Abstract:
A superconducting rotating machine comprising:a stator assembly; and a rotor assembly configured to rotate within the stator assembly and spaced from the stator assembly by a gap, the rotor assembly comprising: at least one high temperature superconducting winding assembly which, in operation, generates a magnetic flux linking the stator assembly;. and a cryogenic cooling system for cooling the at least one superconducting winding assembly of the rotor assembly; wherein the at least one superconducting winding assembly has an axis extending from a first end to a second end of the winding assembly, the winding assembly comprising: a plurality superconducting coils at least one of the plurality of superconducting coils having a superconductor tape wound about and disposed along an axis of the winding assembly to provide a plurality of concentric turns defining an opening, each turn of the superconductor tape having a broad surface maintained substantially parallel to the axis of the winding assembly; and a plurality of internal support members positioned between adjacent ones of the plurality of superconducting coils, wherein a laminated stack is created alternating between a superconducting coil and an internal support member.
