Introducing air motorsThe air motor is one of the toughest and most versatile power units available to the design engineer. The features and characteristics of the Atlas Copco air motor make it the natural choice of power for industrial applications, both in the present and future.
Compact and lightweightFirst, the compact nature of an air motor must be included as a main benefit. An air motor weighs about 1/4 as much as an electric motor with the same output. On top of that, air motors typically occupy only 1/6 of the space. Air motors produce far more power in relation to their size and weight than most other types of motors. Additional benefits:
- Torque increases with load. The output of an air motor is relatively constant within a wide speed range. When an increase in load lowers the speed, the torque increases.
- Adjust power output step-lessly. An air motor’s torque and output can be adjusted step-lessly by varying the working pressure. Along with that, speed can be adjusted step-lessly throughout its entire range by varying the airflow.
- Durability. Air motors are undamaged by overloads. Additionally, they can be stalled indefinitely without overheating or sustaining any other type of damage. They can also be repeatedly started and stopped without limits or negative consequences.
- Ideal in hazardous and hostile environments. Air motors do not generate sparks, so they are ideal for areas with serious explosion and/or fire hazards. Moreover, their rugged design and construction make them ideally suited for salt-laden and other corrosive atmospheres.
- Easily reversed. Air motors work efficiently in either direction. They are easily reversed using a directional valve.
- Simple installation. Air motors are able to operate in any position. The motors and required air lines are easy to install.
- Rugged. Air motors are virtually unaffected by knocks and blows, heat, vibration and corrosion. Their performance in hostile environments cannot be matched by the other types of motors available.
