SQUIGGLE Micro Motors for OEMs

The World's Smallest Linear Motors

SQL Series SQUIGGLE Micro Motors for Mobile and Ultra-Miniature OEM Products

The tiny SQL Series SQUIGGLE micro motor offers greater power efficiency, higher reliability, and ten times better precision than electromagnetic motors. This linear motor is less than half the size of other piezo motors or micro 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.

 

With the SQUIGGLE motor design engineers can add motion features into products where they could not have been imagined before.
 

Features include:

 

  • NEW ASIC driver in a 4 x 4 mm QFN package
  • 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

Developer's Kits for OEMs

SQL micro motor developer's kits include one SQUIGGLE motor, a TRACKER position sensor (closed-loop kits only), controller board, cables, and New Scale Pathway™ Software: a flexible and sophisticated software platform that enables rapid evaluation of New Scale motors, sensors and motion systems. Point-and-click user interface and an intuitive scripting environment speed product design, system integration and performance validation.

 

Once you’ve determined that SQUIGGLE motors are right for your application we can provide motors in quantity, create customized micro motors, or design application-specific modules (including drive electronics and miniature position sensors) to fit your OEM requirements. See our custom engineering page for more information.

 

Motor Controllers

SQL-1.8 micro motors take a square wave drive signal.

 

  • NEW ASIC driver! The NSD-1202 is a dedicated piezo motor driver ASIC capable of driving two SQL Series SQUIGGLE motors from a single 2.8 to 5.5 VDC supply. Two SQL-1.8 motors can be controlled independently using a standard I²C interface. The MC-33DB driver includes this NSD-1202 ASIC along with all required passives and convenient connectors.

 

  • The MC-3300 is a full motion control system for with intuitive PC user interface for easy motor evaluation. It features a control processor and accepts position sensor input for both open-loop and closed-loop operation. It includes New Scale Pathway Software with point-and-click user interface, scripting environment and ActiveX command library.

 

SQL-3.4 micro motors take a sine wave drive signal. New Scale MC-1100 (drive card) and SQ-2300 (benchtop) controllers use a resonant amplifier to produce the required drive signals. Both include New Scale Pathway Software with point-and-click user interface, scripting environment and ActiveX command library.

For more information

The SQL Series micro motors described on this page are robust devices with smallest size and low battery power consumption.

 

  • If smallest size is not required, you might also consider the SQ-100 Series motors: slightly larger than the SQL Series, they offer higher precision and push force for instruments or research applications.
  • Learn more about the SQUIGGLE motor operating principle.
  • See our TRACKER position sensors - miniature encoders ideal for use with SQUIGGLE motors to create closed-loop motion systems with resolution to 0.5 micron
