Physik Instrumente (PI) L.P. (Auburn, MA) has introduced the M-660 rotary table driven by piezo motors that enable a profile of 14 mm. The table is equipped with a direct measuring en coder. It can accelerate to velocities of 720 degrees/sec. and its directly coupled optical encoder resolves position down to 4 μrad, providing phase-lag-free, backlash-free feedback to the servo controller. A self-clamping ceramic drive provides high stability.
