Therefore, the energy consumption per reciprocating stroke of a long stroke rodless cylinder pneumatic actuator is approximately the same at all frequencies. The horizontal and vertical W of a low profile rodless air cylinder electric actuator is significantly affected by f, with the line connecting the test points forming a downward-sloping curve. As f increases, W decreases. A pneumatic rodless actuators electric actuator also consumes energy in standby mode. The higher f, the lower the standby energy consumption, and the higher the efficiency of the rodless electric actuator.
