Moog Modular Electrohydrostatic Actuation System

The Moog Modular Electrohydrostatic Actuation System (Modular EAS) features standardised modules with a wide number of customisation options available. This process allows for extensive application potential by meeting the specific application requirements. The system’s smallest scope of delivery consists of a basic manifold and an electrohydrostatic pump unit (EPU), which Moog delivers as an assembled and tested unit.

To expand the system, the basic module can be combined with various options or adapted with additional standardised high-speed manifolds in order to build a complete motion control system. The localised power allows for energy efficiency due to the elimination of the flow control valving and centralised piping, which should reduce the amount of wasted energy commonly found on traditional hydraulic systems.

Benefits include high force capability and force density; low environment impact due to up to 90% lower oil requirement; and low noise emission.

The system is suitable for a wide range of industrial machinery and can be used on metal-pressing applications from forging, powder and sheet metal presses to hot forming, punching and isostatic press machines. In wood and paper milling, testing and power generation applications, the system allows for decentralisation of the machine axes. Additional applications can be found in the marine sector, on operational mobile machinery, and on injection and blow moulding machinery in the plastics sector.
