Geometric modeling and electromagnetic analysis of electrical windings for pulsed alternators
MetadataShow full item record
Pulsed alternators are state-of-the-art machines that require analytical design tools with a high level of fidelity. To meet the design needs, accurate modeling and analysis methods of the electrical windings of the machines have had to be developed. This paper will present a technique for creating accurate geometric models of racetrack style electrical windings, as well as a means of using these models to perform electromagnetic load analysis of the windings. This will begin with discussion of how one would convert a two-dimensional developed layout of a racetrack style winding into a full three-dimensional model. Using a similar technique, a model can be created for use in an electromagnetic (EM) analysis package. The results from this analysis can then be used to apply the resulting loads back onto the geometric model for mechanical analysis.
