Robotic Drives - Gear Motors RD50/70/85-PG

Product Overview:

Compact drive units with industry-leading power density and a wide range of applications - with gearheads
  • Industry-leading power density
  • Compact design
  • Absolute SinCos encoder up to 12bits
  • Integrated safety brake optional
  • Wide range of transmission ratios: i=1:3,...,512
  • Low backlash
  • High output torque
  • Flexible mounting on gear or housing flange



The planetary motor gear units RD-PG provide a standardized drive solution with the powerful gearheads from Neugart. Depending on the number of stages the transmission ratio varies in a range of 1:3 up to 1:512. The gear units have a minimal, principle-conditional backlash. The RoboDrive technology allows by selecting appropriate motors to exploit the performance features of the gearheads in both: speed and torque. On request alternative voltage levels, increased speeds and optional integrated safety breaks are realizable.

We also integrate the planetary gearheads from other renowned manufacturers like Gysin or Maxon.


Basic Data

Gear motor with single stage PLE-gear i= 1:8

*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.

**Other gear ratios on request. For gearbox selection, see:

Electrical Data

All data relate to star-serial connection at Ur= 48V. The voltage level 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.
