ABSTRACT:
A superconductivity rotor has a field coil portion wound with a superconductivity wire, a support portion for supporting the field coil portion, torque tubes positioned at both ends of the support portion and transmitting a torque to an outside from the field coil portion, an inner casing for housing the field coil portion and the support portion; and an outer casing for housing the inner casing and the torque tube. The torque tube consists of a first torque tube positioned at one end of the support portion and a second torque tube positioned at the other end of the support portion. The first torque tube is formed into a vessel shape and has a plurality of engagement holes formed along a periphery thereof so that it is engaged with an engagement member, and the second torque tube comprises a disc-shaped structure consisting of plural plates and main ring-shaped members stacked, and is engaged with an engagement member.
