Servo actuators have better dynamic
response
The hollow shaft design of Inmoco's new Bautz servo linear actuators reduces weight significantly, providing improved dynamic response and enabling travel velocities up to 500mm/s to be achieved.

Control, I/O and networking in a single unit
Simplified and total machine control, integrating servo/stepper control, analogue and digital I/O and communications, is now available in one package with the new MultiPro controllers
This facility increases, significantly, the lifetime of the actuator's support bearings and the reliability of the actuator as a whole.
The Bautz MS/WS series combines the advantages of a highly dynamic servo motor with a spindle system in a three motor range that produces high thrust linear forces, from 2600 N to 11300N, across stroke lengths of up to 120mm.
The actuators operate in closed loop and can be fan or water cooled, depending upon their duty cycle and the continuous thrust required.

Servomotor, roller screw and encoder combined
The unique new GS40 linear actuator from Inmoco combines a brushless servomotor, an inverted roller screw and an encoder/resolver feedback source into a single compact assembly.
They also possess a high degree of protection for operation in varying environmental conditions The MS/WS actuators deliver smooth, fast and precise actuation and positioning without any of the problems of pipe runs, leaks or noise that are encountered on hydraulic and pneumatic actuators.
In addition, they offer lower maintenance and installation costs when compared to actuators using fluid mediums.
The MS/WS servo actuators provide advantages in applications where the positioning behaviour of conventional linear actuators is too inflexible and their force control or build up force is to slow or non-linear.
With the MS/WS series there is neither any delay in force generation nor any non linear dependence of thrust force and actuator position within the process.
Moreover, the servo drive provides a high overload capability to absorb any momentary force surges.
To enable users achieve the optimum equipment specification for their application, the spindle of the linear actuators is available with a ball, rolled or trapezoidal thread.
The spindle is supported by a new bearing system, which by absorbing radial forces, lengthens its own operating life and the reliability of the actuator system as a whole.
For applications where direct linear positioning of the spindle is required a high resolution resolver can be mounted on the blind hole rotor of the shaft servo motor.
Finally, the spindle system can be lubricated by a special reservoir fitted with an automatic lubricating system which gives the advantage of a nearly maintenance free operation without service interruptions.
With their compact construction, inherent precision and thrust capabilities the Bautz actuators are ideally suited to such applications as automated welding, web tension control, edge guiding, valve control, indexing and diverter control and spooling applications.
