Overview

Modern machine designs are increasingly based on Electrohydrostatic

Drive Systems (EAS) instead of valve-based throttle control.

The installed power of the EPU axes and their servo controllers often

exceeds the connected load of the previously used hydraulic power

unit, especially when conventional hydraulic accumulators are used.

Moog combines the best fitting power infeed with storage units to

reduce the installed power significantly. Together with the efficiency

gain of the EAS and the peak power reduction of the Moog Energy

Management System (EMS), hydraulic machines reach a new level

of attractiveness in terms of energy efficiency and reduced total cost

of ownership (TCO).
