Variable frequency drives (VFD) on AC and DC motors induce harmful electrical voltages on the motor shaft. Once these voltages exceed the resistance of the bearing lubricant, they discharge through the motor's bearings causing fusion craters, severe pitting, fluting damage. Excessive bearing noise and eventually bearing failure is the result. The AEGIS SGR Bearing Protection Ring prevents electrical bearing fluting damage by safely diverting shaft voltages and bearing currents to ground, and dramatically extend motor life.
