Air Motor Principle
Air motor, also known as air motor, refers to a device that converts the pressure energy of compressed air into rotating mechanical energy. Typically used as a source of rotational power for more complex devices or machines. Air motors are classified by structure into: vane air motors, piston air motors, compact vane air motors, and compact piston air motors.
principle
Pneumatic actuators that convert the pressure energy of compressed gas into mechanical energy and generate rotary motion in pneumatic transmission. The commonly used pneumatic motor is a positive displacement air motor, which uses the volume change of the working chamber to do work, and is divided into vane type, piston type and gear type. [1]
An air motor is a device that converts the pressure energy of compressed air into rotational mechanical energy. Its function is equivalent to an electric motor or a hydraulic motor, that is, the output torque is used to drive the mechanism for rotational motion.
The main differences between air motors and electric motors (or motors) are:
1. Small size can produce high power.
2. High adaptability, small temperature rise, the speed can be changed with the load, and will not cause any damage to the air motor until the overload stops, so a lower safety factor can be considered when choosing.
3. Emergency start and emergency stop, especially suitable for occasions with frequent start, and the direction change is very easy.
4. Simple stepless speed regulation, from zero to maximum, flexible operation.
5. The starting torque is large, and it can start with load.
6. The structure is simple, and the service life of the air motor is particularly long.
7. Not affected by the external environment, even in harsh environments such as water, dusty, humid, dirty, etc., because the internal pressure of the air motor is larger than the external pressure when it is running.
8. Safe, explosion-proof, the air motor does not produce sparks, overheating, explosion, short circuit (electricity) and other dangerous factors, especially suitable for environments with flammable and explosive substances or high temperature, such as stirring of solvents, paints, chemicals, etc.
