We all know that the speed and torque can also be adjusted by installing a pressure reducing valve at the upstream air supply. When low-pressure air is continuously supplied to the motor and the motor decelerates, a very low torque is generated on the output shaft. Today, let the editor summarize the 4 major methods for controlling air motors:

1. The compressed air supply must have large enough pipes and valves to ensure the maximum torque of the motor. At any time, the motor needs a supply pressure of 6bar. When the pressure is reduced to 5bar, the power reduces the throttle of the motor.

2. The air to be supplied to the motor must be filtered and decompressed. The directional control valve needs to supply air to the motor and rotate the motor when needed. Such valves can be pneumatically controlled, electronically controlled, or mechanically controlled.

3. If the motor is not used for direction rotation, the flow regulating valve can be installed in the air supply line to adjust the speed of the motor. If the motor is used for reverse rotation, the flow control valve with internal one-way function needs to adjust the rotation in each direction. The internal one-way valve allows air to be discharged from the exhaust port of the residual air of the motor to the exhaust port of the control valve, and then discharged.

4. When the motor is used in applications that do not require bidirectional rotation, it is sufficient to use a 2/2 or 3/2 valve to control it. For motors that can rotate in the opposite direction, a 5/3 or two 3/2 valves are required to ensure that the motor has compressed air supply and residual air exhaust.

The above are the four methods for controlling the air motor summarized by the editor. The most common way to reduce the speed of the air motor is to install a flow control valve at the air inlet. When the motor uses the air inlet, it can also be used for the exhaust port. Flow regulation is also used on the main exhaust port so that the speed can be controlled in both directions.
