Custom engineering of ingeniously small motion systems
New Scale's engineering team creates disruptively small motion
systems that enable design engineers to create smaller products.
We work with our OEM partners to develop custom motion modules
and systems that meet your exact requirements - whether that means
modifying one of our standard products or developing a
full-custom motion module for a specific applications.
We also work with leading development partners to continuously
advance the state of the art in miniature piezoelectric motion
systems.
This page presents just a few examples.

Integrated module for optical zoom
Our custom zoom module reference design
for micro optics incorporates two SQUIGGLE
motors, two TRACKER position sensors and our dual motor drive ASIC
in a custom housing that measures only 6.5 x 13 x 23 mm. This reference design features:
- 4 mm optical zoom stroke
- 0.5 µm position resolution
- magnetic position sensor that needs no light source
- absolute position sensing (with external flash memory) - no
zero reference sensor needed

Custom autofocus module for board-mounted cameras
Our optical focus module demonstrates a customizable, precision
focus system for board cameras using M6 to M12 lenses. A SQUIGGLE
micro motor and a TRACKER position sensor are integrated into a
compact housing that can be mounted on a PCB over a CCD or CMOS
camera. Our driver ASIC controls the module. This customizable
module shows:
- 2 mm stroke
- 0.5 µm position resolution
- magnetic position sensor that needs no light source
- absolute position sensing over the 2 mm travel - no
zero reference sensor needed

UTAF™ Ultra-Thin AutoFocus actuator
New Scale's new patent-pending UTAF™ (Ultra-Thin AutoFocus)
actuators were created for phone camera applications. The UTAF saves space and height by combining the motor with the linear
guide mechanism and enables overall camera thickness less than 5 mm.
This invention is described in our technical paper, "Piezo Motor for
Ultra-Thin Auto Focus Cameras."

High-Torque Rotary SQUIGGLE motor
This custom rotary SQUIGGLE motor has twice the torque of
similar-sized DC micro motors. It needs
no gear reduction mechanism, delivering high peak torque at
sustained speeds as well as high holding torque. The patented
SQUIGGLE design uses friction to directly drive the stator and lock
it in place with the power off. This rotary piezoelectric motor also
offers higher precision than DC micro motors.
This design can be optimized for other design parameters
including smaller size or higher speeds. It is scalable to less than
2 mm diameter. The chart below illustrates
the general tradeoff between motor diameter and torque.

The high torque rotary micro motors were developed for
NASA Jet Propulsion
Laboratory's "Cobra" fiber positioner to be commissioned on the
Subaru Telescope on Mauna Kea, Hawaii in 2013.

High-torque rotary
motors created for NASA JPL produce twice the torque of similar-sized
DC micro motors.

Cryogenic and UHV motors
Custom SQUIGGLE motors have been used for active alignment of
cooled optics in cryogenic
sensors (hyperspectral imaging systems) and in a cryostat at 6
Kelvins as part of a mechanism to accurately deform a cylindrical
superconducting microwave resonator in order to change its resonant
frequency (Cryogenics,
Volume 46, Issue 9, September 2006, Pages 694-696. (Free access
to Elsevier subscribers, $30 to non-subscribers, or
email us to receive a copy for personal use.
We have developed custom
ultrahigh vacuum motors for operation down to to 10-10 Torr,
in addition to our standard SQ-100V vacuum motor operating to 10-7 Torr.
These motors offer precision in-vacuum alignment without mechanical
feed-throughs.

Motorized closed-loop micro stages
We incorporate our motors and position sensors into miniature
positioning stages. One of our smallest examples uses an SQL-3.4-10
SQUIGGLE motor and a Hall-effect magnetic position sensor inside the
stage body. A benefit of the Hall-effect sensor is that it acts as
an absolute position sensor: working by measuring the field along a
magnetic strip, it retains position information even after
power-down cycles. The SQUIGGLE motor is mounted onto the bottom
plate and the screw is pressed against the end of the top plate, which
is spring loaded against the screw. Used with the MC-1100
controller, this closed-loop stage has 10 microns resolution over 2
mm of travel. A high-resolution controller with 16-bit A/D converter
achieves a resolution of less than one micron.

Custom closed-loop linear positioning stage
is the smallest on
the market.
