Electromechanical Interactions in Multibody Systems Containing Electromechanical Drives

Electromechanical systems are characterized by interaction of electromagnetic fields with inertial bodies. Electromechanical interactions can be described by so-called constitutive equations.Constitutive equations describing the coupling of multibody dynamics with Kirchhoff‘s theory of electrical networks as a quasi stationaryapproximation of Maxwell‘s theory define discrete electromechanicalsystems, i.e. systems with a finite degree of freedom.Then, based on the principle of virtual work, motion equations can be obtained as Lagrange‘s equations in explicit form due to a unified approach. The motion equations can be generated automatically. Hence, all electromechanical interactions are correctly taken into account.Examples for a MAGLEV and a planar motor are given.
