Abstract

A study on efficient excitation system must be important to enhance the potential of superconducting AC generators further. After the first successful demonstration in a feasibility of magnetic-flux pump based brushless excitation system suitable for superconducting generators in 1983 [1], we have been constructing a testing machine able to generate actual electric power. Concurrently with it, we have been studying a fully superconducting generator with both of armature and field coils made of superconductors.

The paper presents the experimental machine system and its testing results about pumping-up performances of magnetic-flux pump and electrical characteristics when operated as fully superconducting brushless generator with the capacity of less than 20 kW.
