Totally kewl motors... maybe good as a small actuator, replacing pneumatics or big servos. If I read the overview correctly, even the load bearing capacity of these "tiny" motors is a non-issue. This actually reminds me of Canon's USM (ultrasonic motor) technology used in lens focusing mechanisms.

If you find a price, let me know - they look like amazing little linear actuators...

$950 for a motor with controller and power supply.  Here's some additional detail from the sales department -

Quote
The Squiggle motor uses ultrasonic vibrations in a threaded nut to precisely
rotate a fine-pitch screw. The standard motor moves in increments as small
as 20 nanometers, pushes >5 Newtons, moves up to 2 millimeters per second
and holds position when powered-off.

Gordon you beat me to it . . .

So I emailed them for info and they just sent me this, mostly just repeating what Gordon said:

Thank you for requesting information about our new Squiggle motor. We
developed this tiny linear actuator to enable our customers to create
advanced research tools and highly miniaturized products.

The Squiggle motor uses ultrasonic vibrations in a threaded nut to precisely
rotate a fine-pitch screw. The standard motor moves in increments as small
as 20 nanometers, pushes >5 Newtons, moves up to 2 millimeters per second
and holds position when powered-off. This small, quiet design is perfect for
use in vacuum as well as non-magnetic applications.

The latest SQL series are our smallest Squiggle motors to date. They are a
new alternative drive solution for OEM applications with space restrictions.
Evaluation kits for these new models are available. They include an
SQL-3.4-10-xx motor (different sizes to choose from), an oem control board
with software, adapter cables & power supply. The price for a single
evaluation unit is $950. An optional handset for manual input is also
available for $250.

I welcome the opportunity to better understand your specific requirements.
The more details regarding the load, speed, travel, resolution and space,
the better we can help to determine if the Squiggle motor is a good
solution. I look forward to your e-mail reply or phone call.


Despite the motor being really tiny, it unfortunately could never be used on a microrobot because the driver is comparatively huge!
