WebThe fault condition is common in DC motors, and it is now increasingly common to see this problem on variable frequency drives. Because of the "washboard" pattern on the bearing surfaces, a series of peaks is often seen clustered together up in a high-frequency band, typically between 100,000 CPM and 180,000 CPM. WebSep 29, 2024 · Fluting is damage caused to a bearing due to an electrical current induced on the shaft of a VFD (Variable Frequency Drive) machine. If a machine is rated at less than 100 horsepower, a carbon fiber brush may be attached to a shaft grounding ring (also called a split ring, solid ring, or a press fit) and installed on the drive side of the shaft. chinaman photo on 45th street https://chriscrawfordrocks.com
