MOOG ESU-C Energy Management System

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).

Benefits

• Reduces installed power significantly and thus in-line components

up to the transformer (peak shaving)

• Reduces energy and operating costs and extends the service life

of electronic components

• Maximizing machine efficiency through energy storing and minimizing

losses

• Modular approach: For each application the right infeed and storage

type

SMART ENERGY MANAGEMENT FOR ELECTROHYDROSTATIC

ACTUATION SYSTEMS

As an addition to the EAS portfolio, the Moog ESU Energy Management

System (EMS) offers machine operators and OEMs the opportunity to

significantly reduce energy and operating costs while increasing the

service life of electronic components. The EMS can also be used in

electromechanical drive systems.
