Galaxie® actuator miniaturized

  • Miniaturized Galaxie® actuator with axial function principle

Probably the most compact hollow shaft actuator with the highest rigidity

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, electrical connection and feedback system – and it is also easy to integrate.

1) Torsional rigidity:
Ct21: Average gradient of the hysteresis in the range of 50 to 100% of Tmax
K1: Average gradient of the hysteresis in the range below 10 Nm for SAG090 and below 15 Nm for SAG110
K2: Average gradient of the hysteresis in the range between 10 and 25 Nm for SAG090 and between 15 and 50 Nm for SAG110
K3: Average gradient of the hysteresis in the range over 25 Nm for SAG090 and over 50 Nm for SAG110
