With the increasing use of variable-frequency drives (VFDs), there is increased generation of electrical currents on shaft motors, causing electrical damage to bearings. Manufacturers and end users ...

The AEGIS SGRâ„¢ Conductive MicroFiberâ„¢ shaft grounding brush improves the reliability of HVACR systems by extending motor life. By safely channeling harmful shaft current away from the motor ...

The static electrical charges produced by a turbine rotor create an effect akin to the one that results from dragging your feet across a carpet in the winter when the relative humidity is low. Touch a ...

A new 36-page, color handbook—the Aegis Shaft Grounding Ring Motor Repair Handbook—describes best practices for protecting motor bearings from electrical damage. Available from Electro Static ...

Aegis SGR Conductive MicroFiber Shaft Grounding Ring protects bearings from electrical damage. The conductive microfibers work with virtually no friction or wear, are unaffected by dirt, grease, or ...

Inverters used to control a motor’s speed or torque — also known as variable frequency drives (VFDs) or adjustable speed drives — can induce unwanted motor shaft voltages that cause premature motor ...

Electro Static Technology’s AEGIS WTG wind turbine grounding ring seeks to prevent bearing damage that could otherwise cause generator failure by safely channeling harmful shaft currents away from ...

ABB continues to increase the efficiency of its motors with the addition of a new motor variant to its ABB Baldor-Reliance SP4 motor line. These motors feature integrated shaft grounding technology ...

Electric motors fitted with variable frequency drives are at risk of bearing damage due to a build-up of current in the rotor that discharges through the shaft, damaging the lubrication and bearing ...
