To
simplify the protection of bearings in VFD-driven
motors, Electro Static Technology has introduced the Split-Ring AEGIS(TM)
Bearing Protection Ring with Conductive Epoxy Mounting. Developed for fast,
easy field installation without detaching coupled equipment, the new Split-Ring
kit offers long-term protection of ac motor bearings from electrical damage, safely
channeling VFD-induced bearing currents
to ground. The unit has a 360-degree circumferential inner ring of conductive
microfibers permanently secured in place by the patented AEGIS
FiberLock(TM) channel. The FiberLock channel design not only prevents
the microfiber brushes from loosening or falling out, but also protects them
from breakage.
Unlike
conventional shaft grounding brushes, the ring is maintenance-free and lasts
for the life of the motor. It works with virtually no friction or wear,
regardless of motor rpm, and is unaffected by dirt, grease or other
contaminants.
