At higher speeds the shaft will deflect, due to the non symmetric circular cross section. Depending on the position of the discs on the shaft they can even be inclined and thus increase the oil whirl.<br> | At higher speeds the shaft will deflect, due to the non symmetric circular cross section.

An increase of the running quality is achieved through reduction of the asymmetry by means of addition or reduction of masses. Thus the inertial axis | An increase of the running quality is achieved through reduction of the asymmetry by means of addition or reduction of masses. Thus the inertial axis is moved to approache the rotational axis. Rigid rotors can be sufficiently balanced in one or two planes. In practice depending of the number of transducers used and the number of planes four cases can be considered. | ||
