Wikipedia Meaning and Definition on 'Flywheels'


A flywheel is a mechanical device with a significant moment of inertia used as a storage device for rotational energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based (reciprocating) engine, or when an intermittent load, such as a piston pump, is placed on it.

Flywheels can be used to produce very high power pulses for experiments, where drawing the power from the public network would produce unacceptable spikes. A small motor can accelerate the flywheel between the pulses.

Recently, flywheels have become the subject of extensive research as power storage devices for uses in vehicles and power plants.

The principle of the flywheel is found in the Neolithic spindle and the potter's wheel.
