Abstract
A model of a two-pole turbogenerator airgap region is developed in suf ficient detail to predict the unbalanced magnetic pull on the rotor, u nder no-load conditions, caused by static eccentricity. The effects of rotor magnetic saturation and eddy currents are taken into account us ing a set of rotor surface impedances. The computer program is relativ ely simple and extremely fast in computation time on a modest PC.
