After transformation of motion equations and using averaging method, the approximate expressions for stationary and transient vibrations are derived. Owing to the non-ideal excitation, the unstable section of stationary response curve originates and causes jumps at transient processes. Influence of slope of moment characteristics and driving motor inertia on the range and level of instability domain is shown and discussed as well.
