The blade type pneumatic motor has smaller size, lighter weight and lower cost compared with a similar power piston motor. Simple designs and structures enable them to operate at any installation angle in most cases. The blade motor has a wide range of speed, torque and power, which is the most commonly used form of pneumatic motor.

The radial piston pneumatic motor operates at a lower speed than that of a vane type motor. It has excellent performance in starting and speed control. It is especially good at running in low speed and heavy load conditions. The standard operation position is horizontal.

The rotational speed, torque, and power rating of a unidirectional rotating pneumatic motor are slightly higher than that of the same series of reversable pneumatic motors

When choosing a pneumatic motor, remember that the list of technical specifications shows only a set of performance figures at a specific pressure - 90psig. The calibration performance of the pneumatic motor is the working performance under this pressure. The same motor can achieve many different speeds by adjusting pressure, gas supply, or exhaust. Torque and power. When they operate under the pressure of less than 40psig, their performance may be unstable. A good rule to follow is to determine the size of the pneumatic motor with a minimum of about 70% of the air pressure that can be reached. This allows extra power to be used for aerodynamic and possible overloading.

Maximum power: the maximum output power of a pneumatic motor without speed regulation is about 50% when the idle speed is about 50%, while the speed motor achieves its peak power when the idle speed is about 80%.

Working speed: when the pneumatic motor is selected, the working speed should be considered, not the unloaded speed.

The unregulated motor should not run empty. The performance curve indicates the maximum rotation speed of the motor. The appearance of the imprint speed on the nameplate is only for the purpose of marking.

Required torque: working torque is as important as the rotating speed of the pneumatic motor. The combination of two factors, speed and torque, determines the power of the motor required. When the old horse, must pay attention to the difference between the stalling torque and rated torque.
