WE INTEND TO PROPOSE A MULTI-DISCIPLINARY PROJECT TO EXPLORE THE FEASIBILITY OF A CONCEPT FOR AN ORDER-OF-MAGNITUDE INCREASE INELECTRICAL MACHINE POWER DETTSITY EMPLOYING A TTOVEL SUPERCONDUCTING MACHINE ARCHITECTURE.SUPERCONDUCTING FLELD COILS WITH SIGNIFICANTLY HIGHER MMF CAPABILITY THAN CONVENTIONAL COILS OPENS UP A NEW DESIGN SPACE FORELECTRICAL MACHINES. ONE WAY TO UTILIZE THE LARGE MMF CAPABILITY IS TO MINIMIZE OR ELIMINATE THE USE OF FERROMAGNETIC MATERIAL ANDACCOMMODATE AND OVERCOME THE VERY LARGE MAGNETIC RELUCTAUCE (E.G. LOX). WITH THE IRON ATTD ITS SATURATION LIMIT GONE DESIGNS WITHMUCH HIGHER AIR-GAP FLUX DENSITIES CAN NOW BE GENERATED. UNFORTUNATELY EVEN THOUGH FIELDS THAT ARE 5 - LOX CURRENT LEVELS ARE POSSIBLEWITH SUPERCONDUCTORS EARLY DESIGNERS RAN INTO THE PRACTICAL CHALLENGE OF CONTAINING THE MAGNETIC FIELD EMANATING FROM THE MACHINE.TECHNIQUES EVALUATED SO FAR LEAD TO TRADE-OFFS THAT LIMIT POWER DEUSITY OF THE MACHINE. THIS TEAM RECOGNIZES A SIMILAR CHALLENGE INHIGH FIELD MAGNETIC RESONANCE IMAGITTG (MRI) MAGNETS ATTD BELIEVE ATT APPROACH USED TO ADDRESS THIS PROBLEM IU THOSE SYSTEMS ISAPPLICABLE ITT ELECTRICAL MACHITTES AS WELL - THE CONCEPT OF AN ACTIVE MAGNETIC SHIELD WITH SUPERCONDUCTING COILS. THIS TECHUIQUE EMPLOYSA SET OF MAIN COILS COMBINED WITH A SET OF BUCKING COILS THAT SERVE TO MINIMIZE THE EXTERNAL FIELD WITH ONLY A MODEST IMPACT ON THE FLELDIN THE REGION WHERE MACHINE TORQUE IS GENERATED. WE BORROWED THE BASIC CONCEPT AND ADAPTED THE TECHNIQUE FOR ELECTRICAL MACHINESAND HAVE OBTAINED EARLY RESULTS SUGGESTING SIGNIFLCANT IMPROVEMENT IN THE COMPACTNESS OF AIR-CORE SUPERCONDUCTING MACHINES.
