Direct Drive Rotary Stage
DMT direct drive rotary stages are divided into super large rotary stage DDV series, ultra-thin rotary stage SDV series, high-performance rotary stage HD series, etc. according to their overall dimensions and application.
The direct drive rotary stage is an external rotor type direct drive motor with high accuracy, high speed, and high torque. It adopts the method of directly connecting the rotor and the moving carrier, and no other transitional connections (speed reduction mechanism, coupling, etc.) are used in the middle.
The advantageous load of the direct drive rotary stage is directly connected to the motor rotor, and there is no intermediate transmission structure such as a reduction mechanism, coupling, gear, and screw rod in the middle. The errors caused by these intermediate mechanisms cannot be avoided, especially for the mechanical wear caused by long-term movement. The rotor of the direct drive rotary stage is directly connected to the load, thereby eliminating the error generated by the intermediate link and achieving the optimal control accuracy. The direct drive rotary stage has strong rigidity, which is directly connected to the load to better reflect the strong rigidity on the load.
The direct drive rotary stage is suitable for indexing applications in various industrial devices, machinery, production lines, and manufacturing rotary tables for semiconductor, photovoltaic, and new energy batteries.
DMT rotary stages have the advantages of high accuracy, high response, high speed, high load,Positioning accuracy ± 2arcsec, Repetitive positioning accuracy can reach ± 1 arcsec。
