Grounding Coupling Prevents Shaft Current from Damaging 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 are used with AC motors, current
is induced along the motor shaft. When it overcomes the resistance
of the grease, this current discharges through the motor bearings
causing frosting, pitting, fluting, and fusion craters which can
lead to premature motor failure. With its patent-pending Electron
Transport Technology™, the Aegis coupling solves this problem
by providing a "virtual short" between the shaft and motor frame
that keeps shaft current and voltage from building up in the first
place. Easily installed and maintenance free, the Aegis coupling
is a reliable, low-cost alternative to less effective mitigation
schemes such as brushes.
In addition to eliminating damaging shaft current, the Aegis SGC
(patented technology) provides cleanroom-quality bearing isolation with
a dustproof seal that also protects against water spray. Developed
initially for 5 to 15 HP NEMA motors (the largest installed base
of motor/drive applications), the Aegis SGC is ideal for HVAC, cleanroom,
petrochemical, manufacturing, transportation, and other applications
where VFDs are used. Additional sizes will be available in the immediate
future.
Electro Static Technology is a global leader in the elimination
and/or mitigation of induced electrical charges. 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.
