What Is Rotor Balancing and Why Is It Essential? | Test Devices
Unlike rigid rotors, flexible rotors must be balanced in stages, starting with lower speeds and slowly working up to operating speed. Why Is Rotor Balancing Essential? High levels of vibration caused by unbalance can cause equipment to operate less reliably, which results in increased energy usage, decreased operational efficiency, and reduced ...

Rotor Balancing: Concept, Modeling and Analysis
Similarly, Fig. 5.1b illustrates a simple example for dynamic unbalance at the rotor discs where the masses are 180 out-of-phase to each other. The rotor can only be balanced using both balance masses and the relative phase angle positions unlike in static balancing where balance masses were directly placed opposite to unbalance positions.
