Abstract:
1. A superconducting synchronous machine, comprising: a rotor having a shaft, a field core disposed on the shaft, a first inductor disposed on the shaft at one end of the field core, and a second inductor disposed on the shaft at the other end of the field core; a superconducting field coil having an annular shape with a superconducting wire wound around the field core of the rotor and for exciting with DC power; a refrigerant tank having the superconducting field coil installed in the refrigerant tank, the refrigerant tank containing a cryogenic refrigerant therein; a stator having an annular shape and disposed outside the rotor and the superconducting field coil; and a cryo-cooler coupled to the stator and in communication with the refrigerant tank for cooling the superconducting field coil with the cryogenic refrigerant.
