An equivalent circuit in Fourier space for study of linear induction motors
Abstract
The authors (1978) have already shown that the study of longitudinal edge effects in linear induction motors (LIMs) can be greatly simplified by using an extension of the existing Fourier transform theory. The model considered was a single-sided LIM with a limited longitudinal patch of excitation and iron of infinite width and length. The present paper demonstrates that the equivalent multiregion problem can be modeled by utilizing a transmission-line analog in terms of the Fourier-transformed quantities. The process is straightforward and opens the way for the study of more complex problems. The model discussed has finite-length excitation with homogeneous layers reaching to infinity. The transmission-line analog with the transformed-field quantities provides considerable savings in time and effort.
