Influence of Iron Losses on Switching Dynamics of an Electromagnet from Experiment and Simulation

Abstract

The switching behaviour of electromagnets is determined by the inertia of the armature, the stiffness of the return spring and the magnetostatic forces between armature and yoke. For highly dynamic systems, hysteresis and eddy current losses have a slowing effect. In this paper we consider the experimentally observed behaviour of a switching magnet and compare it with simulation results including hysteresis and eddy current losses.
