A damper device for rotor of supreconducting generator

The present invention relates to a damper device for a rotor of a superconducting generator. The damper device for a rotary of a superconducting generator of the present invention includes an outer tube (100) formed in a hollow cylindrical shape and dampers (200) coupled to the outer tube in order to cut off alternating magnetic field generated in armature winding. The outer tube (100) comprises a plurality of longitudinal direction grooves (110) formed along the peripheral surface of the outer tube and the dampers (200) corresponding to the number of the longitudinal direction grooves (110) are sliding-coupled to the longitudinal direction grooves (110) respectively.
