The differential inductance and flux linkage positional derivative are important parameters in the analysis and simulation of electrical machines where saturation is nonnegligible. A new method for the computation of these quantities for devices with an arbitrary number of windings is presented. The method is based on the determination of the sensitivity of the magnetic vector potential to variations...
In this paper, finite element (FE) field models for the calculation of resistance, inductance and capacitance in high voltage machine windings are developed. The models take into account frequency-dependent phenomena such as the skin and proximity effects and the magnetic flux penetration into the iron core. The accuracy of the electrical parameters calculated with the field models was verified by...
