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. Suited for plant maintenance personnel as well as motor repair shops, the handbook is available in PDF format for free downloading at www.est-aegis.com/bearing.
