초록

Magnetic field distribution of rotating flux type Low-Tc superconducting (LTS) power supply with respect to the applied current on exciters is investigated in detail by using Finite Element Method (FEM). LTS power supply consists of two exciters, a rotor, a stator and superconductor foil attached to the inner surface of the stator and LTS load. The current pumping of LTS power supply is induced by partial-quenching and recovery of superconductor foil. For this reason, magnetic flux density on superconductor foil must be sufficiently greater than the its critical magnetic density. In this analysis, the normal spot on superconductor foil appears more than 10A of excitation current. The results of this analysis are calculated and compared with the experimental results.
