We have tested a 200 mm compact HTS magnetic bearing for flywheel application up to a maximal load of 1000 kg axially and 470 kg radially at 72 K. The maximal axial stiffness is 4.5 kN/mm and the radial 1.8 kN/mm. The influence of temperature and hysteretic depinning on the bearing force is investigated.
Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel''s secondary functionality apart from energy storage.

Share this post. Flywheel energy storage systems (FESS) are a great way to store and use energy. They work by spinning a wheel really fast to store energy, and then slowing it down to release that energy when needed. FESS are perfect for keeping the power grid steady, providing backup power and supporting renewable energy sources.
