ROTOR OF SUPERCONDUCTING ROTARY ELECTRIC MACHINE AND MANUFACTURE THEREOF

摘要

PURPOSE: To obtain a rotor outer tube, excellent in jointing strength and ease of assembly, that achieves sound jointing even if the diameter or axial length of a normal temperature damper is excessively increased. CONSTITUTION: A rotor outer tube 21 of three-layer structure is obtained by placing an inside and an outside damper supports 21b, 21c inside and outside a normal-temperature damper 21a, respectively and integrating them into one piece. A rotor inner tube for housing a cooling medium is coaxially placed in the rotor outer tube 21. Torque tubes formed at both ends of the rotor inner tube are secured on the rotor outer tube 21 to form the rotor of a superconducting rotary electric machine. The normal-temperature damper 21a comprising the rotor outer tube 21 is composed of a plurality of damper members divided in the circumferential direction.
