Servo actuators

Our servo actuators are distinguished by high power density, a low mass moment of inertia, high stiffness and low torsional backlash. Thanks to their outstanding technical characteristics, these servo actuators contribute decisively towards higher productivity and lower energy consumption. Our sizing tools help you achieve the optimal design for a complete drive train including servo actuators from WITTENSTEIN alpha.

Apart from the industrial sector, our actuators are also used in aerospace applications.

Servo actuators: Operating principle

An actuator is used to execute a motion precisely, dynamically and efficiently. Absolute precision meets perfect movement! The core of the motor / gearbox unit is a torsionally rigid precision gearbox with low backlash and excellent torque density in conjunction with an equally powerful, permanently excited synchronous servo motor, which guarantees low cogging and a constant speed through the distributed winding. 

Our TPM+, premo® and SPM+ / TPM+ endurance rotary servo actuators meet almost all the challenges of automation, integration and industry specifications. Servo actuators from WITTENSTEIN alpha satisfy the most exacting requirements in terms of efficiency and reliability, providing a high degree of connectivity to third-party servo amplifiers.
