Abstract
The need for design optimization and operational reliability of electrical machinery necessitates accurate performance prediction at the design stage. This in turn requires the detailed evaluation of the magnetic field distribution in the machine geometry. The finite element method offers a stable numerical solution technique with a good deal of precision. This method requires the formulation of the partial differential equations in variational terms or by a weighted residual procedure. In the case of the former an energy related expression called a functional is minimized with respect to a set of trial solutions. This paper describes the application of the finite element method to electrical machine modeling taking into account iron saturation, eddy currents in conducting parts and the distributed nature of materials and sources. Some of the areas surveyed are utility generators, skin-effect in busbars, eddy current losses in transformers, and others.
