VFD-Induced Shaft Currents Can Kill Your Bearings!
VFDs allow large energy savings and precise control. But they also generate electric voltages on motor shafts. These shaft voltages can discharge through the bearings, causing pitting, fluting, and eventual bearing failure.
Without bearing protection, shaft voltages can cause fluting damage.
Protect Motor Bearings with AEGIS® Bearing Protection Rings
By channeling VFD-induced discharges safely to ground, AEGIS® Bearing Protection Rings prevent electrical bearing damage. Proven in over a million installations worldwide, they provide unmatched protection of motors and coupled equipment from electrical bearing damage, motor failure, and unplanned downtime.
