How hydraulic motion-control measures up: For positioning large loads, electrohydraulics can be a better choice than electromechanical motion systems

摘要

Fluid-power systems often take a back seat to traditional electromechanical motion control. But designers who understand both technologies can take advantage of the best features of each, and in the process build higher-quality machines with lower life-cycle costs. Particularly for applications that require precise control of large forces and smooth motion, fluid power can deliver significant benefits. However, that means selecting the right hydraulic-system elements and tuning the motion controller for optimal performance.
