An assembly flywheel is an integral part of an automobile. A flywheel is a rotating disc that stores kinetic energy. These devices resist changes in their rotational speed and steady the rotation of the shaft. An assembly flywheel is used to produce very high power pulses.
The principle of the flywheel was discovered in the Neolithic spindle and the potter's wheel. This mechanical device is used for equalizing the speed of rotation, first described in the Kitab al-Filaha of the Andalusian engineer Ibn Bassal.
Recently, assembly flywheels have become major power storage devices used in vehicles. The flywheel energy storage accelerates a flywheel to a very high speed and conserves the energy as rotational energy. Once the flywheel is slowed down, the energy gets converted back. Electricity is often used to accelerate and decelerate the flywheel.
The advanced assembly flywheel systems have rotors made of high-strength carbon-composite filaments. The rotors are balanced by bearings inside a vacuum chamber, which reduces friction. It is linked to a combination electric motor.
