NECI provides CoolBLUE® inductive absorbers for any project where variable frequency drives (VFDs) are being installed, to protect motors from these stray currents.
Cool Blue Inductive Absorbers

VFDs create high-frequency currents that can damage motor bearings.

CoolBLUE® absorbs the damaging high frequency noise, so you can maximize equipment reliability, reduce maintenance costs, and avoid unscheduled downtime.
Your new bearings could look like this in just a few months without CoolBLUE®.
Common mode currents from VFDs can cause motor bearing damage, as well as electromagnetic interference that affects control signals, encoder feedback, communication links for PLCs, remote I/O, metal detectors, pump motors, and other types of sensors.
 
NECI provides CoolBLUE® inductive absorbers for any project where variable frequency drives (VFDs) are being installed, to protect motors from these stray currents.  For existing installations, we use vibration analysis to diagnose bearing wear from electrical fluting, and we provide services to replace bearings and install CoolBLUE® cores to prevent future damage.  

 

CoolBLUE® requires no motor modifications or shaft preparation, and installation is easy and can normally be completed in minutes.  This cost-effective technology eliminates the need for expensive hybrid bearings or specially insulated bearings, and lasts the lifetime of the system.
