초록
For the test of the operating characteristics as a moor, a 20 kVA super conducting synchronous machine with rotating field windings has been made in Saga university, Japan from 1991. Before the load tests of it as a motor, we carried out cooling down tests and measured its machine constants. During the cooling down tests, we found that the rotor itself had no cryogenic problem, but the inlet part for liquid He had one. Though enough liquid He couldn't be accumulated inside the rotor because of this problem, we drove field currents up to 20 A and could acquire the machine constants and V curves of the super-conducting synchronous motor.
