The main purpose of this paper is to generalize axis tracking drive type of 8~10 diameter class ground-based/infrared telescopes which already existed and will soon complete in the world, and to summarize 30~100 diameter class extremely telescopes which was pre-researching, and to analyze the development trend of future giant telescopes under construction. Tracking platform is to reduce the cogging...
In order to realize high precision control of the mount servo system for modern large-scale optical astronomical telescopes, direct drive control technology was adopted, motor was directly coupled to the load together, it saves the transmission part between them. The torsional stiffness of giant telescopes tracking axis was improved, simplified telescope structure, improved tracking telescope precision,...
