Miniature Rotary Stage is Driven by Compact High Speed Piezo Motor | |
17 Sep 2013 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 1800 RPM (1080 deg/sec). 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.
