® Micro Piezomotor Linear Drive
Ordering Information P-652 Miniature PILine ® OEM-Drive Different integration methods onrequest Operation with conventionalcontrollers Working Principle P-652 drives are based onPILine P-652 drives employ a new,patented, ultrasonic piezomo-tor developed by PI. The highly
compact, integrated piezomo-
tor can provide accelerations of
up to 2.5 g and velocities of up
to 80 mm/s, together with high
position resolution and—com-pared to its small size—highholding force. Because the
ceramic stator is pressed
against the sliders of the drive,
piezomotor-drives resist mo-
tion with an intrinsic holdingforce when the unit is at rest.The result is very high position
stability without the heat dissi-
pation common with conven-
tional
linear motors. Further-
more, there are no gears,
lead screws or other mechanicalcomponents to contribute playor backlash.

® piezomo-tor drives are ideal for OEM
applications where space is
limited and masses are small.The P-652 may replace classi-cal drive elements like rotary
motor/leadscrew assemblies or
other linear motors in a micro-
system. The basic advantages
PILine
® piezo linear motorsoffer compared to classical drives are High velocity Compact size Self-locking at rest without
heat dissipationThe integration of P-652 is sim-ple because the moving slidersand the
piezoceramic motorare already delivered as a unit.
Mechanical and electrical inte-
gration must be assured by the
system the P-652 operates in. The drive design was opti-mized for moving small objects
such as fibers, optomechanical
components, micromechanics
or MEMS fast and precisely.
