Rotor Balancing is a type of analysis that compares the vibration profile with the rotation of a mechanical element to characterize inconsistent weight distribution around the diameter while calculating the amount and position of the weight necessary to offset the net imbalance.

Until recently, rotor balancing was a process that required a trained engineer. The process involved taking baseline measurements, graphically plotting on polar graphs, and calculating influence coefficients. Using Crystal Instruments’ handheld CoCo dynamic signal analyzer, the process has been largely automated. An operator can now perform a balancing operation simply and quickly using an automated process that instructs when and how to make changes to the system.

The CoCo-80 (and CoCo-90) dynamic signal analyzer and vibration data collector are recommended by Crystal Instruments for Rotor Balancing. The CoCo series feature an intuitive interface, 2 to 16 channel configurations, and excellent product support to guide users through all their testing needs, including modal testing.
