Evolution of Technology
All industries are taking a critical look at the way they use motion control systems in their equipment. Where hydraulics once dominated, equipment is now increasingly utilizing electro-mechanical actuators for a large number of tasks for which they previously would not have been considered. Electro-mechanical actuators provide more precise and reliable motion, and integrate easily with modern PLCs and computers. From a complete system perspective, they are smaller, lighter, and cleaner than their hydraulic counterparts. Electro-mechanical actuators:
-
Increase efficiency, therefore reducing costly energy consumption. For battery-driven electric vehicles, this means increased battery life.
-
Eliminate hydraulic hoses, valves and pumps.
-
Have support systems that take up less space, by replacing fluid reservoirs and valve banks with compact electronic drives.
-
Eliminate the hassle and cost of dealing with spent hydraulic oil.
-
Remove the functional reliability risk associated with hydraulic fluid contamination.
-
Eliminate the safety and environmental issues of oil leaks.

Installation Savings for the OEM
-
Electro-mechanical components cost less than comparable hydraulic component from a full-system perspective.
-
An electro-mechanical actuator is easier and quicker to install than multiple hydraulic components.
-
System tuning of electro-mechanical systems is quicker and more predictable than configuring hydraulic systems.
Maintenance Savings for the End-User
-
Fewer overall components to maintain.
-
No hydraulic fluid replacement.
-
No leaks to repair.
-
Only scheduled bearing lubrication, and periodic inspection of motor/drive cables, as opposed to more complex regular maintenance of hydraulics.
