Moog releases modular electrohydrostatic actuation system

Increasing the response rate of hydraulically actuated test systems can be beneficial to maximizing both test efficiency and accuracy. Hydraulic systems specialist Moog’s new Modular electrohydrostatic actuation system (EAS) is claimed to assist in this by providing decentralized hydraulic power.

The modular EAS features standardized modules with a wide number of customization options available. This, notes the company, enables extensive application-specific customization, with the most basic module consisting of a manifold and an electrohydrostatic pump unit (EPU) which is delivered as an assembled and tested unit.

To expand the system, the basic module can then be combined with various options or adapted with additional standardized high-speed manifolds, in order to build a complete motion control system.

The use of 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. Moog says that the EAS System is suitable for a wide range of uses including testing and power generation applications, where it allows for improved decentralization of the machine axes.
