摘要	High-precision turntable is widely used in many occasions such as precision machinery, spectrometers, optical equipment and high-end CNC machine tools. The turntable which bears the rotation of the spectral components in the Raman spectroscopy should satisfy the requirements of large rotating range, higher resolution, higher angle position precision and faster rotational speed. However, it's hard to meet all the above requirements through the traditional driving methods. A high-precision turntable is presented which employs torque motor direct driving technology. As known to all, the precision of general methods is largely dependent on the measurement accuracy of the feedback element. In order to address this problem, a more accurate error compensation correction technology is adopted and the error measuring system is set up to compensate the measured absolute angular error through a certain control algorithm. The effect of the structural design and error compensation correction are detected in the experiment. The result shows that when the measurement pith is 1, the bidirectional absolute positioning accuracy is better than 1.008. When the measurement pith is 10, the bidirectional absolute positioning accuracy is better than 0.648 " and the axial shaking error of rotating shaft system is less than 5 ". The above results show that the turntable has high mechanical precision, high angular resolution, accurate positioning and other technical advantages, which satisfies the demand of the Raman spectrometer and other related instruments. 2016, Science Press.
