Miniaturized Galaxie® actuator

Miniaturized Galaxie® actuator – Hollow shaft actuator

Miniaturized Galaxie® actuator shines with precision and integration in the smallest of spaces. This is the solution for applications that require compact integration and maximum accuracy. With its large hollow shaft, it allows cables and media to be fed through directly, creating additional design freedom. The innovative zero-backlash kinematics ensure constant positioning accuracy over the entire service life – ideal for innovative machines and robots where space and efficiency are crucial.

* Please note that the maximum motor current can lead to a higher acceleration torque than the permissible maximum acceleration torque.
1) Torsional rigidity:
Ct21: Average increase of the hysteresis in a range of 50 to 100% of Tmax
K1: Average increase of the hysteresis in a range below 10 Nm for SAGM090 and below 15 Nm for SAGM110
K2: Average hysteresis gradient in the range between 10 Nm and 25 Nm for SAGM090 and between 15 and 50 Nm for SAGM110
K3: Average increase of the hysteresis in a range over 25 Nm for SAGM090 and over 50 Nm for SAGM110

The unit Nm/arcmin can be converted into 104 Nm/rad using a factor of 0.3438.
