New SQUIGGLE® RV micro motion system operates directly from a 3 VDC battery for industry's lowest power consumption and smallest system size

The "Reduced Voltage" SQL-RV-1.8-6-12 piezo micro motor and NSD-2101 drive chip deliver performance comparable to much larger motion control systems, at 40% lower power and less than one-fourth the size

Victor, NY - January 12, 2010 – New Scale Technologies, Inc. announced today a breakthrough in piezo motion control system design. The SQUIGGLE RV reduced voltage linear drive system consists of a SQL-RV-1.8-6-12 SQUIGGLE motor and NSD-2101 drive ASIC. It is the industry's first miniature piezo motor drive solution with a driver chip that is smaller than the motor and driven directly from battery power as low as 2.3 VDC without the need for a voltage boost.

The SQUIGGLE RV motor is New Scale's next-generation piezo micro motor, using state-of-the-art, multi-layer piezo technology from TDK-EPC (www.epcos.com) to reduce the input voltage requirements of this tiny motor – still the world's smallest linear motor at 2.8 x 2.8 x 6 mm. The NSD-2101 driver was developed for this new motor in partnership with austriamicrosystems(www.ams.com) using advanced integrated circuit designs and patented control systems. This smart IC measures only 1.8mm x 1.8mm and drives the SQUIGGLE RV motor directly, without the need for an external boost circuit.

"This is a tremendous milestone for the piezo motor industry," states Ralph Weber, product manager at New Scale. "We are the first company to commercialize a piezoelectric motor system that matches the low voltage operation of stepper motors while at the same time using radically less space and power."

The SQUIGGLE RV linear drive system is more than five times smaller and uses 40% less power than comparable electromagnetic linear drive systems.

The NSD-2101 accepts direct 2.3 VDC to 5.5 VDC battery power and uses patented full-bridge switching technology to create the ultrasonic motor drive frequency. The IC also has patent-pending smart drive features built in that optimize motor performance while minimizing power consumption over a broad range of operating and environmental conditions. The NSD-2101 requires only DC battery power and digital I2C control commands to achieve unrivaled miniature motion control performance.

The SQL-RV-1.8 motor achieves forces in excess of 50 grams and high resolution to 0.5 micrometer. It can run at speeds greater than 7 mm/sec with power consumption of less than 350 mW when moving under typical loading conditions. This corresponds to a DC current of only 120 mA for a typical 3 VDC battery. Its unique self-locking design means that zero power is needed to hold the motor position, providing additional power savings.

New Scale's NSE-5310 linear encoder, the world's smallest linear position sensor, can be integrated with the SQUIGGLE RV system for high system repeatability with submicron resolution.

The reduced voltage SQUIGGLE RV micro motor is ideal where high precision, miniature size and low power consumption are a must. These include medical, security, optical and imaging systems; consumer electronics; precision biomedical actuators; and miniature actuation for aerospace and industrial applications. Its small size makes it ideal for creating tiny, high resolution integrated closed-loop motion systems.

New Scale's DK-RV-1.8 series developer kits include all hardware as well as New Scale Pathway™ development software with scripting capabilities in a convenient, plug-and-play reference design for prototype development and integration. Open-loop developer's kits contain an SQL-RV-1.8 micro motor and NSD-2101 driver; closed-loop kits also include a New Scale TRACKER™ NSE-5310 linear encoder.
