1. Small size can produce high power.
2. High adaptability, the temperature rise is small, and the speed can be changed with the load until the overload stops without causing any damage to the air motor, so a lower safety factor can be considered when choosing.
3. Emergency start, emergency stop, especially suitable for frequent start-up occasions, and the reversal is very easy.
4. Simple stepless speed regulation, from zero to maximum, flexible operation.
5. The starting torque is large, and it can be started with load.
6. The structure is simple, and the service life of the air motor is particularly long.
7. It is not affected by the external environment, even in the harsh environment such as water, dusty, humid and dirty, because the internal pressure is greater than the external pressure when the air motor is running.
8. Safe, explosion-proof, air motor does not produce sparks, overheating, explosion, short circuit (electricity) and other risk factors, especially suitable for the environment with flammable and explosive substances or high temperature, such as the stirring of solvents, paints, chemicals, etc.
These are the main advantages of air motors over electric motors and the reasons why they are adopted in several industrial sectors. The disadvantages of air motors are: low output power, large air consumption, low efficiency, high noise, and easy to vibrate.
