blog details: The rotor is statically and dynamically balanced when it is assembled with blades. Each bladed disc is individually balanced prior to assembly for built-up rotors. Static balance means that the weight is evenly disposed around the axis of the shaft. It can be checked by rolling the rotor on horizontal knife-edge supports. Dynamic balance means that the moments of the out-of-balance weights along the axis about either bearing add up to zero. This is checked by spinning the rotor on resilient bearings, detecting the vibration, and adding or subtracting weights until the vibration is negligible. https://turtleturbines.com/different-types-of-steam-turbine-rotor-balancing/
