Increase bearing
reliability with Smart™ Technology
VFD – Motor
controllers induce high frequency voltages on the shaft that seek a
path to
ground. When these voltages exceed the lubricant’s ability to provide
insulation, they discharge the motor’s bearings or through the motor’s
bearings
of coupled equipment resulting in Electrical Discharge Machining:
- ·causing fusion craters on
the shaft
- pitting and frosting
and fluting on bearings
- premature bearing
failure in VFD driven motors
Even if a
motor has insulated bearings, shaft currents can travel to the coupled
equipment such as pumps, pillow blocks, and gear boxes and damage those
bearings. The results are often costly: reduced equipment
reliability,
increased maintenance costs, unscheduled downtime and in turn lost
revenue.
REDUCING
ELECTRICAL DAMAGE - While specifically designed bearings, grease,
carbon brushes, filter, and grounding rings have been introduced to
migrate shaft currents, each has significant limitations.
SMART™ SHAFT
GROUNDING - from INPRO/SEAL addresses the limitation of these other
technologies to effectively divert harmful shaft currents and increase
bearing and equipment reliability. Inpro/Seal offers the most reliable
method for diverting stray currents to ground.
