Piezomotor Rotary Stage has low-profile, high-speed design.

Press Release Summary:




Based on PILine® piezomotor drive technology, M-660 direct-driven rotary stage has 0.6 in. profile and reaches speeds of 720°/sec while offering resolution to 40 µrad (8 arcsec). Self-locking ceramic direct drive holds position steady at rest, with no energy consumption or heat generation, while direct coupling optical encoder provides phase lag-free, backlash-free feedback to servo controller. Solution also provides bidirectional speed/position control and motion contouring.



Original Press Release:



PI Launches Lowest Profile, High Speed Piezomotor Rotary Stage at Photonics West



San Francisco, CA, 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

Fast, Self-Locking, Direct Drive, Direct Encoder
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.

Ceramic Drive Used in the Latest Generation Optical Instruments
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 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 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.
