Research Abstract

Generally, it has been said that homopolar machines cannot be applied for practical use because their output voltages are too small. In order to improve this characteristics, we introduced a high magnetic field of a superconducting magnet. And, we also introduced a multi-disk-type armature, which has many rotating armature disks connected in series electrically. An experimental machine with two armature disks and a superconducting field. The experimental results shows ;
(1)the magnetic field is not shielded by the armature rotating disks,
(2)the output voltage becomes the sum of each armature disk voltage,
Apart from the experimental study, we carried out a conceptual design of a large scale superconducting homopolar machine with a rating of 500kV,500MW.From the design study, it becomes clear that the AC/DC converter using this homopolar machine can generate DC power directly with the efficiency of 99.7%, which is much higher than the usual stationary type converters.
The technological problems left to be solved are listed below ;
(1)the development of high performance current collecting brush system,
(2)the increasing of the diameter of the rotating disk is very effective to increase the output voltage,
(3)the establishment of shielding technology of stray magnetic field.
