What is a flywheel power system?
Flywheel power systems, also known as flywheel energy storage (FES) systems, are power storage devices that store kinetic energy in a rotating flywheel. The flywheel rotors are coupled with an integral motor-generator that is contained in the housing. The motor-generator is used to store and then harness energy from the rotating flywheel.
How does a flywheel energy storage system work?
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. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
