This document discusses rotordynamic analysis of vertical rotors using XLRotor software. It notes that for vertical rotors with fluid film radial bearings, the stiffness and damping of bearings depends on static load rather than gravity. Sources of static load include unbalanced magnetic pull, static hydraulic loads, partial admission loads, and static

These vibrations are broadly classified as synchronous( due to unbalance) or nonsynchronous such as caused by self excited rotor whirling. The three major areas of concern are rotor critical speeds, system stability and unbalance response. Critical speeds are the undamped natural frequencies of the rotor system.
