Summary

The authors developed a new type of flywheel energy storage system that has a horizontal axle with high T(c) superconductor bearings using the Y123 single-domained crystals. The dynamic properties, stiffness and damping, of the high T(c) superconductor radial bearings applied in the flywheel energy storage system were experimentally estimated using the imbalance excitation method. The imbalance excitation method applied to this rotor-bearing system identified the direct stiffness and damping of the high temperature superconductor bearings to be 2.8-3.3 x 100000 N/m and 175-204 Ns/m, respectively.
