Eight selection criteria for actuation components

摘要

When deciding between fluid-driven and electromechanical linear actuators, close consideration of long-term benefits to the intended end user can help original equipment manufacturer (OEM) system designers maximize both product value and return on investment (ROI).Fluid-driven actuators translate electric energy motion through a column of air, gas, oil or other media. While the motion they provide is simpler than with other type actuators, the infrastructure required to support them is not. Hydraulic actuators require an external system of pumps and valves; Pneumatic actuators require complex air delivery systems. For both, stroke length is defined by a mechanical hard stop.
