Usefulness of performing the transformation of the natural coordinate system, which describes the motion of an over-resonance vibratory machine driven by an inertial vibrator, into the rotating system related to an angle of an instantaneous position of a vibrator, was shown in the paper. The forms of equations-obtained in such a way-enable their more effective quality analysis, especially when this analysis concerns the number and location of stationary points. The algebraic equation for the determination of stationary points was formulated in the paper. On the basis of expanding this equation near natural frequencies the critical value of the driving moment, which allows passing through the resonance zone without the rotor stall, was determined. The results of the theoretical analysis were illustrated by the numerical examples.
