ABSTRACT:
A superconducting generator rotor which has a superconducting field coil cooled by liquid helium. The evaporated gas helium is utilized to cool the electric lead which leads electricity to the field coil. The gas helium is then confined in a coolant flow passage made of electrical insulation material. With this rotor, electrical discharge is avoided even when high voltage appears through introduction of excitation control.
