초록

This paper is a study on the rotating type of superconducting power supply(R.S.P.S.) with superconducting excitation coils. In this paper, a new idea of excitation coil is introduced to control the pole-flux in air gap. We manufactured the R.S.P.S. by using superconducting excitation coils and measured the charging current of superconducting load with respect to rotational speeds and excitational current. Through this experiment, 425A of maximum current was obtained a few minutes. It turned out that the charging rate of load current is proportional to rotational speeds and excitational current. Furthermore, it is found that it's possible to generate the charge current of thousands of amperes by using wires of larger critical current.
