Rotating Machinery Reliability for Technicians and Engineers

I first met Ron Brook at Reliance Electric Corporation in 1993. We had a bearing EDM issue with a specific Hermetic motor application and needed some assistance in the field. Ron worked in the services division of Reliance Electric and was highly recommended by another engineer in our group, William Miller. Ron determined that circulating current in the shaft from common mode voltage stresses induced by the VFD was the root cause of our bearing fluting. We were unable to replicate this until the motor was operating in an oil and freon environment.
