Future-proof Automation Technology
Efficient positioning, assembly and handling applications are key components in many manufacturing companies to counter growing cost pressure. Replacing pneumatic positioning systems with electric linear technology can save up to 90 % of energy consumption, because no energy needs to be supplied when the system is at a standstill.
IAI has the world's largest portfolio of electric linear actuators, from mini types, short stroke cylinders, rod and slider types to servo presses, rotary axes and grippers for almost all technical applications. They perform linear, rotary or even gripping movements in pick & place applications, for example.
EleCylinder - RoboCylinder - IntelligentActuator
IAI portfolio of electric axles consists of the new low-priced EleCylinder series with built-in controller. It replaces conventional pneumatic cylinders quickly and easily.
By far the largest share of the product portfolio have the high-quality product lines RoboCylinder and IntelligentActuator single-axis robots. Both product lines consist of highly accurate electrical axes for a wide range of automation requirements.
In the RoboCylinder series, the focus is on miniaturization and handling of small payloads, which is reflected in significantly lower prices compared to the IntelligenActuator single-axis robots. The latter, for example, meet significantly higher requirements in terms of payload, speed and stroke length.
Savings potential of up to 90 percent
Traditionally, companies often use pneumatic actuators because of their low investment costs. However, the generation and distribution of the necessary compressed air is associated with very high losses. Of course, intensive optimization measures can also be used to optimize compressed air systems for energy efficiency.
Nevertheless, technological limits are reached quickly here. In these cases, a so-called substitution scenario offers itself: In this case, the pneumatic positioning systems are replaced by electromechanical ones.
Various scientific studies have already provided the following proof: Such a substitution is clearly preferable to the optimization of compressed air systems in view of the economic and ecological savings in energy consumption. In individual cases, savings of up to 90 percent could be demonstrated here. The effective efficiency reaches 80-90%, while the typical overall efficiency of a pneumatic system is only about 10%.
Other convincing advantages
Compared with pneumatic drives, electric drives offer a whole range of advantages: they are insensitive to load fluctuations, enable smooth starting and stopping, simple speed regulation and the control of various positions with the highest repeatability.
IAI's electric axes and grippers are also characterized by an easy-to-use control system.
The sustainable energy efficiency, the significant cost savings over the entire life cycle of the production plant as well as the outstanding technical advantages in the motion control are the clear arguments for a substitution of pneumatically driven actuators by electromechanical systems.
