With the servo motors of the RD series RoboDrive presents high-performance motors based on the proven stator-rotor installation kits. The RoboDrive technology provides the highest power density at maximum torque range and overload capability in a compact design. The variable concept offers solutions for a variety of demanding drive applications. On request alternative voltage levels, increased speeds and integrated safety breaks are available. The integrated absolute encoder enables high positioning accuracy and excellent speed stability. The design of the mounting flange allows the combination with the gearunits of the leading gear manufacturers.

On request the motors are delivered with gearunits of Neugart, Wittenstein, Spinea und Harmonic Drive.


Basic Data

*Theoretical no-load rotation speeds at Ur=24V (RD38x12-VW Ur=48V). Variations can arise from operation with different inverters.

Higher rotation speeds or change of the voltage level can be achieved by changing the connection scheme.

Electrical Data

All data relate to star-serial connection at Ur=48V. The voltage level can be altered on customer request.
