Miniaturized Galaxie® actuator: High-end performance for precision robotics

The highest levels of torque density and rigidity, excellent dampening properties, zero backlash and the largest hollow shaft – all of this is combined in the new miniaturized Galaxie® actuator from WITTENSTEIN SE, probably the most compact, all-in-one servo drive system of its kind. Thanks not least to its special overload capacity and torsional rigidity, it is perfect for surgical and high-precision robotics. The actuator’s performance parameters and features are individually configurable depending on the desired task – for instance the motor sizing, brake, connection to the application, power supply, cable connection method and feedback system – and it is also easy to integrate. The miniaturized Galaxie® actuator will be making its debut at the WITTENSTEIN booth at SPS 2024 (Hall 4, Stand 4-221).

A frameless motor from the cyber® kit line small, combined with a miniaturized Galaxie® gearbox with a hollow shaft up to 35 mm in size – the new miniaturized Galaxie® actuator unites innovative mechatronic system components in a space-saving and integration-friendly design. 
 

More precision and productivity

With its extremely high torsional rigidity, the miniaturized Galaxie® actuator – probably the most compact of its kind available today – enables high acceleration rates with less vibration and hence maximum productivity in the application. What’s more, it guarantees best-in-class precision – on the one hand, thanks to its true zero backlash and special dampening properties and on the other, through an additional encoder on the output side, which further improves control quality and precision too. At the same time, the high rigidity and power density of this modularly configurable actuator open up possibilities for downsizing the robot’s drive train, as a way to save space and weight or upgrade the application’s performance. Compared to other installation-compatible drive solutions currently on offer in the market, the large hollow shaft makes it easy to feed through cables or media supply lines. That significantly reduces the complexity of the motor-controller connection and prevents cable breakage during operation – for increased machine availability.
 

Safety integrated as standard

With its high torsional rigidity and exceptionally high emergency stop torque, the miniaturized Galaxie® actuator automatically provides crucial safety reserves. The integrated dual encoder system adds to this effect, creating system control redundancy, and is an important safety feature for axes, especially in medical robotics.
 

Miniaturized Galaxie® gearbox combinable with standard industrial motors too

Alongside the actuator solution on show at the upcoming exhibition, the miniaturized Galaxie® gearbox can also be used with standard industrial motors. Adapter plates and clamps are employed to connect them together so that, in theory, a perfect connection can be achieved for any motor. The miniaturized Galaxie® integrates quickly and easily into existing axes as a result. This solution is ideal wherever the overall length of the drive solution is not a key factor. 

The new, miniaturized Galaxie® actuator – just perfect for surgical and high-precision robotics!
