A study of autoparametric vibrations of two degrees of freedom strong nonlinear system, when the excitation is made by an electric motor with unbalanced mass which works with limited power supply, is presented. The non-ideal source of power adds one degree of freedom, and then the system has three degrees of freedom. The system has been researched for known characteristic of the energy source (DC motor). The equations of motion have been solved numerically what permit to enrich the investigations and to examine not only small and steady state oscillations but also large-amplitude oscillations in transient states. In this paper the influence diferent kinds of spring and damping nonlinearities on energy transfer and regular and chaotic behaviour is investigating.
