DD Series

Synchronous servo motors for cyclical positioning of small masses – modular and highly dynamic


Thanks to their modular design, the servo motors of the DD series can be quickly configured and individually expanded. The DD series comprises two sizes and various lengths. In both cases, the A-side fixed bearing of the shaft prevents its expansion in the direction of the mechanics. This protects the machine while enabling direct attachment without a coupling. The power supply and the transmission of the digital encoder signals can be carried out either via two cables or via hybrid cable (Hiperface DSL). The single-cable solution reduces cabling effort and takes up less space in the machine.

Reduced space requirements, lower costs

The stator windings are encapsulated, thereby optimising heat dissipation. The motor is convection-cooled, and in combination with fan or liquid cooling, achievable continuous output is increased. Efficiency can be optimised by means of a customised design of the winding.


The motor has a significantly reduced moment of inertia due to its design. In this way, it accelerates quickly and increases the productivity of the application – these tend to be machines in the packaging, plastics or textile industries, or for woodworking or robotic solutions.
