Astronomy project • consortium of 16 universities and research institutions
The mission is to design, build, and operate the Giant Magellan Telescope to enable cutting-edge research and scientific observations that will revolutionize humanity’s fundamental understanding of the Universe.

Precise Telescope Positioning
The main-axis drives move the telescope in azimuth and elevation with high accuracy — essential for the precise positioning and tracking of astronomical objects.
Gearless Direct Drive
The drive axes use a gearless direct-drive design. This minimizes backlash, mechanical losses, and unwanted motion errors.
Segmented PMSM with Air-Gap Windings
At the heart of the drive concept are permanent magnet synchronous motors (PMSMs) with multiple stator segments. The air-gap winding design enables exceptionally smooth operation for the highest level of optical precision.
Synchronized Drive Control
All stator segments are synchronized through a precisely coordinated control system. Each segment is powered by a Kollmorgen S700 servo drive, while direct phase-current control enables precise torque shaping. EtherCAT communication meets safety requirements up to SIL 3.
