Porównanie wyników elektromagnetycznych obliczeń polowych 2D i 3D dla jednostronnego indukcyjnego silnika liniowego

This article shows differences in results obtained by two way of FEM: 2D and 3D. Authors used one-side induction linear motor as a object for modeling. First part of the article describes the problems with 2D and 3D finite element modeling some special cases of the machine. Middle part shows the results of the electromagnetic modeling induction linear motor. The last part takes into consideration possible reason of the differences.
