In this paper the variable mass rotor/fluid system is considered. A rotor with variable mass is settled in hydrodynamic bearings. The dynamic properties of the rotor on which the fluid force and the impact force (due to mass variation) act are analyzed. The conditions of stable rotation are obtained
