In this study, a high-temperature bulk superconductor (HTS bulk) was combined with superconducting coils to increase the load capacity of the bearing. The flywheel energy storage system has a high energy density, and offers excellent performance in the areas of start/stop operation. . The low coefficient of friction of high-temperature superconductor bearings used in flywheel-based energy storage systems decides the energy loss factor. Two flywheels having 400mm in diameter were accelerated up to 30 000 min-1with no contact bearings, a. . In this paper, a new superconducting flywheel energy storage system is proposed, whose concept is different from other systems.
