Up to 250 coordinated axis stepper and brush DC servo drive.

Multi-axis precision at the right cost

The i161-01 is an advanced multi-axis motion system designed to work in a fiber multi-object spectrograph  instrument of an European telescope used for astronomy and scientific research.
The system can position miniature steppers and brush DC micro motors with submicron accuracy.



Instruments to discover the universe – Fibre multi-object spectrographs are used to look at the light from hundreds of stars or galaxies simultaneously over a wide field of view. The motion control positioning systems working in these instruments have to offer the maximum performance in the most compact package, and need to be virtually maintenance-free and available for 24/7 operation. A high resolution, and an excellent in-position stability, are also key features required for the success of the application.
