USING MELT-TEXTURED YBCO FOR SUPERCONDUCTING ELECTROMOTORS

High-temperature melt-textured material prepared in a batch process wi th reproducible material parameters and properties can be used success fully to construct electromotors with an increased energy and force de nsity. A production process with high efficiency and moderate costs is the basis for the technical application of bulk melt-textured yttrium -barium-copper-oxide. The increased production rate also demands adequ ate characterization techniques that have to provide rite material par ameters needed for the specific application. The most suitable charact erization technique has to be chosen for routine characterization. Ii? this article, measurements were performed to simulate magnetic proces ses in electromotors. Functional models running in liquid nitrogen wer e constructed.
