Paper Abstract
Direct drive technology is the key to solute future 30-m and larger telescope motion system to guarantee a very high
tracking accuracy, in spite of unbalanced and sudden loads such as wind gusts and in spite of a structure that, because of
its size, can not be infinitely stiff. However, this requires the design and realization of unusually large torque motor that
the torque slew rate must be extremely steep too. A conventional torque motor design appears inadequate. This paper
explores one redundant unit permanent magnet synchronous motor and its simulation bed for 30-m class telescope.
Because its drive system is one high integrated electromechanical system, one complexly electromechanical design
method is adopted to improve the efficiency, reliability and quality of the system during the design and manufacture
circle. This paper discusses the design and control of the precise tracking simulation bed in detail.
