| Abstract: | High Velocity linear feed unit is a key component of zero transmission machine tools. In this paper, the construction of the GD-3 linear feed unit driven by induction linear motor is introduced, the characteristics of the control system is also analyzed, at the end of paper, the positioning accuracy, traveling velocity and acceleration of the GD-3 feed unit have also been tested experimentally. The results show that the positioning accuracy is up to 4um, the max velocity up to 80m/min, and its max acceleration is up to 16.8 m/s 2, while the traveling process is much stable. |
