Flywheel Energy Storage System | PDF | Electric Motor
Flywheel energy storage systems store energy kinetically by accelerating a rotor to high speeds using electricity from the grid or other source. The energy is then returned to the grid by decelerating the rotor using the motor as a generator. Key components include a flywheel, permanent magnet motor/generator, power electronics for charging and

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
