The object of this paper is to present asymmetric rotor and shaft models in rotating machinery systems. Using these models it is possible to analyze the electrical motors or generators which have different lateral stiffness or the moments of inertia in two orthogonal directions. The asymmetry causes unstable vibrations in some rotating speed ranges. A cracked shaft model is presented as the extension of the asymmetric shaft model. These models are implemented in our original rotating machinery library.
