Abstract

In order to meet the specifications of an electrical apparatus, the designer must be able to analyze and modify several fields of interest such as the electromagnetic fields, with the ultimate aims of safety, reliability, simplicity, efficiency and economy. The numerical finite-element method is proving to be an accurate, economical and useful design tool for the field analysis in electrical machinery. This paper presents briefly the formulation of the finite-element technique for solving two- and three-dimensional field problems in nonlinear devices, and reviews various applications made so far, while putting forth some new developments. These developments along with the progress made thus far in implementing the finite-element method show immense promise.
