Although the structure and working principle of each type of air motor are different, most of them have the following characteristics:

1. stainless steel long shaft motor products can be stepless speed regulation. As long as the opening of the intake valve or exhaust valve is controlled, that is, the flow of compressed air is controlled, the output power and speed of the motor can be adjusted. The purpose of adjusting speed and power can be achieved.

2. can rotate forward or reverse. Most air motors can realize the positive and reverse rotation of the output shaft of the gas motor and can change the direction of the motor by simply changing the direction of the motor inlet and exhaust by using the control valve. In the positive and negative conversion, the impact is very small. One of the main advantages of the reversing operation of the air motor is that it has the ability to rise to full speed almost instantaneously. The blade type air motor can rise to full speed in one and a half revolutions; The piston type gas motor can rise to full speed in less than one second. The positive and negative direction can be realized by changing the direction of intake by using the control valve. The time to realize the positive and negative reversal is short, the speed is fast, the impact is small, and the load is not unloaded.

3. safe working, free from vibration, high temperature, electromagnetic and radiation, and suitable for harsh working environment. It can work normally under the unfavorable conditions of inflammable, explosive, high temperature, vibration, humidity and dust.

4. it has overload protection function and will not fail due to overload. When overload occurs, the motor only reduces or stops the speed. When overload is relieved, it can be operated again and can not cause damage of parts and other faults. It can run continuously with full load for a long time, and the temperature rise is small.

5. It has high starting torque and can be started directly with load. It starts and stops quickly. It can be started with load. Start and stop quickly.

6. Wide range of power and speed. The power is as small as several hundred watts and as large as tens of thousands of watts; The speed can be from zero to ten thousand revolutions per minute.

7. Easy to operate, easy to maintain and repair. The pneumatic motor has the advantages of simple structure, small volume, light weight, high horsepower, easy operation and convenient maintenance. 8. Using air as the medium, there is no difficulty in supply, the used air does not need to be treated, put into the atmosphere without pollution, compressed air can be centralized supply, long-distance transmission

Because of the above characteristics, the air motor can work in humid, high temperature, high dust and other harsh environment. In addition to being used as power in rock drilling, drilling, loading and other equipment in mining machinery, it is also widely used in shipbuilding, metallurgy, chemical industry, papermaking and other industries.
