Optimization and dynamical simulation are important tasks in the pre-sizing context. However it generally demands a large number of evaluations of the models frequently leading to a high computational cost. For this reason using finite element method (FEM) is prohibitive. In this paper, a new method able to solve non-linear magneto-static problems applied to numerical modelling of electromagnetic devices is used to pre-size actuators. A hybrid boundary element method (BEM) reluctance network method (RNM) based on scalar magnetic potential is used. Computational costs are lower than with FEM. This method presents several advantages for pre-sizing actuators.
In order to validate this method, a rotary actuator has been modelled. It consists of a permanent magnet, a coil and a nonlinear magnetic circuit. Comparisons with experimental results will be presented.
