	Study on the Driving Scheme of a 4-m Alt-azimuth Telescope (EI CONFERENCE) 会议论文 OAI收割 3rd International Symposium on Advanced Optical Manufacturing and Testing Technologies, AOMATT 2007: Large Mirrors and Telescopes, July 8, 2007 - July 12, 2007, Chengdu, China 作者: Zhang J.; Dai S.; Zhao Y.; Zhao Y.; Zhao Y. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 By summarizing the corresponding parameters Of the driving system of a 4-m Alt-azimuth telescope some unit techniques like the driving modes and structure angular position measurement methods in detail have been analyzed in the paper. A set of primary schemes for astronomical applications including the altitude axes being driven by 2 DC torque motors the azimuth by 4 DC torque motors using helical gears and two pieces of the 27-bit segment tape encoders for each set of axes is proposed. To meet practical engineering needs the shafting motion parameters are designed and motor elementary parameters are primarily calculated to offer the important references for further study on system driving model and prototype development.
