Rotor member for a superconducting generator
A rotor is provided for an alternating current generator having a superconducting field winding. The rotor consists of a cylindrical outer member and a cylindrical inner member disposed coaxially inside the outer member. The inner rotor member carries a superconducting field winding and is cooled to maintain the winding temperature at superconducting temperatures during operation. The inner rotor member is rigidly attached at one end to the outer member and at the other end, which is the drive end, a connection is provided between the inner and outer members which has sufficient axial flexibility to allow large differential thermal expansion and contraction of the inner member, and which has sufficient torsional stiffness to transmit driving torque between the members. The flexible connection is preferably a laminated structure made up of thin slotted laminations having elements extending radially between the two rotor members and a driving connection to the inner member.
