High temperature superconductor generator with increased rotational inertia

A turbo-generator, comprising:

• a turbine;
• a shaft interconnected at a first end to the turbine;
• and
• a high temperature superconductor (HTS) rotating machine connected to a second end of the shaft and having a longitudinal axis;
• the HTS rotating machine, comprising:
• a cylindrical stator assembly disposed about the longitudinal axis;
• a cylindrical rotor assembly disposed within the cylindrical stator assembly and configured to rotate within the cylindrical stator assembly about the longitudinal axis, the cylindrical rotor assembly having a first rotational inertia and comprising:
• at least one HTS winding assembly which, in operation, generates a magnetic flux linking the cylindrical stator assembly;
• and
• a cylindrical electromagnetic shield disposed about the at least one HTS winding assembly, wherein the cylindrical electromagnetic shield has a second rotational inertia;
• and
• a cryogenic cooling system for cooling the at least one superconducting winding assembly of the cylindrical rotor assembly;
• wherein the second rotational inertia is at least eighty percent (80%) of the first rotational inertia.
