Superconducting Electrical Machines

摘要

A superconducting electrical machine has rotor and stator assemblies. A first rotor assembly is located to rotate within a stator assembly and is spaced from the stator assembly by an air gap. A second rotor assembly is located to rotate outside the stator assembly and is also spaced from the stator assembly by an air gap. The first and second rotor assemblies have at least one superconducting field winding. The superconducting field windings are formed from a High Temperature Superconducting (HTS) material such as BSCCO-2223 or YBCO, for example. The double rotor assembly configuration provides a new technical effect over conventional rotating superconducting machines having a single rotor assembly.
