Abstract

In this paper, the parameters of a transmission-line model for electrical machine windings are calculated on the basis of a finite-element model of the winding cross-section. Three finite-element formulations are compared: a low-frequency approximation, a high-frequency approximation and an eddy-current formulation. Combining wires into windings and the connection of parts in series or parallel is treated on the level of the transmission-line model. The application to a particular winding configuration indicates the validity ranges of the low- and high-frequency approximations in comparison with the eddy-current formulation. The propagating modes are examined.
