A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor.

Flywheel energy storage systems with mechanical transmissions allow regenerative braking and power augmentation during acceleration in automotive vehicles. The development of this technology is being driven by rising fuel costs and tightening emission legislation.

An easy-to-understand explanation of how flywheels can be used for energy storage, as regenerative brakes, and for smoothing the power to a machine. The physics of flywheels Things moving in a straight line have momentum (a kind of "power" of motion) and kinetic energy (energy of motion) because they have mass (how much

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

Electrical energy is generated by rotating the flywheel around its own shaft, to which the motor-generator is connected. The design arrangements of such systems depend mainly on the shape and type
