Flywheel is usually applied in energy storage systems to maintain the energy in the system as rotational energy. Providing energy at rates higher than the capacity of the energy source. This is done by getting energy in a flywheel over time. Then releasing it quickly at rates that exceed the energy source''s capabilities.

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational 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 system correspondingly results in an increase in the speed of th…
