HORIZONTAL SHAFT SUPERCONDUCTIVE ROTOR

摘要

PURPOSE:To reduce the peripheral temperature difference even if coolant in a rotor is irregularly presented by internally providing a conductive conductor on the inner peripheral wall near holes at both ends of a cylindrical coolant vessel. CONSTITUTION:A circular disc-shaped thermal conductor 15 made of copper or aluminum is provided inside a coolant vessel in contact with a flange 6a of a coil mounting shaft 6 at the end between a coolant vessel 3 and the shaft 6. The difference of upper and lower temperature of the shaft 6 to occur due to the invasion of heat from a torque tube can be equalized by the thermal conduction of the conductor 15 by providing such a conductor 15, and the difference of the upper and lower temperatures of the tube connected with the shaft 6 can be equalized.
