A Flywheel System

摘要

The present disclosure relates to a flywheel system. The flywheel system comprises a rotation axis and a flywheel rotor connected to the rotation axis. Further, the system comprises a drive and/or a power generator connected to the flywheel rotor. According to the invention, the flywheel rotor has an outer radius in radial direction of at least 0.85 meter, preferably at least meter, and more preferably at least 1.30 meter. The invention further relates to flywheel rotors having a thickness in axial direction of at least 0.30 meter, preferably at least 0.45 meter, and more preferably at least 0.60 meter. Finally, the invention also relates to a flywheel system of which the rotor has a weight of at least 2.5 tons, preferably at least 4 tons and more preferably at least 5 tons.
