Miniature Rotary Stage is Driven by Compact High Speed Piezo Motor

14 Aug 2014

The U-628 rotary stage is equipped with an ultrasonic ceramic motor for fast response and high speed.

On a very small footprint of only 2x2 inches, it provides high rotational velocity up to 1080 deg/sec (180 RPM). An optical encoder is integrated for position feedback and direct position measurement with 35 µrad resolution.

The stage also provides a small central aperture of 7mm and comes complete with an optical reference switch. A vacuum compatible version is also available.

Ultrasonic Ceramic Direct-Drive Motor

The rotary stage is driven by a high-frequency oscillating piezoelectric ceramic that also acts as a break for the stage when at rest or when the power is shut off, improving long term stability significantly.

Application examples

Opto-mecahnics, positioning of optics, polarization rotation, sample handling and positioning where space is at a premium.
