It functions as an electromechanical device, converting electrical energy into rotational movement, which is stored as kinetic energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the. . A flywheel battery is a mechanical energy storage system that operates by spinning a mass, known as a rotor, at a very high speed. They use very large flywheels with a mass in the order of 100 tonnes. If we had enough of them, we could use them to stabilize power grids. At the core is the rotor – a cylindrical or disc-shaped mass that spins at high speed, often in excess of tens of thousands of. .
