Air Motor Overview


Working principle:

The air motor (pneumatic motor) does work by converting compressed air to mechanical work through either linear or rotary motion. The rotary motion is generated either by a vane type air motor or a piston air motor. Our air motors are rotary vane type, i.e. a slotted rotor is mounted on the drive shaft whereby each of the four slots has a freely sliding rectangular vane. Rotational speed is between 500-6,000 RPM for the direct drive multi vane air motors, depending on the model and motor size. The larger air motors (4HP/3kW) can be additionally equipped with a gear reducer which can bring the speed down to 15 RPM


Air motors are widely used in the hand-held tool industry and for agitators, mixers and stirrers in hazardous environments and more volatile atmospheres. Compared to electric motors, air motors do not require a speed controller (only a simple air regulator), have cool running characteristics, generate less heat and can be used in high temperature environments.
