Victor, NY - Feb. 19, 2008 - New Scale
Technologies, Inc. has added a smaller,
lower-power module to its SQL-M line of SQUIGGLE® micro-actuators.
The new SQL-M-1.8 micro-actuator module measures 13.5 x 4.3 x 4.2
mm and uses approximately 300 mW when moving. It is self-locking and
uses zero power to hold its position.
This new module is about 35% smaller than the company’s original
SQL-M-3.4 model. It also has significantly greater power efficiency,
higher speed, and longer lifetime (more than 500,000 cycles).
It is less than half the size of solenoids or stepper motors, draws
less power, and offers longer stroke with comparable force.
SQL-M Series SQUIGGLE micro-actuator modules can replace solenoids,
stepper motors and DC motors in applications where smallest size and
lowest power draw are needed. Each module incorporates a patented
piezoelectric SQUIGGLE motor - the world’s smallest linear motor –
with optical limit switches in a compact polymer housing.
Flex circuits connect the module to a miniature drive card, which
can be powered by a 3 V battery and controlled using TTL signals.
Motor driver ASICs under development with austriamicrosystems will
allow the entire motor drive circuit to fit in a 10 x 10 mm
footprint.

About New Scale Technologies
New Scale Technologies (www.newscaletech.com) creates disruptively small
motion systems based on our patented piezoelectric SQUIGGLE® motor, the world’s
smallest linear motor. This ultrasonic motor is smaller, more precise, less
expensive, more robust and more power-efficient than other micro motors. We
create complete motion systems integrating SQUIGGLE motor technology with
supporting electronics (ASICs) developed in partnership with austriamicrosystems (www.austriamicrosystems.com).
New Scale’s micro motors and micro-actuator modules enable design engineers
to create smaller products including mobile phone cameras, electronic locks and
intelligent fasteners, nano-scale fluid control including lab-on-a-chip systems,
medical devices including miniature drug pumps and endoscopes, optics and
imaging systems, automotive modules, lasers, aerospace and defense systems,
cryogenic and MRI-compatible instruments, and consumer electronics including
micro fuel cells.
