This motor/generator can either accelerate the rotor to store energy or decelerate the rotor to convert the stored energy into electrical power. 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. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. The energy is stored as kinetic energy and can be retrieved by slowing down the flywheel. . This can be seen as a manual electricity generator using a flywheel wherein the flywheel needs to be pushed occasionally for sustaining a consistent rotation over the attached motor. This paper gives a review of the recent developments in FESS technologies. Due to the highly interdisciplinary nature of FESSs, we survey different design. . The laws of physics (explained briefly in the box below—but you can skip them if you're not interested or you know about them already) tell us that large diameter and heavy wheels store more energy than smaller and lighter wheels, while flywheels that spin faster store much more energy than ones. .
