Flywheel energy system is a non-pollution energy storage system which uses high-speed rotationflywheel to store energy.As high temperature superconductor (HTS) bearings have very lowfriction and self-stability characteristic,they are applied to flywheel energy system increasingly.Inorder to investigate dynamic characteristics of HTS flywheel energy storage system (HFESS),weset up a HFESS and measured its radial-direction displacement and axial-direction displacementwhen it spun at different speeds.The rotational losses were measured after the PMR wasaccelerated.
