Direct-drive rotary translation stages from LBTEK integrate a three-phase brushless direct current motor directly into the stage housing, enabling direct motor-driven stage rotation without intermediate mechanical transmissions and eliminating backlash from mechanical drives. A 23-bit high-resolution encoder provides a repeatability of up to 0.0016° and a positioning accuracy of 0.007°. The winding design of the electric motor eliminates torque fluctuation caused by magnetic cogging, maintaining good speed stability even at low speeds. Precision-engineered bearings and tight manufacturing tolerances achieve 15μm end-face runout and 15μm radial runout. This stage series is recommended for use with the ESM-CVx-series desktop brushless servo controllers, which support secondary development in programming languages such as C/C++, LabVIEW, C#, and Python.
