The work deals about the design of a pneumatic rotating servomotor intended for low speed, high torque operation. The servosystem is based on a pneumatic orbital motor working in the 0 – 80 rpm range with a maximum torque of 28 Nm, and hence it can be applied in heavy duty application. The paper analyses the kinematic layout of the motor, shows the results of characterisation tests and finally it discusses the layout and the components to implement closed loop velocity control. The effectiveness of control layout based on the use of pressure proportional and flow proportional valves is compared by experimental tests. The results show the capabilityof the servosystem to keep the set velocity and to react to external disturbance.

Abstract
The work deals about the design of a pneumatic rotating servomotor intended for low speed, high torque operation. The servosystem is based on a pneumatic orbital motor working in the 0 – 80 rpm range with a maximum torque of 28 Nm, and hence it can be applied in heavy duty application. The paper analyses the kinematic layout of the motor, shows the results of characterisation tests and finally it discusses the layout and the components to implement closed loop velocity control. The effectiveness of control layout based on the use of pressure proportional and flow proportional valves is compared by experimental tests. The results show the capabilityof the servosystem to keep the set velocity and to react to external disturbance.File | Dimensione | Formato | |
