What are Flywheels? Flywheels Overview

One of the most integral parts of a car’s engine is flywheels that store kinetic energy. They resist any change in their speed of rotation. It is done by steadying the shaft when pressure is applied to them. Among the many purposes of flywheels, one is to use them for creating high power pulses for carrying out some experiments. The focus on flywheels has thickened due to their proven ability to store energy. Now they are being explored as power storage devices for automobiles.

Satellite pointing is one of the most exciting uses of the flywheels according to one of the articles on Wikipedia. It is known as momentum wheel, which is used to direct the satellites in the required directions without using any kind of thrusters. Thus, it proves that flywheels have endless uses. With some imagination and out of box thinking it is not difficult to use flywheels as power storage devices in many fields. The collaboration of a proven old technology with a new and upcoming technology is always an exciting venture.

The vertical axis flywheels are used in cars so that the kinetic energy generated by the flywheels can be put to provide lateral momentum to the vehicle while it is moving on a hilly terrain.

The flywheels are as old as Roman Empire, steam engines, potters wheels and many other known inventions. But the irony is that it has never got the attention of the public as it deserved.

The modern vehicle engines use a aluminum flywheel. Aluminum flywheels are lighter in weight than the steel ones thus; they help in producing more horsepower and enhance the engine life. They cause less stress on bearings and crankshaft of the engine. A set of flywheels can be used continuously for years without any maintenance and replacement. After having read this article, you ought to find out the instruments that you use in your daily life that have flywheels.
