PI offers a great variety of linear stage positioning systems for micro and nano precsion requirements.
Nanopositioning linear stages can be based on three different principles: piezo drives with frictionless flexure linear guides; magnetic linear motors with air bearings; and "bearing free" - guided by magnetic levitation. PI offers all three solutions.
Micropositioningmotorized linear stages are based on rotary stepper and servo motors or linear motors, guided by cross roller and linear bearings.
Several types of drives are available: Rotary stepper motors, rotary servo motors (brushless and brushed), servo motors with gearhead for higher torque/resolution, magnetic linear motors and piezo linear motors. With piezo linear motors, drive screws, gears and coupling elements are not required, reducing size and complexity while increasing reliability at the same time. Piezo motors are self-locking at rest providing excellent long term stability.
Position feedback is provided by linear encoders or motor mounted rotary encoders.
Benefits of working with PI: Access to the broadest and deepest portfolio of precision motion technologies in the world; engineers who understand your applications and match it to the appropriate motion technology, be it a stepper motor driven lead screw system or a compact piezo linear motor drive.
PI's selection of Compact Linear Stages and rotary positioners provides high precision motion in a very small package.
