Flywheel energy storage technology uses reversible bidirectional motors (electric motor/generator) to facilitate the conversion between electrical energy and the mechanical energy of a high-speed rotating flywheel.
A flywheel is a mechanical device that stores energy by spinning a rotor at very high speeds. The basic concept involves converting electrical energy into rotational energy, storing it, and then converting it back into electrical energy when needed.
We''ll learn how to build a small flywheel energy storage device which can store energy in a form of kinetic energy and afterwards convert it back to electrical power as needed.
When external electric energy is abundant, the motor is driven by an electric electronic device to rotate the flywheel and convert the electrical energy into storable mechanical energy.
The flywheel energy storage system is useful in converting mechanical energy to electric energy and back again with the help of fast-spinning flywheels. This system is composed of four key parts: a solid cylinder, bearings, a motor/generator and a vacuum sealed casing.
This project explores flywheel energy storage systems through the development of a prototype aimed at minimizing friction. I designed a motor with no mechanical bearings.

Compared 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 specific energy (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The energy efficiency (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 kWh to 13
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass.
