On the use of a homogenization technique for the modeling of anisotropic magnetic material properties in a finite element analysis

The dynamical behavior of switched reluctance machines is mainly governed by the stator leakage inductance. A comparison of machine parameters, such as the ratio between the self and the leakage inductance, for constructions based on two different axial lengths are suitable for a deeper knowledge about the influence of the non-linear iron saturation effects within higher electrical currents. Therefore, 3D non-linear numerical field calculations are carried out in order to obtain the self and leakage inductances from a magnetic energy approach.
