CONDUCTIVE MICROFIBER SHAFT GROUNDING BRUSH
PROTECTS AC MOTOR BEARINGS

Photo of Microfiber Shaft Grounding BrushMECHANIC FALLS, ME - The revolutionary new AEGIS™ Shaft Grounding Coupling (SGC - patented technology) from Electro Static Technology prevents electrical damage to bearings of AC motors by safely passing harmful shaft current to ground. Extremely effective yet low-cost, the AEGIS coupling provides an ultra-low impedance path from shaft to frame, allowing current induced by variable frequency drives (VFDs) to pass to ground without damaging motor bearings or the bearing race.

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, fusion craters, and fluting. Over time, these discharges can lead to bearing failure and motor failure. The AEGIS SGR (patented technology) provides an alternate path to ground for these shaft currents, preventing bearing damage and extending motor life.

The patent-pending AEGIS SGR Conductive MicroFiber™ Brush 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.

Unlike conventional shaft grounding brushes, which wear out quickly and lose their effectiveness, the AEGIS SGR's conductive microfibers work with virtually no friction and no wear and last for the life of the motor. There are no RPM limitations on the operation of the motor.

The SGR is available in 39 standard sizes to fit any NEMA motors ranging from 1 to 150 HP with shaft diameters from 0.775" to 2.395" (20 mm to 60 mm). Larger sizes up to 6" (150 mm) shafts are available by special order.

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.
