New Technology Reduces Shaft

Currents and Resolves Bearing Fluting Issues!

Variable Frequency Drive Systems create damaging motor bearing currents. If these currents are not filtered or “choked,” bearing fluting, frosting, breakdown of lubrication, electrical discharge machining, and motor bearing failure can result.CoolBLUE® absorbs this damaging current before it gets to the motor.
- Maximize Equipment Reliability
- Reduce Maintenance Costs
- Minimize Unscheduled Downtime

CoolBLUE® inductive absorbers operate in a similar fashion as a common mode choke by absorbing the damaging high frequency noise associated with VFD’s. Maximize equipment reliability, reduce maintenance costs associated with
grounding rings, and avoid unscheduled downtime.Installation around motor cables takes less than 10 minutes. Simply disconnect the
cables, install the cores around the cables, and reattach. Done!Less than 7 core sizes fit all motor applications ( 1/4 hp to 1600+ hp ). CoolBLUE® inductive absorbers last a lifetime, and there is NO MAINTENANCE unlike motor shaft products subject to rust, dirt, grease, and worn grounding brushes.

CASE STUDY

Before CoolBLUE

Problem: Frequent Bearing Failures In Motors At a Children’s Hospital

An Indianapolis Children’s Hospital was experiencing an overwhelming amount of bearing failure. The root of the problem came down to bearing fluting due to shaft currents generated by the VFD. Horner, along with an engineer for CoolBLUE® conducted a field test and verified the current spikes. Horner installed four CoolBLUE® inductive absorbers and the common mode noise was significantly reduced by about 70-75 percent.
