CEDRAT Group, European partner of Newscale Technologies, distributes the patented TMSquiggle piezoelectric motors in Europe.
Patented piezoelectric micro motor has smallest size, high force and speed
The SQUIGGLE motor is a revolutionary linear micro motor that sets new benchmarks for small size and big performance. This patented ultrasonic motor creates high force and speed with only a few parts. It replaces complex electromagnetic gearhead motors which have hundreds of parts.
This simple, robust piezo motor is scalable to much smaller sizes than electromagnetic motors, without significant loss of power efficiency. This makes it ideal for portable consumer products such as mobile phone cameras and wearable medical devices.
This ultrasonic piezo motor technology displays the following main features:
Precise: sub-micrometer resolution
Fast: variable speed from 1 µm/second to 10 mm/second
Strong: 5 Newton force
Tiny: as small as 1.5 x 1.5 x 6 mm
Quiet and smooth
Non-magnetic
Vacuum compatible
Piezo Stepping Linear Motors for Nanopositioning and PicoPositioning and High-Speed Ultrasonic Piezo Motors for Automation:
PI provides two types of piezo linear motors: PILine® ultrasonic motors, also referred to as resonant motors, and NEXLINE® PiezoWalk® motors. Both can, in principle, attain unlimited travel, yet they are very different in their design, specifications and performance.
PILine® resonant motors are characterized by a simple design and high speed to 800 mm/s.
NEXLINE® & NEXACT® stepping motors are more complex but can achieve much higher resolution, forces and dynamic performance (analog mode).
A great advantage of piezo motors is their intrinsic steady-state auto-locking capability. It does away with servo dither and the accompanying heat generation, an undesirable feature of electromagnetic linear motors. Step and continuous piezo motors are in principle nonmagnetic and vacuum-compatible, a requirement for many applications in the semiconductor industry.

PILine® - Ultimate Motion in the Smallest Package:
PILine® M-661- and M-662-series piezo motor linear slides are the smallest high-speed piezo-motor-driven translation stages currently available on the market.
Working Principle:
M-661 and M-662 linear stages have a new, patented, ultrasonic drive developed by PI. The highly compact, integrated P-661 piezomotor drive can provide accelerations of up to 20 g and velocities of 500 mm/s and more, together with high resolution and holding force. Because the ceramic stator is pressed against a slider of the stage, piezomotors resist motion with an intrinsic holding force when the stage is at rest. The result is very high position stability without the heat dissipation common with conventional linear motors. Furthermore, there are no gears, leadscrews or other mechanical components to contribute play or backlash.
