Abstract:

The program is for research contributing to new and improved electrical rotating machines, particularly in the area of superconducting motors. One possibility which is being examined is that for a low speed synchronous machine in which both the field and armature windings are superconducting. The design of such a machine is dominated by the A.C. losses which occur in the armature. Most superconducting wire for A.C. operation is a composite made of twisted superconducting filaments embedded in a normal metal matrix. Theory has been developed for the A.C. losses in such wire as a function of magnetic field and frequency over a wide range of conditions. The composite wire is treated as a continuum with anisotropic electrical conductivity. The results are used to design a conductor for a superconducting armature, and some tentative motor designs have been made. Author
