Single-source capabilities for wind power service

The IPS Wind Service Group provides single-source capabilities for fleets operating wind turbines during warranty and after warranty for the asset life of the machines. We handle generators, motors, rotating equipment, and power distribution systems.

IPS engineers, repairs, replaces, and remanufactures to minimize downtime and support run-time commitments. We solve problems inside the nacelle, at the bottom of the tower, and in the substation.

Up-tower service and repair

IPS field service technicians keep wind turbine work up-tower, to minimize crane costs and downtime. They handle all types of repairs, including slip rings, bearings, and precision machining inside the nacelle, plus:

  • Wye ring replacement
  • Generator shaft repair
  • Rotor lead change-outs
  • Generator change-outs
  • Pitch & yaw drive replacement

Our predictive and preventive maintenance help operators plan outages and minimize downtime. These services include:

  • Electrical testing — Baker Surge Test, MCE
  • Laser alignment
  • Vibration
  • Thermography


IPS now offers complete power distribution services, including transformers, switchgear, breakers, and custom panels. Learn more here.

In-shop wind power service and repair

We look at generators holistically during root cause failure analysis, then engineer for the fleet. IPS wind power repair services include:

  • Authorized OEM repair
  • Wind generators up to 4+ MW
  • Electric motors — pitch and yaw, cooling fans, hydraulic pumps
  • Transformers
  • Main breakers
  • Electronic boards

Mechanical repairs

We also offer complete mechanical repairs, including:

  • Authorized OEM repair
  • Wind turbine main shafts
  • Slip rings
  • Heat exchangers
  • Generator housings

WindGuard – The Class H rewind with a 60-year log life aging curve

IPS engineers addressed specific failure modes in this next-generation insulation system. WindGuard™ has the dielectric and mechanical strength to handle high-voltage transients and high-duty cycles.

Combine this with the IPS-engineered rotor connection system for a complete engineered solution.

The result is a wind turbine generator rewind that tests like a high-voltage rewind and comes with a five-year warranty.

Wind power distribution, manufacturing, and exchange

A short list of IPS wind power inventory includes:

  • Unit exchange generators
  • New generators
  • Replacement motors — pitch, yaw, cooling pump, and all metric motors
  • Complete yaw drive systems
  • Complete line of generator parts and components for all generator types
  • Circuit breakers and switchgear
  • Transformers
  • Lubricants

IPS has master distributor agreements with the leading OEMs. We also offer OEM-level manufacturing and generator exchange.

IPS has close working relationships with OEMs
