Sub-Miniature Positioning Stages feature piezo inertia motor.
Press Release Summary:
Available in open and closed loop designs with dimensions as small as 22 x 22 x 10 mm, LPS-22 Linear and Rotation Stages offer travel ranges of ¼, ½, and 1 in. Piezo motor drive allows for push/pull forces to ½ lb and velocity to 10 mm/sec. Open-loop and encoder equipped versions offer resolution down to 1 nm. Linear stages can be combined to XY units and rotation can be added in form of RPS rotation stages. Available in 14, 22, and 32 mm diameters, rotators feature profile as low as 7 mm.
Original Press Release:
PI Group Launches Economical Sub-Miniature Precision Positioning Stages at 2014 Photonics West
San Francisco, CA – PI (Physik Instrumente) LP just introduced a new generation of economical, miniaturized positioning stages with piezo-inertia motor drives at this year’s SPIE Photonics West conference. Linear and rotation stages are available in open and closed loop designs.
Small, Self-Locking, Low Power, Nanometer Resolution
The new LPS-22 series of economical mini positioning stages are driven by a compact piezo inertia motor. They are offered with travel ranges of ¼ inch, ½ inch and 1 inch. Featuring dimensions as small as 22x22x10mm, the LPS-22 is one of the smallest precision linear stages currently available on the market.

Open-loop and encoder equipped versions are available enabling resolution down to 1 nm. The optimized piezo motor drive allows for push/pull forces to 3N (1/2 pound) and velocity to 10 mm/sec. The new linear stages can be combined to XY units and rotation can be added in form of the new RPS rotation stages. These ultra-low profile rotators available with diameters of 14, 22 and 32 mm and feature a profile height as low as 7mm. No adapter plates are required for mounting.
Applications
Optics alignment & assembly, photonics, microscopy, beam-line instrumentation, medical engineering and bio-technology
Why PIShift Piezo Inertia Motors?
The integrated PIShift type piezo ceramic inertia motors provide several advantages over classical motor drives:Â smaller, lower energy consumption, nanometer resolution and self-locking, i.e. at the end of each move, the stage locks its platform into place with no drift and no current draw. This provides better stability and removes the need for a motor brake.
Options, Drive Electronics
The stages are available in open-loop versions and with direct encoders for closed-loop operation. Vacuum and non-magnetic designs are also available. Several drive options from OEM driver boards to closed-loop servo controllers with USB interface are offered. Custom designs are also available.
