Inpro/Seal's Current Diveter Ring offers bearing protection for VFD-controlled motors
Inpro/Seal's Current Diveter Ring (CDR) offers bearing protection for motors using Variable Frequency Drives (VFDs) to adjust the speed output of Alternating Current (AC) motors. VFD-controlled motors inherently produce destructive shaft currents that must be redirected around the bearings. Otherwise, unmitigated electrical currents initiated by the VFD and induced by the motor shaft will destroy the bearings. The Inpro/Seal CDR safely diverts these currents and saves the motor bearings.
Inpro’s CDR components are made from corrosion-resistant bronze in any shape or configuration needed by the customer. The device will be available as a “press-in,” a “clip-on,” a “split” configuration or an “MGS” design, which prevents contamination from entering the motor bearing enclosure while diverting destructive shaft currents.
