CONDUCTIVE MICROFIBER SHAFT GROUNDING BRUSH
PROTECTS AC MOTOR BEARINGS
 MECHANIC
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.
