Air Motor Performance

Advertisements

Air motors differ in many ways from other power sources. These unique operating characteristics must be considered when selecting an air motor for a particular job. It is easy to change the horsepower and speed of an air motor by throttling the air inlet.

Therefore, the best rule of thumb for selecting an air motor is to choose one that will provide the horsepower and torque needed using only two-thirds (2/3) of the line pressure available. The full airline pressure will then be available for overloads and starting.

Torque vs. Speed

Air Consumption vs. Speed

Air consumption increases as speed and air pressure are increased.
