Since the rotor in rodless actuators is installed eccentrically, multiple sickle-shaped working chambers are formed. The two blades have different extension lengths, so that the effective area of compact rodless cylinder gas pressure is unequal, resulting in a torque difference, causing the rotor to rotate counterclockwise. When the central rotor rotates, the volume of the studio changes, and a pressure difference is generated on the blades of adjacent studios. This pressure difference is used to drive the rotor double acting rodless cylinder to rotate. The seal between the blades electric rodless cylinder and the inner surface of the shell is ensured by its own centrifugal force during operation, and is achieved by introducing compressed air at its bottom or using a spring during the startup phase. The gas after work is discharged from the output port guided rodless cylinder. If the compressed air input direction is changed, the direction of the rotor can be changed.
