Abstract

With the breakthrough development of telescope aperture, the structural weight of telescopes has significantly increased. Adopting a segmented torque motor direct drive system is an inevitable trend in the development of large aperture telescopes. The performance of the motor used for driving directly affects the pointing and tracking accuracy of the telescope. This paper focuses on the analysis of factors affecting the electromechanical integration performance of segmented motors in large aperture telescope. It covers four aspects: segmented motor integration technology, shaft support technology, high-precision position sensing technology and high-performance servo drive technology. By thoroughly exploring these influencing factors, reliable technical support is provided for the subsequent design of integrated segmented motor tracking frameworks for large telescope and electromechanical integration performance testing.
