ROTOR OF SUPERCONDUCTIVE ROTARY MACHINE

摘要

PURPOSE:To make efficiency concerning vibration and intensity of the rotor of a superconductive rotary machine to be favorable by a method wherein thickness of a damper support constituting a cold damper provided at the outermost circumference of the rotor is made as the center part thereof thicker as compared with the end part of the rotor. CONSTITUTION:The cold damper 4 is formed of a conductor 18 having function to shield a part of magnetic field reaching the rotor from the stator to be generated when sudden short-circuiting took place as to make the rotational direction and the rotational speed thereof not to synchronize with the rotation of the rotor, and of the damper support 17 having function as to make deformation and stress to be generated by electromagnetic force to samll. The damper support 17 is arranged at the outer side than the conductor 18, and the shape of the damper support 17 is so formed as the center part thereof to be thicker as compared with the end part.
