AEGIS® (Electro Static Technology)
Variable frequency drives (VFDs or inverters) control motor speed or torque, matching changing loads while saving energy. But they induce shaft voltages that discharge through bearings, destroying them and shortening motor life. AEGIS® Shaft Grounding Rings channel harmful VFD-induced shaft currents safely to ground, eliminating unplanned motor failures and ensuring the reliability of critical building systems. They qualify as sustainable technology under the Federal Energy Management Program.
