. We have more ways to test, repair, rewind, remanufacture and reverse engineer heavyweight electric motors and generators than anyone in the business, with extensive experience in the removal and installation of large, highly engineered applications.

Our regional service centers give us both local presence and a coast-to-coast service footprint, with the ability to scale quickly for regional and national support. Each IPS regional service center has a test stand and is a portal to IPS coast-to-coast resources, including heavy-duty lifting capability, high-voltage VPI rewinds and B-stage hard coils.
 

Electric Motor & Generator Rewind Technologies

IPS offers three of the industry’s leading rewind technologies for electric motors and generators. 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 up to 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.
