How do you balance a wide rotor in relation to diameter and center hung?

The appropriate method for balancing a wide rotor, particularly in relation to diameter and centered hung configuration, is the two-plane method. This method is essential when dealing with large rotors, as it allows for a more comprehensive approach to balancing by taking into account the inertia of the rotor as it rotates.

In a two-plane balancing scenario, measurements are taken in two distinct planes of the rotor. This mitigates issues of static imbalance and ensures that both planes are adjusted to achieve optimal balance. By addressing both planes, the two-plane method addresses complex vibrational issues that can arise from varied rotor diameters and configurations, leading to improved performance and reduced wear on bearings and surrounding structures.

This method is especially effective for larger diameter rotors since static imbalances can have a significant impact on performance if not properly managed. It provides a thorough approach to distributing the mass more evenly, ultimately achieving a smoother operation. Dynamic positioning, which could be confused with the concept, primarily focuses on optimizing the rotor's position rather than achieving balance across different planes.
