Industrial Electrohydrostatic Actuation Systems

Moog Electrohydrostatic Actuators are a component within a complete Electrohydrostatic Actuation System (EAS). Available as modular, compact, or fully customized systems, machine builders use this technology to generate linear motion with the benefits of the power of electrohydraulic (EH) and the efficiency of electromechanical (EM) actuation.

A complete system is comprised of an electrohydrostatic pump unit, a variable speed servo motor and a fixed or variable displacement pump along with a manifold and cylinder. The energy input into the power train is provided by a servo drive. These building blocks make up Moog‘s Modular EAS, a dynamic and attractive solution for the industrial machine manufacturing market.
