Mini ultrasonic piezo rotary stage with integrated encoder by PI

Small, fast, and self-locking without the need of a brake, the U-62x's ultrasonic piezomotors are superior positioners that reach velocities of up to 720deg/second. Due to the self-locking ceramic motor, no heat is generated at rest. The compact design with widths of 20, 30 or 50mm and height of only 10, 12 or 19mm allows for easy integration into tight spaces of existing applications. With a rotation range of 360deg and very quiet operation, the stages excel by their extreme dynamic range and very quick step and settle.

A piezo ceramic ring motor directly drives the rotating platform eliminating the need for mechanical components, such as worms, pinions and gears, reducing inertia, size, and wear, while at the same time increasing reliability. The U-62x series comes with integrated, direct-measuring, incremental encoders that ensure resolution down to 1/1000th degree and reliable position control and repeatability.
