High Precision Motorized Rotation Stages - Rotary Motion

  • 360 Degree Rotation; Goniometers; Tip-Tilt Rotators; Air-Bearing Stages
Precision motorized rotation stages are used in a variety of applications from fiber-optical alignment, semiconductor inspection to bio-medical applications and X-ray crystallography.

PI miCos has extensive knowledge in the machining process, the selection of components, assembly as well as the testing high precision rotary positioners. Our air-bearing rotation stages are the best in the industry when it comes to ultra-low runout and wobble as well as extremely high resolution and repeatability. These stages are driven by torque rotary motors with feecback provided by the best Heidenhain direct metrology encoders, for extremely smooth closed-loop rotary motion. On the other end of the spectrum are miniaturized stepper-driven motorized rotation stages with worm-gear drives for laboratory use. If very high speed to 1400 deg/second is required, compact belt-driven rotation stages are the answer. Piezo motor driven rotary positioners are also available. Advantages of these precision positioners are self-locking-design, and the feasibility of non-magnetic designs.

Talk to our engineers, we will help you select appropriate technology, for your application or precision rotary motion, from the drive and bearing system to the encoder and motion controller.

Most of our positioning systems are also offered in high-vacuum and ultra-high-vacuum configurations.
