The M-660 4.42-in.-diameter piezo motor rotary table can rotate at up to 720 deg/s and features a directly coupled precision optical encoder that resolves positions down to 4 µrad (0.00023°), providing phase-lag-free, backlash-free feedback to a servo controller. The table’s ultrasonic piezo motor drive allows a very-low 0.6-in. profile.
For optimum performance, the specialized C-867 motion controller is recommended. The table operates from 60 Vrms without gears or magnets and has very low mass and inertia for very fast start/stop behavior that is critical or high-speed motion contouring. (From $4.50 for a closed loop system — available now.)
