Flywheel is generally applied in energy storage systems to keep up with the energy in the system as rotational energy. Providing energy at higher rates than the limit of the energy source. This is done by getting energy in a flywheel after some time. Then, at that point, releasing it rapidly at rates that surpass the energy source''s capabilities.
Energy storage flywheel systems are mechanical devices that typically utilize an electrical machine (motor/generator unit) to convert electrical energy in mechanical energy and vice versa. Energy is stored in a fast-rotating mass known as the flywheel rotor. The rotor is subject to high centripetal forces requiring careful design, analysis, and fabrication to

flywheel, heavy wheel attached to a rotating shaft so as to smooth out delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use. To oppose speed fluctuations effectively, a flywheel is given a high rotational inertia

Energy Release: When the grid requires additional power (e.g., during peak demand or when renewable energy supply is low), the Flywheel Energy Storage System releases the stored energy. The spinning rotor transfers its kinetic energy back to the generator, which converts it into electrical energy and feeds it back to the grid.
A flywheel is essentially a mechanical battery consisting of a mass rotating around an axis. It stores energy in the form of kinetic energy and works by accelerating a rotor to very high speeds and maintaining the energy in the system as rotational energy. Flywheel energy storage is a promising technology for replacing conventional lead acid
When energy is required, the motor functions as a generator, because the flywheel transfers rotational energy to it. This is converted back into electrical energy, thus completing the cycle. As the flywheel spins faster, it experiences greater force and thus stores more energy. Flywheels are thus showing immense promise in the field of energy
