Abstract

Magnetic hysteresis in the force of a prebiased E-core reluctance actuator is researched using three analysis methods. Simulations are performed with a 2-D/3-D finite-element method (FEM); and two semianalytic methods are evaluated, namely, a generalization of the classical Preisach model, 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 analytic models are examined by a comparison with force measurements performed with a piezoelectric load cell.
