Moog Industrial Group released the new Moog Modular EAS, as a highly flexible system with great scalability and variability. It can be easily adapted to numerous types of industrial manufacturing machinery. The Modular Electrohydrostatic Actuation System comes with standardized modules including a broad choice of customization options. This allows for extensive application potential by meeting the specific requirements of the customer. 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.

An expandable system

In order to expand the system, the basic module can be combined with various options or adapted with additional standardized high-speed manifolds to build a complete motion control system. With the Modular EAS System the localized power allows for improved energy efficiency due to the elimination of the flow control valving and centralized piping, which reduces the amount of wasted energy commonly found on traditional hydraulic systems.

Modular EAS features and benefit

Moog EAS comprises high force density that provide a compact and performant alternative to EH and EM actuation. It is environmentally clean due to up to 90% lower oil requirement compared to the standard systems and low noise emission for quiet machine operation. It comes with a small number of components to reduce the risk of breakdown and allow for faster maintenance. The system is decentralized, this means that it eliminates the need for a large hydraulic power unit (HPU) and reduces piping. Moreover, its 4-quadrant operation technology allows for universal suitability for a broad range of challenging applications as well as for effective energy management with reduced consumption due to energy recuperation. Last, the low mass inertia of the EPU provides high system dynamics.
