Hts Motor Program at Oswald, Present Status

The present state of development of highly dynamic motors to be operated at 77 K (one HTS Linear Motor with superconducting double pancake stator windings and one four pole rotating synchronous motor with REM in the rotor, REM = rear earth magnets) is described. The final design of both machines is presented. The performance of BSCCO double pancake coils (dc, ac, and losses) is reported. Special considerations have been made with respect to cooling of the HTS tapes and cryogenic stability.
