Rotary motors

This is our standard range of Piezo LEGS® rotary motors. Our patented piezoelectric technology gives sub-microradian resolution while direct drive ensures motion with zero backlash. These motors combine compact size with high-torque output. They hold position without drawing current and react instantly when starting/stopping.

    • Piezo LEGS® Rotary 30mNm Standard w. Position Sensor

      LR17 version A21 — Standard — With Position Sensor

    • Description

      This is our smallest rotary Piezo LEGS®, with direct drive and high torque output. The integrated 15-bit encoder gives closed loop resolution of 0.2 mrad (0.01°), while open loop resolution is sub-microradian. This motor can be fitted in many OEM applications where conventional motors cannot meet the requirements.
