Abstract
A 30m giant telescope project, Chinese Future Giant Telescope (CFGT), has been proposed by Chinese astronomers. At present, a series of key techniques are being developed. This paper explores a method to control direct drive servo motor in giant telescope application, which is based on a segmented Surface-mounted Permanent Magnet Synchronous Motor (SMPMSM). The losses of SMPMSM and the method of reducing the losses are discussed in this paper. Phasecontrolled rectification circuit is chosen to regulate rectified voltage according to the telescope status. Such design can
decrease the losses of the motor to some extent. In the control system Space-vector PWM (SVPWM) algorithm acts as a control algorithm and three-phase voltage source inverter circuit acts as drive circuit. This project is subsidized by Chinese National Natural Science Funds (10833004).
