SUPERCONDUCTION ROTOR FOR GENERATOR AND MOTOR

摘要

PURPOSE: A superconduction rotor for a generator and a motor is provided to improve a reliability in case of a long-time driving and a tube current density of a field coil, and to drive the field coil in quasi-permanent current mode. CONSTITUTION: A superconduction rotor for a generator and a motor includes a superconductive field coil(100) to generate a revolving field by an outer driving source. A field coil supporting section(110) supports the field coil(100). A torque tube(120) connected to the field coil supporting section(110), transfers a rotary force generated from the field coil(100) to the outer. A rotor inner tube(130) around the field coil supporting section(110) is enclosed a rotor outer tube(140). A thermal shield board(160) is installed between the rotor inner tube(130) and the rotor outer tube(140). A refrigerant pipe(170) is connected with the rotor inner tube to supply a refrigerant into the tube(130). A refrigerant freezing means(180) freezes the supplied refrigerant. An exciter(190) excites the field coil(100) and moves the coil in quasi-permanent current mode.
