READ MOREShare 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.
READ MOREIn flywheel energy storage systems, the flywheel, similarly to high-speed rotors, is designed to be precision-balanced. They are designed such that, after balancing, the flywheel''s mass centre is usually within 1.3 × 10 −6 m from the centre of rotation. The radial magnetic bearings determine the centre of rotation.
