Abstract
Purpose
The purpose of this paper is to offer a simulation method for predicting the impedance of machine windings at higher frequencies.
Design/methodology/approach
A transmission‐line model (TLM) is developed based on parameters calculated on the basis of electroquasistatic and magnetoquasistatic finite‐element (FE) model of the winding cross‐section.
Findings
The FE formulations for the low‐ and high‐frequency limits give acceptable results for the respective frequency ranges. An eddy‐current formulation is only accurate on a broader region when the FE mesh is sufficiently fine to resolve the skin depth.
Research limitations/implications
The paper is restricted to frequency‐domain simulations.
Practical implications
The results of the paper improve the understanding of higher‐frequency parasitic effects in electrical drives with long windings.
Originality/value
The paper shows the limitations of the FE methods used for determining the parameters of the TLMs and remedies to avoid these.
