Piezo Stages & Positioners: Flexure Direct Drives, Piezo Motor Long Travel Designs

PI offers several piezo-based positioning concepts. Flexure-guided stages provide the highest precision and speed, but are limited to typically <1 mm travel range. Several piezo motor concepts are offered for long travel ranges. Ultrasonic piezo motors provide higher speed, PiezoWalk motors excel in force generation, and stick-slip motors are very compact and cost effective.

Hexapod 6-Axis Positioners and Motion Platforms (Stewart Platforms)

Hexapod parallel positioners provide extremely versatile multi-axis motion in all degrees of freedom. They are based on a 6-axis (XYZ, Pitch, Roll, Yaw) actuator system, arranged in parallel between a top and bottom platform. PI Hexapod positioners and motion simulators have many advantages over conventional multi-axis stages, such as improved dynamics, smaller package size and higher stiffness.

Precision Air Bearing Stages, Components, Systems

Air bearings provide frictonless motion with excellent guiding precision (flatness/straightness) over long travel ranges, and with high load capacity. PI's air bearing stage designs are based on more than 200 man years of experience.

Miniature Positioners: Stepper, Servo, Voice-Coil, Piezo Motor-Driven

Because one drive principle does not fit all applications, PI provides a number of different miniature stage concepts. From classical stepper and servo motors to high-speed linear motors and a variety of self-locking piezo motors with emphasis on precision, dynamics, cost and force generation.

Automation Actuators / Precision Actuators

PI currently offers a variety of automation and high precision actuators based on several drive technologies. Voice coil linear motors provide high speed long travel and long service life. Piezo flexure actuators can move in microseconds to milliseconds with ranges to 1 mm. Ultrasonic piezo high-speed motors cover ranges to 150 mm and acceleration to 10 g, based on a self-locking, non-magnetic drive principle. Serve and stepper lead and ballscrew actuators cover many traditional applications and piezo ratchet drives replace conventional manual micrometers.

Piezo Actuators, Stacks, Tubes, Benders: Direct Motion, Short Travel, Ultra-Fast

PI designs and manufactures all of its piezo actuators from the ground up. Piezo materials are manufactured at PI's Ceramic division. PI's PICMA multilayer stacks have been life tested by NASA/JPL for 100 billion cycles. Stacks and benders are available in both cofired multilayer (low voltage) and classical, glued designs.

Piezo Motors: Long Travel, Ultrasonic, Stick-Slip, PiezoWalk Drives

Piezo motors provide several advantages over conventional motors: smaller, lower energy consumption, self-locking at rest, high force compared to size, intrinsically vacuum-compatible and non-magnetic, very fast response down to the microsecond range.
