Air. Its all around us. Not only is it an essential component to life on earth, it also powers a lot of the tools we use today. A Pneumatic or air motor is a type of motor that does mechanical work by expanding compressed air. Pneumatic motors convert compressed air energy to mechanical work through linear or circular motion .
How does it work?
The concept of compressed air is simple: when atmospheric air is put under pressure, it creates potential energy that can be held inside a tank until its needed. When the pressurized air is released, the potential energy is converted into motion energy.
The basics of a air compression are simple. Air displacement. In order to compress air, the internal components of the compressor must move or change position to mechanically force the air through the chamber where it is compressed and stored until use.
Most common form that compressors use is positive displacement. Air is pulled into the chamber that opens and closes. Internal parts reduce the volume of the chamber and compress the air. The air is then pushed through the chamber and into a storage tank where it waits to be used.
