Dynamic hysteretic effects of magnetic materials are usually neglected in actuators modeling. In order to take into account these effects, we coupled a two-dimensional finite-element (FE) model in an original way with a magnetic equivalent circuit by using dynamic hysteretic flux tubes (DHFT). As an example of an application, we present the model of an ultrafast switched reluctance motor, in which the control of the power converter is of major importance, and where iron losses can reach critical values.
