Flywheel energy storage systems consist of a rotor (flywheel), a motor/generator, magnetic bearings, and a containment system. The rotor, typically made from advanced materials like carbon fiber, is enclosed in a vacuum chamber to minimize air friction. 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 energy storage system is a mechanical device used to store energy through rotational motion. Therefore, it can store energy at high efficiency over a long duration.

What is a flywheel power system?
Flywheel power systems, also known as flywheel energy storage (FES) systems, are power storage devices that store kinetic energy in a rotating flywheel. The flywheel rotors are coupled with an integral motor-generator that is contained in the housing. The motor-generator is used to store and then harness energy from the rotating flywheel.
