Abstract :
A fast hybrid modeling method is proposed for the 2D analysis of a linear flux switching machine. A magnetic equivalent circuit in conjunction with the boundary element method is applied to the geometry to accurately determine the airgap permeances. The model can also take into account the non-linear behavior of the soft magnetic parts of the machine. The force response obtained by the hybrid method is compared to those obtained by 2D finite elements. The force response shows good agreement in terms of amplitude and shape.
