    The inductive absorbers help extend motor bearing life and reduce maintenance costs.

    Inductive Absorbers

    Renown Electric Motors & Repair now offers CoolBLUE Inductive Absorbers for motor bearings thanks to its recent partnership with MH&W International Corp. of Mahwah, NJ.

    The absorbers serve electric motors equipped with variable frequency drive (VFD) systems, which can create damaging motor bearing currents that often lead to lubrication damage and electrical discharge machining.

    If these issues are not corrected, full failure of the motor bearing and damage to the motor itself can occur.

    Cool Blue Absorbers

    CoolBLUE inductive absorbers, or common mode chokes, are easily installed around the power cables that run from a VFD to a motor.  CoolBLUE inductive absorbers “choke” the unwanted high frequency currents created by drives, filtering them out of the system before they cause damage. When installed, CoolBLUE inductive absorbers reduce noise, over-voltage peaks, circulating and motor bearing currents, and asymmetrical electromagnetic interference (EMI) currents, all created by VFDs.

    These absorbers help electric motors run more reliably and lengthen the motor’s lifespan. By controlling the damaging currents created by VFD systems, they also help to reduce downtime and costly maintenance.

    In addition to the new CoolBLUE product line, Renown Electric also offer a number of free design and installation guides for CoolBLUE products. The guides outline CoolBLUE features, types of equipment and applications for which the inductors are designed, and easy-to-follow installation instructions.
