Magnetic levitation (maglev) systems like magnetic monorail trains consist of electric, magnetic, and mechanic subsystems. Those three physical domains in such mechatronic systems interact with each other by the meaning of energy transformation in both forward and backward direction. By applying state-of-the-art approaches for modeling of magnetic systems it is not possible to create a consistent model of the maglev system combining all subsystems. For this reason, a novel multi-domain modeling approach is required to derive an integrated equivalent circuit incorporating all three domains. Based on energy considerations, representation of reluctance as capacitance is proposed in this article. Starting from analogies between electric, magnetic and mechanic state variables, universal representations of the parameters of all three domains can be defined for equivalent circuits. Using these representations, an integrated description of electromagnetic (e.g. transformators) and electromagnetomechanical systems (e.g. magnetic bearings) is possible.
