Motorized Positioning Stages
Piezo Motors Enable Tiny Closed-Loop Nanopositioning Stages
New Scale’s closed-loop linear stages and multi-axis positioning systems feature integral SQUIGGLE motors to provide
unmatched precision in a very compact and precise design.
The stages support vertical loads of 200 to 500 grams with high stiffness and negligible heating. They are ideal for
hands-free, “set and hold” positioning where space is at a premium, such as in optical microscopy, automated laser
alignment, and biomedical research.
New Scale closed-loop stages are easily assembled into multi-axis (X-Y and X-Y-Z) nanopositioning systems.
The SQL-3405 is the smallest closed-loop positioning stage on the market. Its long 5 mm travel
range provides for automated positioning without manual pre-alignment.
The SQ-2115 is a 20-nm resolution closed-loop stage that integrates a piezoelectric SQUIGGLE
motor with crossed roller bearings and glass scale encoder.
Motorized Stage Drive Electronics
We offer both benchtop controllers for laboratory use, and credit-card sized PCB drive cards for easy
integration into OEM systems and instruments. Controllers accept
analog input, an optional manual handset, or computer interface. We
provide intuitive control software, along with an ActiveX control
that you can integrate into your own applications written in
languages such as C++ or Visual Basic. See the
motor controllers page for more information.
Commercial Positioning Stages with Piezo Motor Drive
A SQUIGGLE motor can directly replace the manual micrometer in many
commercial linear stages. A light spring preload is required to hold
a flat surface on the moving stage against the tip of the motor’s
lead screw. A knob on the motor allows for manual screw rotation and
stage positioning.
New Scale offers standard and vacuum-compatible stages with light
spring loads for use with our ultrasonic motors.
See our laboratory and vacuum piezo motor pages.

At 25 x 25 x 10 mm,
the SQL-3405 is the smallest closed-loop linear positioning stage on
the market.
The SQ-2115 closed-loop stage with integral piezoelectric motor provides 5N force and 20 nm
resolution in a 17 mm profile.
