3-D finite element method for analyzing magnetic fields in electrical machines excited from voltage sources

Abstract

A method for analyzing 3-D magnetic fields and currents in electrical machines excited from voltage sources has been developed. It was obtained by expanding the 2-D finite-element method into three dimensions, using the A phi method. The basic idea and the finite-element formulation are described. The effectiveness of the method is shown by some application examples.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
