MOTOR SHAFT GROUNDING BOOSTS RELIABILITY
OF HVAC/R SYSTEMS
 MECHANIC
FALLS, ME - The new AEGIS® SGR Conductive MicroFiber Shaft Grounding
Brush from Electro Static Technology improves the reliability of
HVAC/R systems by dramatically extending motor life. By protecting
bearings from electrical damage for the life of the motor, the AEGIS® SGR prevents bearing noise and costly motor repairs and downtime.
It is ideal for OEM motor and fan manufacturers, repair shops, HVAC
service contractors, and in-house maintenance departments and can
be easily installed as part of a preventive maintenance program.
Detailed technical information is available at www.est-aegis.com.
When AC motors, commonly used in HVAC/R systems to drive fans,
air pumps, chillwater pumps, compressors, and other air-handling
equipment, are employed with variable frequency drives (VFDs), currents
are induced on the motor shafts. Without a grounding device, these
currents typically discharge through the motor bearings, causing
frosting, pitting, fusion craters, and fluting. This damage can
lead first to noise that travels throughout a building's ductwork,
then to motor failure, and finally to failure of the entire HVAC/R
system. By safely channeling harmful shaft current away from the
motor bearings to ground, the SGR prevents electrical bearing damage,
and the noise and motor failures it causes.
AEGIS® SGR is easily installed by sliding the brush 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, AEGIS® SGR's conductive microfibers
work with virtually no friction or wear and last for the life of
the motor, with no RPM limitations. Maintenance-free, the AEGIS® SGR is unaffected by dirt, grease, or other contaminants and provides
the longest-lasting protection available.
The SGR is available in standard sizes to fit most AC motors ranging
from 1 to 1500 HP with a full parts list available to download at
