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. The energy is converted back by slowing down the flywheel. Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed.

The amount of energy stored, E, is proportional to the mass of the flywheel and to the square of its angular velocity is calculated by means of the equation (1) E = 1 2 I ω 2 where I is the moment of inertia of the flywheel and ω is the angular velocity. The maximum stored energy is ultimately limited by the tensile strength of the flywheel material.
Abstract. The flywheel energy storage system (FESS) is a closely coupled electric-magnetic-mechanical multiphysics system.

Flywheel Energy Storage is a form of kinetic energy storage that uses rotating discs to store and release rotational energy. While the technology has been around for decades as a form of Uninterrupted Power Supply (UPS) to provide power when main sources fail, it has more recently begun to be refined and developed.
Flywheel Energy Storage Systems convert electricity into rotational kinetic energy stored in a spinning mass. The flywheel is enclosed in a cylinder and contains a large rotor inside a vacuum to reduce drag. Electricity drives a motor that accelerates the rotor to very high speeds (up to 60,000 rpm). To discharge the stored energy, the motor ...

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…

Flywheel, heavy wheel attached to a rotating shaft so as to smooth out delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use. To oppose speed fluctuations effectively,
