Abstract

In this paper, a new approach for the numerical solution of coupled electromechanical problems is exploited with the aim of simulate electromagnetic devices with high-speed moving parts. The considered problem formulation rests on the low-frequency integral formulation of the Maxwells equations and the Newton-Euler rigid-body dynamic equations. The numerical integration of the coupled problem is discussed and developed with a two-step method. The method has been validated by comparison with experimental data (when available) and with results obtained by other numerical formulations. An example of application to a 2 degrees of freedom device based on permanent magnets is finally reported.
