A 6.5N Linear Piezo Motor that is extremely compact, weighing only 16 grams. It has true direct drive with no backlash and can microstep in the sub-nanometer range. It is available with or without built-in encoder (e.g., 1.25 µm or 80 nm) and/or guiding. Full force 6.5 Newton power-off locking safety function.
A version of the motor compatible with environments with strong magnetic fields and vaccuum is also available.
The Piezo LEGS® linear 6.5N LL06 motor
Compact size for small spaces
Without the ceramic driving rod the motor can fit within a 24 mm long x 20 mm tall x 11 mm (17x20x7mm without encoder and guide) wide space. The ceramic driving rod length is the only variable. It’s length depends on your stroke requirement.
Encoder scale adhered to side of rod in close range of reader head conveniently provides accurate positional data.
The 6.5N Linear Piezo Motor is very compact.
Stroke range
| Stroke (mm) With one adaptor | Drive rod length (mm) |
|---|---|
| 0-3.1 | 30 (not available with encoder) |
| 0-13.1 | 40 |
| 0-23.1 | 50 |
| 0-33.1 | 60 |
| 0-74,.1 | 100.8 |
Motor Speed at 20ºC, No Load
| Waveform | Max Freq. (Hz) | Speed Range (mm/s) |
|---|---|---|
| Rhomb | 3000 | 0-24 |
| Delta | 3000 | 0-15 |
Motor Performance
Motor performance with waveform Rhomb (filled and waveform Delta (dotted). The full step length is the average distance the drive rod moves when the legs take one full step (i.e. for one waveform cycle).
Note: A standard deviation σ of 0.5 μm should be taken into account.
Typical values are given for 20ºC.

Piezo LEGS®motor technology
Piezo LEGS® work with friction drive, where force is created by the internal preload of the piezoceramic actuator legs in direct friction contact with the drive rod. When the legs start walking, they are always in mechanical contact with the drive rod.
Applications where LL06 is used
The 6.5N Linear Piezo Motor LL06 is excellent for tiny highly accurate motion requirements. One example is the M Dialysis micro dialysis machine. The motors are also found in e.g Semiconductor Processing Equipment, Nanometer Positioning Systems, Advanced Optic Applications, Active Autofocus Systems and Surgical Robots.
