When the electric machine is acting as a motor, it charges the flywheel by accelerating it and drawing electrical energy from the source, storing the energy. When this energy is required, the same machine then acts as a generator, extracting it, thereby slowing down the flywheel.

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
