AVOID CATASTROPHIC BEARING FAILURE BY CONTROLLING STRAY SHAFT CURRENTS WITH THE INPRO/SEAL CURRENT DIVERTER RING (CDR). Electric motors that are controlled by variable frequency drives (VFD) may experience destructive, induced shaft currents that are discharged through the bearings, causing them to deteriorate and fail. These stray electrical currents can cause fusion craters, frosting, fluting and premature failure of the bearings. The Inpro/Seal CDR prevents catastrophic motor failure by diverting stray shaft currents to ground, away from the bearings. It is maintenance-free, designed to last the normal lifetime of your motor and meet API 547 specifications. |
