Electro Static Technology product offering
Product offeringCore offering
Electro Static Technology manufactures and sells AEGIS® Shaft Grounding Rings, which are physical ring devices installed on electric motor shafts to safely divert VFD-induced shaft voltage to ground and prevent electrical discharge machining damage to motor bearings. The portfolio includes SGR rings for motors under 500 HP, the uKIT universal mounting system, PRO Series for large motors and turbines over 300 HP, and EV/EVO rings for electric vehicle motors, along with installation accessories and a 2-year extended warranty.
Product overview
Electro Static Technology manufactures the AEGIS® line of shaft grounding rings for electric motor bearing protection. The product portfolio centers on four core shaft grounding ring products: the AEGIS® SGR (standard ring for motors under 500 HP), the AEGIS® uKIT (universal bracket mounting system for common NEMA/IEC frames), the AEGIS® PRO Series (for large motors, generators, and turbines over 300 HP), and the AEGIS® EV/EVO Rings (for electric vehicles). Supporting products include shaft voltage testing equipment, conductive epoxy, grounding straps, and colloidal silver shaft coating. The company also offers a proprietary 2-year extended warranty against bearing fluting damage and provides comprehensive technical documentation including the AEGIS® Bearing Protection Handbook. The technology uses conductive microfibers with patented FiberLock™ channels to provide 360-degree protection around motor shafts, diverting harmful shaft voltage safely to ground.
