Title: Composite ceramic superconducting wires for electric-motor applications. Quarterly technical report No. 6, 1 October-31 December 1989

Abstract

This report describes progress on developing YBa{sub 2}Cu{sub 3}O{sub 7-X} (Yttrium Barium Copper Oxide-X) wire for an High Temperature Superconductor motor. The wire development activity includes synthesis of Y-123 powder, spinning polymer-containing green fiber, heat treating the fiber to produce metallized superconducting filaments, and characterizing the electrical properties of the filaments. Green fiber is produced in lengths up to 1.5 kilometers. The green clad fiber is converted to silver-clad superconducting wire by a sintering operation. The sintered wire has a Amperes per centimeters squared (77 deg) up to 2800 Angstrom per centimeters in self field, dropping to low values in magnetic fields. Directional solidification efforts are underway to improve the critical current density. The construction of the first prototype HTSC homopolar motor is in progress. The design specifies a 575 ampere-turn HTSC coil. The current collection system has been tested in liquid nitrogen. Motor performance has been predicted based on actual Jc(B) behavior of wire samples. Motor power and losses have been calculated. The efficiency of this initial machine is limited by the magnetic fields obtainable from present HTSC wire coils.
