Overhung rotor balancing

Webdamage the rotor by bending the overhang during these transients. The situation is aggravated during the normal balancing procedure due to the following two facts (i) the rotor is uncoupled from the turbine softening the overhang rigidity, and (ii) it is set in softer balance pedestals that shift the first few natural frequencies towards, and WebEI-300 Balancing Machine. EI-300 Dynamic Balancing Machine is designed to accurately balance rotors of any type. The length of its bedplate allows balancing rotors of up to 2 meters long to be mounted. Additionally, the EI-300 will allow you to make overhung rotor balancing thanks to its negative supports (optional). Minimum mass: 1 kg.
