Mechanic Falls, ME — 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 Technology, manufacturer of AEGIS® shaft grounding rings, the book explains how to diagnose electrical bearing damage caused by variable frequency drives (VFDs), also known as inverters. It then goes on to explain in detail best practices for preventing such damage to motors of various sizes and horsepower ratings. AEGIS Bearing Protection Rings channel VFD-induced bearing currents safely to ground. Continuous circumferential rows of conductive microfibers embedded securely in the ring’s patented AEGIS FiberLock channel completely surround the motor shaft and provide millions of discharge points for harmful shaft currents. This unique design creates the path of least resistance that effectively diverts these currents away from bearings to ground. The microfibers themselves are specially engineered for exceptional conductivity and flexibility to minimize wear and prevent breakage. AEGIS rings are the only long-term shaft grounding technology proven effective in hundreds of thousands of VFD/motor applications worldwide.
