Preventing VFD/AC Drive Induced Electrical Damage to AC Motor Bearings The use of variable-frequency drives (VFDs) to control AC motors has increased dramatically in AEGIS™ Bearing Protection Rings Overview The use of variable-frequency drives (VFDs) to control AC motors has increased dramatically in recent years. September 15, 2006 - Available in sizes to fit NEMA AC motors ranging from 1-1,500 hp with shaft diameters from 0.311-6.020 in., AEGIS SGR(TM) Conductive MicroFiber PREVENTING VFD/AC DRIVE INDUCED ELECTRICAL DAMAGE TO AC MOTOR BEARINGS Written by: William Oh, Engineer October 5, 2007 Currents are induced on the motor shafts when AC motors are employed with VFDs to drive air pumps, chillwater pumps and compressors in HVAC/R systems. MECHANIC FALLS, ME - The new AEGIS SGR(TM) shaft grounding brush from Electro Static Technology prevents electrical damage to AC motor bearings and extends motor life The use of variable-frequency drives (VFDs) to control ac motors has increased dramatically in recent years. In addition to their low operating cost and high To simplify the protection of bearings in VFD-driven motors, Electro Static Technology has introduced the Split-Ring AEGIS Bearing Protection Ring with Conductive

AegisÂ? Shaft Grounding Coupling prevents electrical damage to bearings of AC motors by safely passing harmful shaft current to ground. The cleanroom-quality When variable frequency drives (VFDs) are used to control AC motors, currents are induced on the motor shaft. These currents build up until they are strong enough to
