What are the components of flywheel energy storage system
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.
A typical system consists of a flywheel supported byconnected to a . The flywheel and sometimes motor–generator may be enclosed in ato reduce friction and.
TransportationAutomotiveIn the 1950s, flywheel-powered buses, known as , were used in() and() and there is ongoing research to make flywheel systems that.

GeneralCompared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance;full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use),high.
Flywheels are not as adversely affected by temperature changes, can operate at a much wider temperature range, and are not subject to many of the common failures of chemical .They are also less potentially damaging to the environment, being.

This article comprehensively reviews the key components of FESSs, including flywheel rotors, motor types, bearing support technologies, and power electronic converter technologies.
The main components of a flywheel are a high-speed permanent magnet motor/generator, fully active magnetic bearings, and rotor assembly construction (Figure 1). 1.
So, in this study, the FESS configuration, including the flywheel (rotor), electrical machine, power electronics converter, control system, and bearing are reviewed, individually and comprehensively.
