Abstract :
We report here on the development of HTS coils at Intermagnetics for the Navy´s homopolar motor/generator program. Two coil sizes were used. A series of small test coils (14.0 cm i.d./spl times/15.0 cm o.d./spl times/1.4 cm long) were employed to evaluate various conductor winding, insulation and epoxy impregnation issues. Based upon the results of these test coils, the larger coil modules (19.37 cm i.d./spl times/24.35 cm o.d./spl times/2.54 cm long) for the homopolar motor/generator were fabricated. Several coils each of three types of react-and-wind coils were produced, one type with monocore BSCCO-2223, one type with multifilamentary BSCCO-2223 and the other type with surface coated BSCCO-2212. Test results are presented as well as discussions on various coil technology issues.
