Composite Ceramic Superconducting Wires for Electric Motor Applications
Abstract
A scaled-up process for producing sintered, silver-coated YBCO mono filament wire has been developed and is currently able to produce 30 meters of wire/day. Efforts aimed at improving the electrical performance of this wire are well underway. Two approaches are being used: (1) Continuously melt-texturing sintered YBCO wire/fiber to produce a macro-crystalline, strong-linked wire, and (2) Adapt the TBCO process to the production of BiSCCO wire which can be subsequently mechanically textured by rolling the wire into ribbon. Work has also proceeded on the fabrication of a brushless DC trapped flux motor in which melt-textured YBCO rings are used as permanent magnet replicas. This motor design holds the potential for a high power HTSC motor which can be fabricated using current HTSC technology. (r.h.)
