ABSTRACT

An efficient iterative method is proposed for the computation of the actuation time of electromagnets. The proposed method solves the nonlinear equation of mechanical evolution using a numerical integration procedure. For various feeding curents and by varying the total weight of the mobile armature of a DC fed electromagnet, the actuation time was determined. The magnetic field was calculated with a numerical method, with a finite element software, for a convenient set of positions of the mobile armature, taking into account the nonlinear nature of the ferromagnetic material.
