About This Product

■Features

・Compact: Blade length 50mm, height 19mm ・Locate loads quickly and accurately: speed 720°/s, minimum incremental movement 51µrad ・Unlimited rotation range >360° ・Driving torque 25mNm Self-locking when switched off: saves energy and reduces heat generation. ・Central opening for more application fields

■Precision rotating stage

PILine® stages are particularly suited for applications that require high-speed, high-precision positioning. When switched off, a self-locking drive keeps the stage mechanically stable in position. Therefore, energy consumption and heat generation are significantly reduced. These characteristics are useful in low duty cycle applications that are battery powered or heat sensitive. Axis position is measured by an encoder and an optical reference switch enables reliable and repeatable motion. The piezo motor drive principle and its electrical operation are inexpensive and customizable.

■PILine® Ultrasonic Piezo Motor

An integral part of the PILine® ultrasonic piezo motor is a piezo actuator that is preloaded against a movable guided runner via a coupling element. ・The piezoelectric ceramic actuator is excited by a 100-200kHz high-frequency AC voltage and vibrates ultrasonically. - The deformation of the actuator causes a periodic diagonal movement of the coupling element relative to the runner. -The feed created is a few nanometers per cycle. -High frequency brings high speed. - Preloading of the piezoceramic actuator against the runner ensures self-locking of the drive when stopped and switched off.

■High-precision position measurement using incremental encoder

Non-contact optical encoders directly measure the platform position with maximum accuracy. Nonlinearities, mechanical play, and elastic deformations do not affect the measurements.

■Application field

Micromanipulation, automation, biotechnology, sample manipulation, sample positioning, applications in confined spaces, optical metrology, vacuum applications up to 10-6hPa (optional).
