Repair Capabilities

customized repairs for long-term solutions

At HECO, we don't believe in off-the-shelf solutions to electric motor repair. That kind of approach might fix a problem now, but won't prevent it from happening again. And you have better things to do than to chase the same repair problem time and again. So before we start any repair, we ask "Why." Why did the failure occur? What can be done to keep it from occurring again? Only then will we begin the repair. And our capabilities there are second to none.

Our electric motor repair shop capabilities and services include:
  • Rewinds with Vacuum Pressure Impregnation (VPI) to ensure a void-free, cooler-running, longer-lasting electric motor winding
  • Quality reconditions that increase motor life and prevent failures
  • Computerized diagnostic equipment that provides accurate and complete testing of the electrical components within an electric motor or generator
  • Stationary and portable motor repair equipment in order to repair in-house or on-site
  • Testing capabilities of up to 13.8kV, 4000kVA, enabling us to apply full voltage to a motor, thereby simulating the full-voltage environment that exists within a given plant
  • Computerized vibration spectrum analysis on an isolated test stand that yields true vibration readings on the motor individually, which can then be compared to the motor's in-plant performance
  • Dynamometer testing up to 2,200 ft-lbs that allows us to apply a load to your electric motor, further simulating how the motor will run when it is installed at the plant
  • An in-house machine shop to manufacture parts that meet or exceed the original manufacturer's specifications
  • Large Electric Motor Repair: Lathe machining capabilities up to 79" swing, 20' long, at 64,000 lbs, so we can repair the largest of rotating components within an electric motor or generator
  • Demagnetizing and degaussing equipment that allows us to remove residual magnetism from electric motor shafts, journals, bearing housings, etc.
We have the range of capabilities to perform these services on:
  • AC & DC Horizontal & Vertical NEMA Motors
  • AC & DC Horizontal & Vertical Above NEMA Motors
  • Synchronous Horizontal & Vertical Motors & Generators
  • Wound Rotor Horizontal & Vertical Motors & Generators
  • AC & DC Generators and Exciters
  • Fan-Cooled, Weather-Protected, Non-Vented, & Drip-Proof Motors & Generators
