Flywheels: How do they work and what do they do? By Chris Woodford . Last updated: January 10, 2012. S top... start... stop... start—it's no way to drive! Every time you slow down or stop a vehicle or machine, you waste the momentum it's built up beforehand, turning its kinetic energy (energy of movement) into heat energy in the brakes . Wouldn't it be better if you could somehow store that energy when you stopped and get it back again the next time you started up? That's one of the jobs that a flywheel can do for you.

Flywheel electricity generator. Abstract: A flywheel (magnet rotors or stators) assembly to create electricity, by attaching motor to provide kinetic energy to magnet rotors or stators, so magnet rotors or stators can run on principal of flywheel to create electricity by magnet rotors rotating like flywheel on two sides of stator, and stator rotating like flywheel in-between magnet rotors.

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 system correspondingly results in an increase in the speed of the flywheel. Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed.[1] Since FES can be used to absorb or release electrical energy such devices may sometimes be incorrectly and confusingly described as either mechanical or inertia batteries [2][3] Main components[edit] The main components of a typical flywheel. A typical system consists of a rotor suspended by bearings inside a vacuum chamber to reduce friction, connected to a combination electric motor and electric generator.

太阳能、风能、潮夕能、海浪能，都存在储存问题，目前主要靠化学电池，但受到化学蓄电池寿命及效率的制约，至今尚不能广泛应用。 VYCON - Flywheel Technology. Flywheels have been used since the Bronze Age as a way to store kinetic energy.
Today, with new high speed motor technology, VYCON has developed highly efficient flywheel systems which provide consistent, dependable energy for a variety of important applications. VYCON's flywheel-based energy storage systems hold kinetic energy in a spinning mass, and convert this energy to electric power through the use of a high speed electric motor/generator. Advanced flywheel systems from VYCON originated from its parent company Calnetix, the leader in high speed permanent magnet motors and generators, magnetic bearings, power electronics and system integration. Main components of the VYCON flywheel -- a high-speed permanent magnet motor/generator, fully active magnetic bearings, and the rotor assembly construction -- constitute a unique synthesis of proprietary technologies: High Speed Permanent Magnet Motor/Generator.
