Air motor or Air gear motor

Motor or dynamo is a rotating drive. The most often used type, uses electricity as its main power source and usually referred to as electromotor. In some of its applications, electromotor could not even be used due to its special application. This special application cannot be applied under one of some situations, such as; when generated power and RPM are difficult to set, electricity usage is prohibited, and/or the ambient temperature is too extreme (above 60 C).

Air motor or a pneumatic motor, is a motor that moves something by using airflow/wind generated by spinning the motor.

Because of that, a motor that is most suitable to be installed without consuming electricity is the air motor or pneumatic motor. Just like the electromotor, the variable used to determine which types of air motor suits you best are the power (KW or HP) and RPM. And also there are two types of mounting, the foot mounting or flange mounting.

In an air motor, to make the motor spins, it does not use electricity; instead, it uses pressurized air or compressed air to make the motor spin. In industry, the use of air motor is applied in machinery, rooms, or area that restricted usage of electricity due to a certain condition.

Air motor in its application, often coupled with gears is called Air gear motor and the model is determined based on its ratio. The most important thing for an air motor to be working is a constant, sustained compressed air supply. The amount of compressed air that is consumed depends on the size of the model used (HP or KW). Aside from gear, there are also other types of, air motor that is commonly used. Its motor works just equally simple as the air gear motor, those two types are piston  air motor and vane air motor, and also there is a gear type.

Determining the model and the type of air motor or air gear motor is not really different from determining the type and model of electromotor or electric gear motor, which is determined by its power in KW or HP measurement unit. Then the type of mounting of air motor used could be either foot mounting or flange mounting, depends on its application. Changing the ratio on Pneumatic Gearmotor to the desired amount is using the same manner.

Regarding its price, the air motor is relatively more expensive compared to the electromotor. But air motor is really valued for its superior characteristics, explosion-proof, which makes it safe from explosive and fire hazard. This makes air motor is most often used as a mixer in a solvent-based-paint industry.

Adjusting the amount of power and the rotation speed of a pneumatic motor can be done easily. To perform the adjustment, for opening or closing the valve and amount of power/torque generated by pneumatic motor can be done through the regulator setting, for rotation speed (Revolution Per Minute) can be done through a speed control setting.

Air motor, in terms of maintenance, is quite simple, even can be considered as maintenance-free, provided the quality of the air used meets the standard or pass the air treatment.

The USA-made or Europe-made pneumatic motor or air gear motor is surely more expensive. Some brands that are commonly seen in the market are; PSI (Pneumatic system Inc), Gast, Huco Dynatork, Globe, Atlas Copco, Ingersoll Rand, Mannesmann Demag, Deprag Inc.

But if you are in a tight budget, air motor products made in China, Taiwan, Korea, and a number of Japan-made products, might be the one for you. These products are relatively cheaper but only by a slight margin. Aside from their price, they also provide a wide range of variants, like Tonson Air Motor, that has wide application variants.

In general, the standard Air motor in the market does not have many variants in terms of power. The power range are; 0.45 HP, 0.93 HP, 1.7 HP, 4 HP, 5.25 HP, 9.5 HP and 2.5 HP. And ratio for Air Gear Motor are: 15:1, 10:1, 20:1, 40:1, 60:1,
