O.

In this paper, the finite-element method (FEM) is applied to determine from 2-D static electromagnetic field solutions the parameters representing this phenomenon. A specially designed synchronous machine that can be excited from both its direct and quadrature axes is used in this study in order that the parameters representing the cross-magnetizing effect could be measured experimentally and, thus, the accuracy of the numerical solution can be verified. The effects of some of the factors that may affect the accuracy of the FEM analysis have also been investigated. The results of these studies have shown that the calculated parameters representing the cross-magnetizing phenomenon using the FEM are consistent with the measured values.
