Prediction of magnetic hysteresis in the force of a pre-biased E-core reluctance actuator

Abstract

Magnetic hysteresis in the force of a pre-biased E-core reluctance actuator is researched. The simulations are performed with a 2d/3d finite element method (FEM) and two semianalytic methods are evaluated namely, the classical Preisach model (CPM), which is combined with a dynamic magnetic equivalent circuit (MEC) method, and a complex impedance model, which is combined with a static MEC model. Ultimately, the FEM simulations and analytical models are compared to force measurements performed on a piezoelectric load cell.
