Active power Inc. [78] has developed a series of fly-wheels capable of 2.8 kWh and 675 kW for UPS applications. The flywheel weighs 4976 kg and operates at 7700 RPM. Calnetix/Vycons''s VDC [79] is another example of FESS designed for UPS applications. The VDC''s max power and max energies are 450 kW and 1.7 kWh.
Flywheel | Energy Storage, Kinetic Energy & Momentum | Britannica
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, a flywheel is given a high rotational inertia
Flywheel Energy Storage System
Flywheel energy storage system (FESS) is an electromechanical system that stores energy in the form of kinetic energy. A mass coupled with electric machine rotates on two magnetic bearings to decrease friction at high speed. The flywheel and electric machine are placed in a vacuum to reduce wind friction.

The role of flywheel energy storage in decarbonised electrical power systems
A flywheel is a very simple device, storing energy in rotational momentum which can be operated as an electrical storage by incorporating a direct drive motor-generator (M/G) as shown in Figure 1. The electrical power to and from the M/G is transferred to the grid via inverter power electronics in a similar way to a battery or any other non-synchronous
Flywheel Energy Storage: Why It Is So Important?
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. As a result of the energy conservation principle, the flywheel''s rotational speed decreases when energy is removed from the system and increases when energy is added.
