ABSTRACT:
An electrical machine with cryogenic cooling, comprising a superconducting field winding rigidly fixed to the shaft of a hollow rotor. The rotor is filled with a coolant which flows from the cavity of said rotor through heat exchangers mounted on the end face portions of the rotor. The design of the proposed machine provides for an increased effectiveness of thermal isolation of the superconducting field winding.
