PI (Physik Instrumente) L.P. introduces a new ultra-low profile (0.6”), direct-driven, high-speed rotary stage based on its proprietary PILine® piezomotor drive technology at this year’s SPIE Photonics West conference. The new ultra-low profile (0.6”), direct-driven, high-speed rotary stage is based on PI’s proprietary PILine® piezomotor drive technology.
The M-660 PILine® rotation stage allows high positioning speeds to 720 degrees /sec. It also features a very low profile of 15 mm (0.6″) and a 35 mm Ø clear aperture
The M-660 stage reaches top speeds of 720 degrees/sec. and resolution to 40 µrad (8 arcsec). Its self-locking ceramic drive holds the position steady at rest, with no energy consumption and heat generation. A directly coupled precision optical encoder provides phase lag-free, backlash-free feedback to the servo controller.
Features & Advantages
* Max. Velocity 720 °/s, Unlimited Travel Range
* Low Profile: Only 15 mm (0.6”)
* Self-Locking Ceramic Direct Drive: Energy Saving & High Position Stability
* Direct Metrology Linear Encoder, 40 µrad Resolution (8 arcsecs)
* PILine® Drive: Non-Magnetic, Vacuum-Compatible Working Principle
* Compact Combinations with Linear Stages Available
The compact design with minimized mass and inertia provides high precision bidirectional speed and position control, as well as high speed motion contouring. The M-660 is based on the new U-164 Piezo Motor and outperforms the stability, acceleration and settling speed of traditional servo motor direct drives and gear-driven mechanisms. The innovative motor drive was also chosen by Leica Geosystems AG’s in their newest generation of surveying instruments for geodesy, because it can provide significantly higher speeds, shorter positioning times and a very high positioning accuracy when moving the measuring optics.
A newly designed piezo motor controller is available to take advantage of the specific motion characteristics of ultrasonic ceramic motors. USB interfacing and a solid software and driver package for seamless integration are included.
