Industrial AC Motors Protected from Shaft Current: New AEGIS SGR Shaft Grounding Brush Boosts Motor Reliability

MECHANIC FALLS, Maine, March 7 /-- The new AEGIS SGR(TM) Conductive MicroFiber(TM) Shaft Grounding Brush from Electro Static Technology boosts reliability of AC motors controlled by variable frequency drives (VFD) in any manufacturing application. The patent pending AEGIS SGR protects motors from catastrophic failure caused by shaft current in motor bearings.

VFDs are increasingly used in industrial applications to control AC motors because of the tremendous energy savings and lower operating costs gained by the use of electronic drives for process control, pumps, air handling, rollers, spindles, extrusion machines, winders and many more applications. However, without a reliable grounding device on the motors, currents are induced on the motor shafts and typically discharge through the motor bearings, causing pitting, fluting and failure.

By protecting bearings from electrical damage for the life of the motor, the AEGIS SGR prevents costly motor failure, repairs and downtime. It is ideal for any industrial application where drives are used to control AC motors of any size from 1 HP to greater than 5000 HP. It is easily installed by sliding the brush over the motor shaft and locking it in place with simple screw-on brackets. Because no machining is required, AEGIS SGR can be installed in minutes -- even on the production floor.

Unlike conventional shaft grounding brushes which wear out quickly and lose their effectiveness, AEGIS SGR's conductive microfibers work with virtually no friction or wear and last for the life of the motor. No RPM limitations, maintenance-free and manufactured entirely from non-toxic materials, AEGIS SGR is unaffected by dirt, grease, or other contaminants and provides the longest-lasting protection available.

Electro Static Technology is the global leader in the elimination and/or mitigation of induced electrical charges on rotating and moving surfaces. Electro Static Technology manufactures the patent pending AEGIS SGR(TM) shaft grounding brush for the electric motor and generator industry and is a division of Illinois Tool Works (ITW), a $12 billion multinational conglomerate operating in 44 countries.
