Wittenstein - Galaxie® Actuator

The Galaxie® Drive System is an ultra-compact actuator designed to work as a precision drive in applications requiring very high performance.  The system delivers unprecedented torsional rigidity, thanks to our new gearbox design that ensures zero backlash, optimal synchronization accuracy and exceptional repeatability. The surface contact generated by the individual teeth increases the torque density of this compact actuator several times over.

The system features the gearbox and an axially or radially integrated synchronous motor with a standard encoder system. The system is easily integrated, and is available in the full-size Galaxie® D or the compact Galaxie® DF.  Holding brake and additional sensors are available as options.
