Flywheel energy storage is a physical energy storage method. The principle is to use the inertia of a high-speed rotating flywheel to store energy. When charging, the flywheel motor rotates at an accelerated rate, converting the electrical energy into the mechanical kinetic energy of the flywheel and storing it; when.

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

Electric energy is supplied into flywheel energy storage systems (FESS) and stored as kinetic energy. Kinetic energy is defined as the "energy of motion," in this situation, the motion of a rotating mass known as a rotor, rotates in a near-frictionless environment. When utility power is lost or fluctuates, the inertia of the rotor permits it to continue spinning, converting the
