ALMA Project

Case History

Motorization of large telescopes

The quality and precision of the movement obtained with our motors have enabled Phase to produce many direct drive applications for telescopes.

For the ALMA radio telescope project, the company has developed very large direct drives with double axial air gap, with integrated power electronics in each sector.

ALMA is the most ambitious radio astronomy project undertaken so far worldwide. It consists of 56, autonomous, giant submillimetre radio telescopes installed on a 5000 meters altitude plateau in the Atacama Desert in northern Chile. The telescopes can be operated synchronously to obtain the highest resolution, in the order of milliarc second.
