Abstract

The modern state of the electromechanical science is reviewed. State of the art in combined inductive-capacitive electromechanics is considered, and the fields of its possible practical applications and prospects for its further development are analyzed. A new approach for mathematical description of transients in dually conjugated dynamic systems is proposed, and the differential equations for combined inductive-capacitive electromechanical energy converters are derived proceeding from the proposed approach. The generalized Lagrangian theory of combined inductive-capacitive electric machines is developed as uniting the generalized Lagrangian models of inductive and capacitive electro-mechanical energy converters developed proceeding from the fundamental principles of binary-conjugate electrophysics. The possibility of optimizing an inductive generator’s operating mode using a capacitive generator with setting up a parallel or a series resonant circuit (with the interaction matrix serving as the controlling parameter) has been determined. The combined device is essentially a resonant machine, which has the best power performance indicators. The electrodynamic and electromechanical equations of combined inductive-capacitive electrical machines are given for the case when the structure of their excitation system contains ferroelectromagnets serving as dual-purpose active electrotechnical materials. The necessary Lagrangian for combined inductive-capacitive energy converters has been constructed by introducing a new matrix describing the interaction (mutual influence) between the inductive and capacitive subsystems. Simultaneous solution of these equations fully determines the dynamic behavior and power performance characteristics of the generalized model of combined machines of different designs and in any modes of interaction between their functional elements. It is shown that combined inductive-capacitive electromechanical converters have great prospects for use in microsystem electromechanics (for example, in microdrives at the level of nanotechnologies).
