Abstract

A high temperature superconductor bearing is disclosed which provide a strong levitation force and thus enable the construction of a horizontal-axle flywheel energy storage system. The bearing includes a magnet journal made of high temperature superconductor films, and a stator formed of a plurality of high temperature superconductors installed opposite to the high temperature superconductor magnet journal or the magnet journal for thereby off-setting the force such as the weight applied to the rotor using a magnetic pressure.
