    World's smallest linear motor

    World's smallest linear motor

    Victor, NY – May 25, 2006 – The latest SQUIGGLE motor from New Scale Technologies, Inc. is the smallest linear motor on the market, the company announced today. At 1.5 mm x 1.5 mm, the new SQL-1.5 piezoelectric motor is half the size of competing micro-motors. It also offers a 20 gram push force and sub-micron position resolution, performing ten times better than its closest competitor on both counts.


    “The SQL-1.5 opens a whole new range of performance for miniature electronic systems such as phone cameras and medical devices,” said New Scale president David Henderson. “Designers of leading edge mobile devices finally have a precise, reliable linear motor that fits within their size and power budgets. They can add motion – and hence new capabilities – where they were unable to do so before.”



    Typical applications: phone cameras and medical devices

    The SQL-1.5 has been designed into next-generation auto focus and optical zoom assemblies by leading camera module developers, who support the top tier handset manufacturers. Focus and zoom capabilities have become an essential ingredient in the drive to deliver smaller, thinner handsets with the image quality of digital still cameras.



    “Even by the most conservative handset sales forecasts, phone cameras alone represent a new market for one billion motors a year,” Henderson said. “The requirements of these cameras can not be met by current motor technologies.”



    The SQL-1.5 is also of interest to medical device manufacturers for a new class of implantable drug pumps and micro-valves. The motor itself is tiny, but its high precision is what enables the most dramatic reduction in overall device size. It provides more precise valve control, which permits more concentrated medications and therefore smaller fluid reservoirs. The patented ceramic motor design generates no magnetic fields and can be made of non-ferrous materials, making it MRI-safe and image compatible.



    SQL-1.5 SQUIGGLE Motor Specifications



    - Motor body dimensions...... 1.5 mm x 1.5 mm x 6 mm
    - Stroke..................... 10 mm (customizable)
    - Resolution................. Better than 100 nm
    - Speed (no load)............ Up to 10 mm/s
    - Force...................... > 20 grams
    - Typical input power (moving)....400 mW (< 40 V)

    SQL-1.5 SQUIGGLE motor evaluation kit is $950 and will be available to qualified OEMs for delivery in July 2006.



    The evaluation kit includes an SQL-1.5 SQUIGGLE motor, drive electronics card, cables, and computer control software including an ActiveX command library.

    First of all, I would like to thank you for this article. I wonder if there is a micromotor that can provide more than 20 grams of force. For example, is there a micromotor of the same dimensions and can provide till 100 N?

    Thank you in advance
