Difference between Flywheel and Governors

Comparisons between Flywheel and Governors are made in the following aspects: purpose, principle, application, and mechanism.

S.no	Flywheel	Governors
1	Flywheel is provided on the engine and fabricating machines, viz., rolling mills, punching machines, shear machines, presses, etc.	The governor is provided with information on prime movers such as engines and turbines.
2	Its function is to store available mechanical energy when it is more than the load required and to the part when the available energy is less than that required by the load.	Its function regulates the supply of driving fluid producing energy; according to the load requirements, almost a constant speed is maintained at different loads.
3	In engines, it takes care of speed fluctuations during the thermodynamic cycle.	It handles speed fluctuation due to load variation over various working engines and turbines.
4	It works continuously from cycle to cycle.	It works intermittently, i.e., only when there is a change in the load.
5	Fabrication machines are very economical, as they reduce capital investment in prime movers and their running expenses.	However, the governor would have consumed unnecessarily more driving fluid, so it economizes its consumption.
