SQL-1.8-RV Series SQUIGGLE motor with NSD-2101 piezo driver - the world's smallest linear drive system. The 2.8 x 2.8 x 6 mm and 1.8 x 1.8 mm IC are powered by direct battery input as low as 2.3 VDC with no need for a boost circuit.

SQL-RV-1.8 Developer's Kits are available for qualified OEMs. Battery operated kits let OEM designers evaluate the SQL-RV-1.8 SQUIGGLE micro motor for custom development programs supported by our engineering team. Kit includes an SQL-RV-1.8 motor, optional position sensor, controller and New Scale Pathway software.

SQL-RV-1.8 SQUIGGLE RV Reduced Voltage
Linear Micro Motor and Piezo Motor Driver

The world’s smallest linear motor, with the smallest piezo driver and reduced voltage requirements, powers New Scale's M3 embedded motion modules

 Note: SQUIGGLE motors are not available for sale. New Scale's smart motion systems incorporate our SQL-RV-1.8 and NSD-2101 components. See our M3 Smart Modules or contact us about custom integrated motion solutions using these piezo motor components. 

New Scale creates small, precise and smart motion systems using our SQL-RV-1.8 SQUIGGLE® RV Reduced Voltage micro motor and NSD-2101 drive IC, integrated into custom modules that deliver performance comparable to much larger systems. This technology is the heart of our M3 micro mechatronic module design platform and many of our full-custom motion solutions. It allows us to create motion features for products where they could not have been imagined before.

This tiny linear drive system offers greater power efficiency, higher reliability, and ten times better precision than electromagnetic motors. It offers unmatched miniaturization and performance for smaller, hand-held, portable and mobile devices.

The patented, reduced voltage SQUIGGLE RV ultrasonic piezo motor features state-of-the-art multi-layer piezo technology. It delivers direct linear movement with no gears or cams, and has a self-locking design that uses power only when moving. The robust construction withstands high shock loads and offers silent, ultrasonic operation over a wide operating temperature range.

The NSD-2101 piezo motor driver converts 2.3 to 5.5 VDC battery input directly to high frequency AC power to control the SQL-RV SQUIGGLE motor. Custom designed to drive the SQUIGGLE RV multi-layer motor, the NSD-2101 provides advanced patented features such as frequency tracking and hybrid speed control to optimize motor performance while minimizing power consumption over a broad range of operating and environmental conditions. The NSD-2101 accepts commands from your system processor over a digital I2C serial interface.

System Performance

The SQL-RV-1.8 and NSD-2101 drive IC provide a broad range of performance over a range of input voltages. Refer to the tecnical bulleting for motor force and speed as a function of input voltage to the NSD-2101 driver IC, as well as the power required at various voltages to achieve a range of linear motor speeds.

Note: We don't sell SQUIGGLE motors. We develop smart motion systems using the SQL-RV-1.8 and NSD-2101 components. See our M3 Smart Modules or contact us about custom integrated motion solutions to meet your unique requirements.

New Scale Pathway Software is a flexible and sophisticated development tool for evaluation, testing and system development using New Scale micro motors and modules. (click for larger image)

Developer's Kits

Developer's Kits allow engineers to evaluate a tiny, closed loop motion system reference design with integrated SQUIGGLE RV micro motor, NSD-2101 piezo motor driver and NSE-5310 position sensor. The kits demonstrate the performance of these tiny components pre-mounted in an integrated motion system.

The kits include New Scale Pathway™ Software, a flexible and sophisticated tool for rapid evaluation of New Scale motors, sensors and motion systems. An easy-to-use, "point and click" graphical user interface allows you to select tabs, enter values in boxes (speed, step, frequency, etc.) and click graphical buttons (jog, run, etc.) to control New Scale systems. All features are accessible using mouse and keyboard. The software also features a powerful script generator that enables you to create and run automated commands and sequences for almost any motion control task. The script editor is fast, flexible and easy to use, even by non-programmers.

The developer's kit is designed to help engineers define system specifications for subsequent development of custom micro motion modules with New Scale Technologies.
