EXPERIMENTAL SUPERCONDUCTING ALTERNATORS WITH IRON-CORE AND IRON-FREE ARMATURES,

Abstract

Iron-core and iron-free alternators employing super-conducting field windings have been designed and constructed. The design equations have been verified experimentally. The machines have been performance tested and their terminal characteristics obtained. Results indicate a need to carefully consider eddy current losses in copper conductors for designs in which the windings are exposed to peak magnetic flux changes. The advantages of using ferromagnetic materials in designs in which saturation flux densities are not encountered are illustrated. (Author)
