Piezo Nano Positioning
Features and Advantages
of PILine
®
Ultrasonic
Piezomotors
L52159 Compact Size: the direct-
drive principle allows the de-
sign of ultra-compact trans-
lation stages. The M-662, for
example, provides 20 mm
travel in a 28 x 28x8mm
package.
L52159 Low Inertia, High Accelera-
tion, Speed and Resolution:
PILine
®
drives achieve veloc-
ities to 500 mm/s and accel-
erations to 5 g. They are also
very stiff, a prerequisite for
their fast step-and-settle
times on the order of a few
milliseconds and provide
resolution to 10 nm. The lack
of a leadscrew means no
lubricant flow or material
relaxation to cause submi-
cron creep. There is also no
rotational inertia to limit
acceleration and decelera-
tion.
L52159 Excellent Power-to-Weight
Ratio: PILine
®
drives are opti-
mized for high performance
in a minimum package. No
comparable drive can offer
the same combination of
acceleration, speed and pre-
cision.
L52159 Safe: The minimum inertia of
the moving platform togeth-
er with the slip clutch
effect of the drive provide
better protection of precision
fixtures / devices than lead-
screw-driven stages. Despite
the high speeds and acceler-
ations, there is a much lower
risk of pinching fingers or
other injuries than with
conventional drives. This
means users may not need
interlocks, light curtains or
other measures to keep
them safe.
L52159 Self-Locking Feature: PILine
®
drives create a braking force
when not energized without
the position shift common
with conventional mechani-
cal brakes. Other benefits of
the self-locking are the elimi-
nation of servo dither and
steady-state heat dissipa-
tion.
L52159 Vacuum Compatibility: Vacu-
um compatible versions of
PILine
®
drives are available.
L52159 Negligible EMI: PILine
®
dri-
ves do not create magnetic
fields nor are they influenced
by them, a decisive advanta-
ge in many applications.
L52159 Custom Solutions / Flexibili-
ty for OEMs: PILine
®
drives
are available in open-loop
and closed-loop translation
stages and as OEM compo-
nents. PI develops and ma-
nufactures all piezo ceramic
components in-house. This
gives us the flexibility to
provide custom motors
(size, force, environmental
conditions) for OEM and
research applications.
L52159 Quality, Lifetime, Experien-
ce: Based on PI's 4 decades
of experience with piezo
nanopositioning technolo-
gy, PILine
®
drives offer
exceptional precision and
reliability with an MTBF of
>20,000 hours. Rotating
components such as gears,
shafts and moving cables
that are prone to failure in
conventional motion sys-
tems, are not part of the
PILine
®
design.
