In energy storage, the principle of the flywheel can be used. Flywheels store energy in the form of the angular momentum of a spinning mass, called a rotor. The work done to spin the mass is stored in the form of kinetic energy. Video 1 is a simple video that illustrates the concept of flywheel electrical energy storage.

Low-speed flywheels, with typical operating speeds up to 6000 rev/min, are constructed with steel rotors and conventional bearings.
