Title:
HIGH-TEMPERATURE SUPERCONDUCTIVE ROTARY MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/101486
Kind Code:
A1
Abstract:
The present invention relates to a high-temperature superconductive rotary machine with an improved cooling structure of a field magnet and/or an armature coil. The high-temperature superconductive rotary machine according to the present invention is a rotating field magnet-type superconductive rotary machine in which a field coil inner cylinder, which communicates with a heat exchanger provided in a liquified hydrogen tank for supplying hydrogen gas to a fuel cell and accommodates therein an inert refrigerant having a higher boiling point than liquid hydrogen, is provided inside a field coil made of a high-temperature superconducting wire and an armature coil made of a high-temperature superconducting wire is accommodated in an armature coil cooling tank together with an inert refrigerant, and then, by circulating the inert refrigerant, both the field coil and the armature coil can be cooled, thus enabling superconducting thereof without the need to provide a separate cooler for each coil even though the field coil and the armature coil are made of high-temperature superconducting wires. Thus, according to the present invention, the configuration of the high-temperature superconductive rotary machine is simplified with the advantages of reducing the volume and weight thereof while improving the efficiency of the machine.
