CoolBLUE Absorbers for Motor Bearings

The Renown Electric team now offers CoolBLUE Inductive Absorbers that reduce damage to motor bearings and extend system life for each day of use.

Motor bearing currents are a damaging byproduct of variable frequency drive, or VFD, systems. Unfiltered, or without a “choke” mechanism, the system can suffer disastrous results:

  • Frostingcool-blue-absorbers
  • Bearing fluting
  • Lubrication breakdown
  • Electrical discharge machining (EDM)
  • Motor bearing failure

Common mode chokes such as CoolBLUE absorb damaging currents and protect motor systems. The inductor prevents energy and high frequency electrical signals from flowing into circuits where they could create unwanted results. Pathways and systems are thus protected from potential breakdown.

With protection from high frequency noise, equipment reliability is maximized, maintenance and its related costs are reduced, and unnecessary downtime is avoided.


Industries and Applications

The versatility of CoolBLUE cores offers an exceptional solution for a wide variety of industries. Examples include:

  • High Voltage Wires
  • Industrial HVAC
  • Multiconductors
  • Auto Manufacturing
  • Commercial and Office Buildings
  • VFD Manufacturerscool-blue-installation-2
  • Hospitals
  • Wind, Solar and Renewable Energy
  • Paper Manufacturing
  • Pumps and Fans
  • And more!

✓ Improve Reliability

VFD’s can create high frequency noise, which in turn can cause wear and unscheduled downtime. The CoolBLUE cores function as a common mode choke, actively absorbing this noise and helping to maximize reliability with reduced maintenance costs.

✓ Save Time

10 minutes to spare? That’s all the time it takes to install CoolBLUE cores around power cables. Disconnect, install cores, then reattach the power. It really is that easy.

✓ Save Money

A lifetime of performance, zero maintenance, and less than seven core sizes to fit all motor applications make CoolBLUE versatile, effective, and long-lasting — all while taking it easy on the budget.
