In this paper a method to consider saturation
behavior of induction machines during the finite element (FE)
analysis of high frequency excitations is developed. This
saturation behavior manifests itself in an additional saturation
and intermodulation harmonic, when evaluating the current
response related to a high frequency voltage excitation. In order
to correctly reproduce these harmonics within FE-analysis, the
fundamental wave as well as high frequency magnetic properties
of the lamination material must be represented in correct
proportion. To achieve this, relative permeability is adjusted to
create asymmetries in the high frequency magnetic properties.
An adaptation method for the transient permeability based on
the fundamental wave flux level was developed. Comparison of
measurement and FE simulation shows good agreement of all
main high frequency modulations present in induction machines.
