Current Diversion Ring Protects VFD-Controlled Motors
EP Editorial Staff | July 29, 2009
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 destroy the bearings. Inpro/Seal’s Current Diversion Ring (CDRTM, patent pending) safely diverts these currents and saves the motor bearings. Available through all major motor manufacturers worldwide, as well as EASA repair facilities, the new device can be furnished either 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.
