A pneumatic motor (air motor) or compressed air engine is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion.

In this video I’m making a 5 vane rotor air (pneumatic) motor. This type of motor is used in a variety of air tools seen every day, nothing uncommon. While this may not be very exciting, I found that this is actually a positive displacement pump.

That means, it can be a perfectly working miniature supercharger. This type of supercharging was applied decades ago in actual engines and worked very reliably.

In my case though I’ll need to change the materials of the vanes and the housing for better sealing and reliability.
Pneumatic motors have found widespread success in the hand-held tool industry, but are also used stationary in a wide range of industrial applications.
