On demand | Presented live 19 June 2024 
Abstract
With the breakthrough development of telescope aperture, the structural weight of telescopes has significantly increased. Adopting segmented torque motor direct drive is an inevitable trend for the development of large-aperture telescopes, and the performance of the motor used directly affects the pointing and tracking accuracy of the telescope. This article focuses on the analysis of factors affecting the integrated performance of segmented motors in large-aperture telescopes, covering four aspects: segmented motor integration technology, axis support technology, high-precision position sensing technology, and high-performance servo drive technology. By delving into these influencing factors, reliable technical support is provided for subsequent integrated design of segmented motor tracking frameworks and performance testing of electromechanical integration..
