Summary

The project conducted by NEDO for developing a high-temperature superconducting flywheel energy storage system is introduced; the two test results of fundamental studies are described. One is the measurement of levitation force and rotation loss of superconducting magnetic bearings composed of oxide superconducting bulks and permanent magnet composite. Two types of superconducting magnetic bearings, axial and radial types, were fabricated and tested. The other test was the fabrication and testing of two functional models. A small-sized superconducting flywheel model of the 0.5 kWh class was fabricated and tested. A medium-sized rotating functional model of the 10 kWh class was fabricated as well.
