Miniature Closed-Loop Linear Stage Solutions: https://www.pi-usa.us/en/products/pre... Q-motion closed-loop miniature linear motion stages use stick-slip piezo inertia motors to permit the design of the smallest class of precision motorized positioners. The direct drive motors are only a few millimeters in size, there are no gears, and other conventional power transmission components involved that add size, complexity, play or backlash. Stick-slip (inertia) piezo motors make use of the difference in the static and dynamic friction coefficients between two surfaces; their controllers provide a quasi sawtooth output voltage, with a slow expansion phase and a fast contraction phase. In the expansion phase, the piezo actuator moves the slider; in the contraction phase, its inertia prevents the slider from following the quick motion of the actuator, and it remains at its position.
