Abstract :
The authors have fabricated a 20 kW fully superconducting AC generator in which both the armature and field coils are made of superconductors. Two different types of excitation system were selected and tested: a brushless excitation method consisting of a “magnetic flux pump” and a conventional excitation method equipped with a collector ring and brushes. The paper describes the experimental machine model and the comparison of test results between the two different types of excitation methods
