Different Direct Drive Principles with 3-Phase and Piezo-Electric Motors

High Performance Rotation Stages for Industry and Research
The PI Group provides a variety of direct drive rotation stages and worm-gear driven goniometers and rotary stages, designed for a large spectrum of automation and research applications. High speed, high performance rotation stages are equipped with 3-phase electromagnetic motors and mechanical bearings or air bearings – for frictionless and maintenance free operation with the highest accuracy and geometric precision. Our extensive knowledge in the design and manufacture of highly precise rotation stages and multi-axis positioning systems has helped many customers solve precision motion control problems in variety of applications, including optical metrology, precision automation, beamline instrumentation, fiber-optical alignment, semiconductor inspection, bio-medical instrumentation, and X-ray crystallography.

The advantage of working with PI is the access to a large variety of different drive and guiding technologies.

Highest performance is guaranteed through the complete control of the design and machining process, the selection of components and assembly. Our air-bearing rotary stage selection is the most accurate in the industry with minimized eccentricity and wobble, while providing the highest repeatability and accuracy. A variety of motors and drive principles are available from stepper-motor driven worm gear designs to direct drive closed-loop torque motors. Low profile piezo motor stages provide self-locking capabilities with zero jitter, drift and no holding current at rest.
