Miniature OEM Motors
The World's Smallest Linear Motors for OEM Products
Tiny piezoelectric
SQUIGGLE motors enable smaller OEM products, from consumer electronics to laboratory instruments. Their simple
construction and higher power efficiency at small sizes make SQUIGGLE motors superior to conventional
micro motors
or other piezo motors for
these applications. Features include:
- Scalability to millimeters in size
- Simple construction (7 parts) facilitates high-volume,
low-cost manufacturing
- Direct linear movement (no gears or cams) reduces part count
in OEM product
- Highly efficient piezoelectric actuators use power only when
moving
- Robust construction withstands high shock loads
- Sub-micrometer precision
- Silent, ultrasonic operation
- Wide operating temperature range
- Customizable for OEMs
- Vacuum and cryogenic versions available
The SQL Series
motor is a robust micro motor with
smallest size and low battery power consumption. It is designed for for next-generation
portable electronics, medical devices, electronic locks and
intelligent fasteners.
The SQ-100-N Series
motor, slightly larger than the SQL Series, offers higher precision and push force.
It is designed for use in OEM instruments.
SQL Series SQUIGGLE Motors for Mobile and Ultra-Miniature Products
The tiny SQL Series SQUIGGLE motor offers greater power efficiency,
higher reliability, and ten times better precision than
electromagnetic motors. It is less than half the size of other piezo
motors. It consists of seven parts in a simple,
elegant design that can be produced at low unit cost in high
volumes. This patented ultrasonic motor withstands high shock and offers millimeters of stroke.
New Scale designs and builds SQL Series motors in a wide range of
styles and sizes. Standard evaluation models for OEMs are available
now in 1.5 mm, 1.8 mm, and 6.8 mm standard body sizes.
Our engineering team will customize an SQL Series motor for your
specific application. We work with you on mechanical and electrical
integration into your system design, or we can help you create
application-specific motor modules incorporating housing, drivers
and position sensors.

SQ-100-N Series Motor for OEM Instruments
The SQ-100-N Series SQUIGGLE motor offers higher resolution and push force than the smaller SQL Series motor.
It is designed for easy integration into compact OEM instruments, including laser systems, microscopes, and other
scientific instruments.
The SQ-100-N drives axial loads of greater than 5 Newtons with 20 nm resolution. Like all SQUIGGLE motors, it
generates no magnetic fields in operation and holds position with the power off.
SQ-100-N motors have a 7.4 mm diameter with travel range to 50 mm. Vacuum and
non-magnetic models are available.

Motor Controllers
The SQL-1.5 and SQL-1.8 micro motor takes a square wave drive signal. The MC-3000
motor controller provides for easy motor evaluation in both
open-loop and closed-loop operation. It also serves as a reference
design for system integration. A PC user interface and ActiveX
command library are included.
The SQL-2.4 and SQL-3.4 motors take a sine wave drive signal. They can be driven by the MC-1000 drive card, which is suitable for evaluation purposes as well as for integration into OEM instruments.
A PC user interface and ActiveX command library are included. The SQ-2300 benchtop controller can also be used for evaluation. Both include a resonant amplifier and produce a sine wave output.
Ask for the application note “SQL Series SQUIGGLE Motor Drive Requirements” for more information on driving the SQL Series motors.

Evaluation Kits for OEMs
New Scale offers motor evaluation kits for product developers. Kits typically include one SQUIGGLE motor,
an MC-1000 or MC-3000 motor controller, AC power adapter, cables, and software for computer control. An optional
manual control handset is available.
Once you’ve determined that SQUIGGLE motors are right for your application, we can customize an OEM motor design
or application-specific module to
fit nearly any application and operating requirement.
Call us today to discuss your ideas.
