ABSTRACT An axial gap superconducting electrical machine includes a housing, a shaft, bearing means in the housing for rotatably supporting the shaft, and at least one superconducting magnet assembly stationarily supported in the housing around the shaft. At least one armature assembly is mounted on the shaft in axially spaced alignment with the superconducting magnet assembly with the armature assembly including a plurality of coils mounted in slots in the assembly. The armature coils can be energized through slip rings on the shaft. The armature is made of non-magnetic material to reduce core loss. Yokes can be employed to confine magnetic flux, as needed, and in a single-ended stator design a back plate is used with the superconducting magnet assembly. The machine, in motor configuration, is fully adjustable in speed and torque and will provide full rated torque over the entire speed range.
