Abstract
This paper discusses the dynamics of the simplest electromechanical system. The system is composed by two interacting subsystems, a mechanical and an electromagnetic. The system was chosen as simple as possible to highlight the mutual interaction between the two subsystems and to show that this interaction provokes an oscillatory response. Different from purely mechanical systems, here the oscillatory response does not occur due to an interplay of kinetic and potential energies. The system analyzed in this paper does not have elements that can storage potential energies, neither mechanical nor electrical. Natural frequency and normal modes are computed for the electromechanical system. The computed parameters involve mechanical and electromagnetic variables, i.e., they are hybrid, a novelty in the literature. Hybrid model coordinates, resonance and frequency responses graphs are discussed. An energetic analysis is developed. It is shown that the hybrid natural frequency determines the frequency at which occurs the interplay of energy between the mechanical and the electromagnetic subsystems.
