Robotic Drives - Hollow Shaft Servo Motors RD50 / 70/85 HW

Product Overview:

Compact drive units with industry leading power density and wide range of applications
  • Hollow shaft
  • Industry-leading power density
  • High overload capacity
  • Compact design
  • Absolute encoders with very high resolution
  • Integrable hollow shaft safety brake
  • Custom flange plates available



With the hollow shaft 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 with a maximized hollow shaft diameter in a compact design.

The hollow shaft design allows to guide signals, media and fluids, rays, and cables through the motor.

The integration of gear elements, spindle nuts or optics and serial actuators expands the field of applications.

The integrated absolute encoder enables high positioning accuracy and excellent speed stability.

The variable concept offers solutions for a variety of demanding drive applications.

On request alternative voltage levels, increased speeds and customized torque adaptations and optional integrated hollow shaft safety breaks are realizable.


Basic Data

*Theoretical no-load rotation speeds at 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 and can be altered on customer request.


Safety Brake Data

All brakes are operated with a rated voltage, UB,r=10V , to open the brake, an over-excitation voltage of 30V is required.
