Frequently asked questions

            How fast can the liteECO® actuators proceed?

             
             
            The liteECO drive series delivers a max. speed of 1040 mm/s. With a max. acceleration of 60 m/s² a positioning time of up to 65 ms on 50 mm stroke is possible.











            Maximum force

            What force can a liteECO® actuator apply statically and dynamically?

             
             
            Depending on the actuator configuration, forces of up to 600 N 
            can be applied statically (60 kg vertical load). The nominal force for dynamic processes is 33 % (poor thermal connection) to 50 % (good thermal connection) of the maximum force. For dynamic loads, the maximum load capacity must not be exceeded. Contact us to calculate your individual motion profiles.






            Recommended motion controller

            With which motion controller can the liteECO® actuators be operated?

            The liteECO® actuators are tested with motion controller from the following manufacturers:

            Maximum stroke
            What is the maximum stroke of a liteECO® actuator?

            The currently offered series models provide a traversable stroke of up to 56 mm (without integrated anti-rotation protection of the plunger). The overall length of the actuator in this configuration is 84 mm. The liteECO® saves up to 80 % installation space compared to comparable electrical solutions and uses 2/3 of its installation length for the stroke.
            Scaling to a longer stroke is possible on request. Contact us!

            What are the benefits of switching to an all-electric infrastructure?

            The use of electromechanical actuators instead of pneumatic systems leads to a significantly simplification of the system infrastructure and an associated faster commissioning. The reduced component use leads to a more advantageous ecological footprint of the systems.

            Whereas the SMELA liteECO® actuators only require a motion controller, a pneumatic cylinder requires a complete compressed air infrastructure consisting of a compressor, pressure vessels, leaky hoses, valves, valve actuators as well as a power supply.

            The maintenance effort of these compressed air systems, with continuous lubrication and cleaning as well as filter changes and leakage repairs, represents a non-negligible personnel expense with additional material costs.


            Mechanical compatibility
            How is the mechanical connection of the liteECO® actuators designed?

            The LE48 size has an external flange dimension (A) of 48 x 48 mm with a mounting hole spacing of 38 x 38 mm. This corresponds to a comparable pneumatic cylinder with a piston diameter of 40 mm. Since the liteECO® series does not exceed the installation length with the same stroke of the pneumatic cylinders, the actuators can be used without further adaptation effort. Provided that the force and dynamics are in accordance with the requirements.

            Can the movement processes be parameterized?

             
             
            Depending on the motion controller used, various scripts for standalone/island operation of the controllers can be stored in addition to the integrated position control with mostly subordinate speed and current control loop.

            This means that, in addition to setpoint specification via a bus system (e.g. CAN, EtherCAT, Profinet or Profibus), digital or analog inputs can also be easily evaluated and used in programmed state machines.

            This can be useful and helpful for small systems/automats without higher-level control or for quick commissioning by mechanics without programming knowledge.

            The adjacent video shows a simple switch function for picking and logistics systems. The desired positions can easily be programmed by hand, without PC or bus connection. The control in the machine can be done via digital inputs (pushbuttons), binary signals or bus systems.
            Lifetime
            How high is the life expectancy of the liteECO® actuators?

             
             
            The utilized mechanics are made of high-performance plastics or ball screws, depending on configuration. The former are cheaper to manufacture and more susceptible to wear, although dynamic load tests have proven cycle numbers similar to pneumatic cylinders (> 10 million). A resulting wear can be compensated and announced electronically by the control system (predictive maintenance). SMELA offers a refurbishment of the actuators to easily and cost-effectively replace the mechanics and help to achieve multiple life cycles. Thereby our sustainable design not only conserves valuable resources, it also reduces industrial scrap.

            Areas of application

            Where are liteECO® actuators used?

            The liteECO® linear actuators are ideal for applications that require short linear movements: e.g. in production lines, machine tools or packaging systems. For simple and complex movements: for fixing, adjusting, locking or traversing any motion profiles.
