Abstract
A superconducting electrical machine includes a rotor and a stator. The stator includes a stator having a plurality of circumferentially spaced radially extending teeth and a plurality of superconducting electric coils. Each superconducting electric coil is positioned around a respective one of the teeth. A thermally conducting member surrounds and contacts the stator. A cooler is arranged to cool the thermally conducting member. A vacuum enclosure encloses the thermally conducting member, the stator and the superconducting electric coils and a pump is arranged to evacuate the vacuum enclosure. The superconducting electrical coils include magnesium diboride.
