Electric Flywheel Basics. The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to (Equation 1) E = 1 2 I ω 2 [ J], where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm 2 ], and ω is the angular speed [rad/s].

Flywheel energy storage systems (FESSs) can be used in different applications, for example, electric utilities and transportation. With the development of new technologies in the field of composite materials and magnetic bearings, higher energy densities are allowed in the design of flywheels. The amount of stored energy in FESS

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.

These are: • In the absence of smooth continuous energy, to provide continuous smooth energy. For example, in reciprocating motors, flywheels are used because the torque produced by the motor is discontinuous. • A flywheel is used to store energy and then release it. In some cases, energy is released at a speed that the energy source cannot.

Generally, the flywheel rotor is composed of the shaft, hub and rim (Fig. 1). The rim is the main energy storage component. Since the flywheel stores kinetic energy, the energy capacity of a rotor has the relation with its rotating speed and material (eq.1). 1 2 2

Standby power loss can be minimized by means of a good bearing system, a low electromagnetic drag MG, and internal vacuum for low aerodynamic drag. Given the electric flywheel does not need a shaft

The capacity of a flywheel is the total energy stored – the rating is the rate at which energy may be extracted. A 1600kWhr capacity unit may have a rating of 25000kW for 200 seconds. A spinning flywheel therefore can be regarded as a heavy duty storage battery – the only limitation on rating being the capability of the power transfer means.
