Analysis of a Dynamical Electromechanical Model for Magnetic Bearings with Induced Currents

The purpose of this paper is to present a parameterized electromechanical model considering as well the electromagnetic nature of the forces acting inside a magnetic bearing as the general rotating machinery aspects, and their interactions. This model takes particularly the effect of induced currents into account. The inductive and resistive effects, as well as the skin effect taking place in the bearing are considered. The model is validated on an existing semi-passive magnetic bearing.
