Abstract
A superconducting rotating machine having a cooler for a rotator is provided. The superconducting rotating machine includes a rotator wound with a superconducting coil, a stator enclosing the rotator and separated therefrom by a predetermined gap, the cooler having a cold head directly attached to the rotator and at least one compressor connected with the cold head, and a flexible coupling disposed between the cold head and the compressor and enabling a cryogenic refrigerant to flow therein. The cold head is directly connected to the rotator, and the cold head and the compressor are driven using the flexible coupling, so that it is possible to prevent vibration of the compressor and enhance cooling efficiency by thermally separating the cryogenic cold head from the compressor.
