1. An electrical generator comprising:
a stator, the stator comprising:
a plurality of high-temperature superconducting (HTS) magnets configured to generate a first magnetic field;
a stator coil having a first plurality of coils configured to generate a second magnetic field;
a rotor comprising:
a second plurality of conductive coils, the rotor configured to rotate so that the conductive coils move through the first magnetic field generated by the plurality of HTS magnets to produce electrical power; and
a third plurality of conductive coils coupled in series with the second plurality of conductive coils and positioned to rotate through the second magnetic field; and
wherein the first plurality of coils of the stator coil and the third plurality of conductive coils are positioned closer to a centerline of the electrical generator than the plurality of HTS magnets and the second plurality of conductive coils.
