Flywheel

Flywheel

A flywheel is heavy metal wheel attached to a drive shaft, having most of its weight concentrated at the circumference. Main function of flywheel is to reduce speed fluctuation by storing extra energy during part load as kinetic energy and same is released during overloading. By slowly increasing the speed of a flywheel a small motor can store up energy which enables the motor to perform a function for which it is ordinarily too small.
