MOOG ENERGY MANAGEMENT SYSTEM (EMS) FOR EAS

Modern machine designs are more and more based on Electrohydrostatic Actu

ation Systems (EAS) instead of valve-based throttle control. During this trans

formation, the installed power of the used EPU-axes and their Servo Drives

often surpass the power of the formerly used hydraulic power unit, especially

when hydraulic accumulators were 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, hydraulic

machines reach a new level of attractiveness.

The Energy Management System as add on to EAS provides multiple benefits

to machine end-users and to OEMs. Additionally, the EMS can also be used for

electromechanical actuation systems.

MOOG EVALUATION PROCESS

Through in-depth simulation of the application including energy management,

the best fitting storage and infeed is evaluated. In this process the customer is

pro-activly consulted on energy savings, grid loading and amortization, amongst

others.

ADVANTAGES

• Reduces installed power significantly and thus in-line components up to the

transformer (peak shaving)

• Maximizing machine efficiency through energy storing and minimizing losses

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

APPLICATIONS

• Material testing and simulation platforms

• Cyclic high pressure compression axis

• Metal forming and presses
