Electrohydraulic compact drives (ECDs) are a special form of pump-controlled systems. A feature of these drives is the integration of all components in one assembly. So the ECDs only have one electric and one mechanical interface. In addition to the advantages of hydraulic drives, such as high force density and simple overload protection, ECDs have further advantages known from electromechanical drives (EMDs), mainly simple installation as well as simple commissioning and low maintenance effects.
