DS/DSH/DSM 050

The high precision DriveSpin DS 050 actuators represent the smallest serially produced member of the DriveSpin product range, meeting even the most demanding requirements of customers from all industries. With their optimal price/performance ratio, they reliably provide parameters such as high accuracy and precision, high tilting and torsional stiffness, low weight, compactness, low vibrations, and a wide range of suitable technical solutions.

DS 050

The DriveSpin electric rotary actuators, as the basic type of actuators, provide rotary motion and the transfer of output torque with a high radial-axial load capacity and are the most accurate and precise solution in their category. The DS actuators are characterized by high dynamics, guaranteed by an AC servomotor, and high robustness and overload capacity of their reduction gears. The voltage and feedback variability will widely satisfy all of customers’ requirements.

DSH 050

The DSH electric actuators are characterized by the possibility to use a through hole for routing cables, pipes, and drive shafts while maintaining the radial-axial and torque load capacity and the characteristic high overload capacity of the reduction gear and of the AC servomotor, featuring high dynamics. The voltage and feedback variability will widely satisfy all of customers’ requirements.

DSM 050

The DSM modular rotary positioning modules provide controlled rotary motion and transfer of torque with a high positioning accuracy and precision. The output flange of the module allows to capture both radial and axial forces. The modules feature a special design of the case, which allows versatile connections, also without additional devices. The good design integration ability and small dimensions allow to create kinematic assemblies from DSM modules for end effectors, but also for additional devices and positioners. The selection of a module size depends on the required load-carrying capacity and the number of degrees of freedom of the motion axis.
