Linear servo actuators convert the rotary motion of the servomotor into a linear motion (stroke).

 

The external form of the actuator is oriented towards the usual design for pneumatic or hydraulic cylinders, thus facilitating a conversion of existing equipment.

 

 

The advantages are obvious:
 

Energy savings
Lower operating and installation costs, thanks to the use of cheaper electrical drive energy instead of a pneumatic or hydraulic system.
 

 

Enhanced processing flexibility
The control options that are offered by servo systems make it possible for the actuator to be positioned at will a precondition for flexible production installations.
 

Improved thrust control
Optimum control of power and a linear build-up of the force. In this way, there are no delays in the build-up of the force or non-linear dependencies of thrust and actuator position that have to be allowed for in the process.
 

Higher performance drive unit
The overload capability of a servo drive enables it to absorb short disturbances (peak forces). Furthermore, the driving cylinder does not have to be dimensioned for the peak force, as is the case with pneumatic systems, but can be dimensioned for the effective force.
 

Shorter cycle times
The fast build-up of the thrust enables shorter machine cycle times.
