Computer-Aided Modeling and Prediction of Performance of the Modified Lundell Class of Alternators in Space Station Solar Dynamic Power Systems

By National Aeronautics and Space Administration

The main purpose of this project is the development of computer-aided models for purposes of studying the effects of various design changes on the parameters and performance characteristics of the modified Lundell class of alternators (MLA) as components of a solar dynamic power system supplying electric energy needs in the forthcoming space station. Key to this modeling effort is the computation of magnetic field distribution in MLAs. Since the nature of the magnetic field is three-dimensional, the first step in the investigation was to apply the finite element method to discretize volume, using the tetrahedron as the basic 3-D element. Details of the stator 3-D finite element grid are given. A preliminary look at the early stage of a 3-D rotor grid is presented. Demerdash, Nabeel A. O. and Wang, Ren-Hong Unspecified Center...
