Servo actuator in a hygienic design
Which product is right for your application?
Our sizing tools support you from complete product sizing to detailed calculation and simulation of multi-axis servo systems.
Our servo actuators offer precise movement, high efficiency, and compact design. Ideal for applications that require accurate positioning and fast response times—while maintaining high energy efficiency.

Compact actuators for high precision
The goal in developing our servo actuators is to reduce complexity while optimizing efficiency, safety, and connectivity.
Low moment of inertia
The significantly lower moment of inertia increases productivity and reduces energy consumption.
Highest power density
The compact power unit consisting of motor and gearbox enables high performance in significantly less installation space.
Absolute scalability
The technical properties of the unit can be scaled according to the requirements of the application.
High connectivity
The electrical interface offers connectivity to many different servo controllers.
We live and breathe mechatronics
Our servo actuators are characterized by high power density, low mass moment of inertia, high rigidity, and low backlash. Thanks to these outstanding technical properties, they can make a decisive contribution to increasing productivity and saving energy.
The function of the actuator is to execute a movement precisely, dynamically, and efficiently. Absolute precision meets perfect movement. At the heart of the motor-gear unit is a torsional-rigid precision gear with low torsional backlash and excellent torque density, combined with an equally powerful, permanently excited synchronous servo motor, which ensures low cogging and high speed stability thanks to its distributed winding.
The TPM+, premo®, and axenia rotary servo actuators meet virtually all requirements of drive technology, integration, and industry specifications.
