Electro Static Technology – ITW, manufacturer of the patent pending AEGIS SGR™ Conductive MicroFiber™ shaft grounding brush, released 74 new sizes with additional part numbers to cover any VFD driven AC motor with up to six inch (6") shaft diameters. The full parts list for all 137 individual sizes for shafts from 0.311" to 6.020" is available to down load at http://www.est-aegis.com .

When variable frequency drives (VFDs) are used to control AC motors, currents are induced on the motor shaft. These currents build up until they are strong enough to discharge through the bearings, causing frosting, pitting, and fluting. Over time, these discharges can lead to premature bearing failure and motor failure. The AEGIS SGR conductive microfibers provide the path of least resistance for shaft currents to discharge to ground and prevent bearing damage and extend motor life.

The patent-pending AEGIS SGR is maintenance-free, lasts for the service life of the motor, and is unaffected by dirt, grease, or other contaminants. Now with the expanded part numbers, virtually any VFD motor, regardless of size and horse power, can be protected by this innovative new solution to prevent electrical bearing damage.

AEGIS SGR™ is easily installed by sliding the ring over either end of the motor shaft and locking it in place with simple screw-on mounting brackets. Because no machining is required, the SGR can be installed in minutes — even in the field.

Electro Static Technology is the global leader in the elimination and/or mitigation of induced electrical charges on rotating and moving surfaces. Other products include FLX-P™ flexible peel-and-stick passive static eliminators for printers, copiers, and other imaging devices. Electro Static Technology is a division of Illinois Tool Works (ITW), a $10 billion multinational conglomerate operating in 44 countries.
