LINEAR TELESCOPABLE ELECTROMECHANICAL CONCEPTliteECO® INTEGRATED linear actuators
SMELA liteECO® series are the most compact electromechanical alternative to pneumatic short-stroke cylinders due 
to their patented telescopic concept of motor and mechanics. This makes them ideal for linear movements often 
required in production lines, machine tools or packaging systems. 
A servo motor incl. positioning sensor enables the movement of simple to complex profiles: for fixing, adjusting, 
locking and following any motion profile. The highly efficient motor not only saves up to 90 % of the energy 
compared to pneumatic systems. Together with the smart arrangement of the mechanics, it saves up to 80 % of 
installation space compared to existing electrical solutions. In addition, the liteECO® series offers the possibility of 
a simple refurbishment. Replacing worn mechanics is very easy and helps the drives to achieve several life cycles: 
sustainable, cost- and resource-saving.
In addition to the servomotor and the linear mechanics, the LE-INTEGRATED actuators have an integrated motion 
controller based on 24 volts and optionally on 48 volts. The actuators are controlled via EtherCAT, CANopen or 
digital IOs. As with the BASE series, many advantages of electric drives are combined with essential features for high 
industrial requirements and packed into the smallest possible installation space. In addition to sealing to the degree 
of protection IP65, conventional M8 and M12 circular connectors have been integrated in the codings A, B, L and 
Y. The maximum stroke is 85 or 115 millimetres, whereby any positioning within the maximum stroke is possible.Most compact pneumatic alternative for short stroke movements1 Overview

Explanatory footnotes:
1) Limit load capacity: max. static force and axial load capacity of the internal mechanics;  
    exceeding loads are not permissible and must be absorbed by external mechanics or brakes
2) The backlash is wear-dependent, the wear is dependent on load and dynamics
3) Maximum permissible force and the corresponding proportional phase current must not be exceed in order to protect the internal mechanics.  
    The max. phase current of the rotary motor Imax may furthermore be applied for max. 20 seconds in order not to exceed  
    the internal limit temperature starting from an initial temperature of the actuator of 20°C
4) Permissible permanent nom. force / permissible nom. phase current not to exceed the internal limit temperature at an embient temperature of 20 °C 
     Determined by a slow and permanent movement under load (quasi-static method) for the normal case, i.e. the connection of the actuator   
     to a metal body with a thermal contact resistance to air of 1.7 K/W. In case of a worse thermal coupling, limit to the nom. current of the worst  
     case (3 A, see chart on page 8 and footnote 11)
5) The max. speed depends on voltage. The characteristics shown refer to a nom. voltage of 24 V (at the actuator);  
6) During braking (negative acceleration), energy is generated and fed back into the DC link; if the DC link is not capable or regenerative braking,  
    care must be taken to ensure that the DC link capacitance is adequately dimensioned and that an additional braking resitor is used 
7) Over the stroke of 45 mm with a rated voltage of min. 24 V (at the actuator), without loadMechanical performance data  
Size | Flange width 50
The following maximum achievable performance data are based on the permissible load capacity for the thread 
pairs used and the motor. Limiting parameters are, among others, the static load capacity of the nut configuration, 
the permissible sliding speed and the permissible peak and nominal currents of the integrated servomotor (see fol -
lowing page). In practice, due to the reciprocal effects of influences, it may not always be possible to reach the limit 
values, in particular peak force and maximum speed cannot occur simultaneously. Any increase in the load leads to 
a reduction in the permissible sliding speeds and vice versa. Please do not hesitate to ask us about the technical 
feasibility of your motion profiles.
