An air motor is also called a pneumatic motor, which refers to a device that converts the pressure energy of compressed air into mechanical energy that rotates. Generally used as a source of rotating power for more complex devices or machines.

Compared with electric motors that serve the same purpose, air motors are characterized by a light outer casing and convenient transportation; and because the working medium is air, there is no need to worry about causing a fire; when the air motor is overloaded, it can automatically stop and meet the supply pressure Keep your balance. Due to the above characteristics, pneumatic motors are widely used in mining machinery, flammable and explosive liquids, and pneumatic tools.

Comparison of advantages and disadvantages of air motor and hydraulic motor

Air motor compared to hydraulic motor:

advantage
(1) Work safety, explosion-proof performance, and not affected by high temperature and vibration;
(2) It can work at full load for a long time, and the temperature rise is small;
(3) The power range and speed range are both wide, the power is as small as several hundred watts and as large as several tens of thousands of watts;
(4) It has a high starting torque. It can start with load;
(5) Simple structure, convenient operation, easy maintenance and low cost.

Disadvantage
(1) Poor speed stability;
(2) small output power, low efficiency and large air consumption;
(3) Noise is large and vibration is easy to occur.
