1. A testing apparatus for an active current control-type non-contact superconductive exciter, the testing apparatus comprising:
a non-contact exciter rotor including a rotor having a high-temperature superconductive coil part on one side and a second-generation high-temperature superconductive tape (HTS tape) part on another side and configured to rotate around an axial line by a drive motor; and
a non-contact exciter stator including a ring-shaped ferrous stator and a plurality of hybrid magnets,
wherein the non-contact exciter stator is placed at a distance in an outer circumferential direction relative to the rotor having the second-generation high-temperature superconductive tape part, and the plurality of hybrid magnets is mounted at regular intervals on an inner circumference surface of the ferrous stator,
wherein each of the plurality of hybrid magnet includes a permanent magnet, an inner electromagnet and an outer electromagnet,
wherein the permanent magnet is placed at a frontmost position based on a circular center point of the ferrous stator to generate a static magnetic field, the inner electromagnet is partitioned based on an insulation plate and is provided behind the permanent magnet to be connected to neighboring inner electromagnets, and the outer electromagnet is partitioned based on the insulation plate and is provided behind the inner electromagnet to be connected to neighboring outer electromagnets.
