  • Full-load testing through 4,500 HP @ 13.8 kV
  • IEEE 43 Insulation Resistance — Megger®
  • IEEE 43 Polarization index Ratio
  • IEEE 95 Hi-Pot AC/DC to 100 kV
  • IEEE 1043 Voltage Endurance to 13.8 kV
  • IEEE 1434 Partial Discharge
  • IEEE 1776-2008 Water Immersion to 13.8 kV
  • Doble® Test
  • Electromagnetic Core Imperfection Detector (EL CID)
  • PdMA Motor Circuit Evaluation (MCEmax)
  • Thermography
  • Ultrasonic testing
  • Vibration & Operational Deflection Mode Shape (ODMS)

Large & extra-large AC & DC motor and generator repair

IPS tests, rewinds, reverse engineers, and remanufactures large and extra-large electric motors and generators. We also redesign and rewind for uprating horsepower or efficiency.

Our engineers and design team handle frequency conversions, speed change rewinds, conversion to inverter duty, or voltage changes.

IPS in-shop repair capabilities include:

  • 145-ton lift capacity
  • VPI tanks at every service center, including the industry’s largest (14’ x 17’)
  • Dynamic balancing up to 80,000 lbs.

IPS offers the industry’s leading premium VPI rewinds.

Dedicated small electric motor repair

IPS maintains dedicated small electric motor repair cells across our North American network. These small motor repair specialists focus on low-voltage units up to 690 VAC.

We offer cost-competitive service with warranties and short lead times for:

  • NEMA motors
  • IEC motors
  • Arbor motors
  • Gear motors
  • Servo motors
  • Spindle motors
  • Low-voltage DC motors

In-shop service and repair for rotating equipment

IPS engineers and technicians work together on service, repair, and remanufacturing of gearboxes, pumps, fans, blowers, and compressors. We specialize in shaft, impeller, and weld repair for all pumps, from low flow to over 420,000 GPM.

We also provide coating, balancing, and new parts manufacturing. IPS service centers balance rotors up to 40,000 lbs., with static and dynamic balancing that meets ANSI and API specifications.

Our repair technicians bore out worn equipment housings, then sleeve to re-establish OEM dimensions and tolerances. We service, repair, machine, and remanufacture:

  • Shafts
  • Gearboxes and gear reducers
  • Pumps — Centrifugal, submersible, and vacuum
  • Clutches and brakes
  • Fans
  • Compressors
  • Blowers
  • Heat exchangers

In-shop test, repair, and reconditioning services for power distribution equipment

National Switchgear, now part of the IPS power management business, was a charter member of the Professional Electrical Apparatus Reconditioning League (PEARL). Our in-shop technicians specialize in surplus electrical equipment remanufacturing, rebuilding, and reconditioning.

IPS inspects, tests, disassembles, and restores circuit breakers, switchgear, and related parts. We test each completed product to OEM, PEARL, and InterNational Electrical Testing Association (NETA) quality standards.

Final inspection includes a 34-point visual inspection by the repair technician and QC supervisor.
