Abstract
Disclosed herein is a structure for cooling the stator of a superconducting rotating machine. The structure includes a stator coil. Slots are axially disposed at the stator coil to support the stator coil, and a space is defined between the slots to allow the stator coil to be partially exposed. A stator yoke is disposed on the slots such that a space is defined between the exposed portion of the stator coil, the slots and the stator yoke. A cooling tube is disposed in the space defined between the exposed portion of the stator coil, the slots and the stator yoke, thus simultaneously cooling both the stator coil and the stator yoke.
