The output frequency of the
driver electronics self-adjusts
to the resonant frequency ofthe motor ceramic, so no indi-vidual tuning is necessary. Piezo Micromotor: 9 x 5.7 x 2.2 mm Velocity to 80 mm/s Notes Generated Forces up to 0.2 N The products described in this
document are in part protected
by the following patents:German Patent No. 102004059429
International Patent No. WO2006/027031A1 Self-Locking Travel Range 3.2 mm Working Principle P-652 drives employ a new,patented, ultrasonic piezomo-
tor drive developed by PI. The
highly compact, integrated
piezomotor can provide accel-erations of up to 2.5 g andvelocities of up to 80 mm/s
together with high position res-
olution and—considering its
length of only 9 mm—high
holding force. Because theceramic stator is pressedagainst the slider, piezomotor
drives resist motion with an
intrinsic holding force when
the unit is at rest. The result is
very high position stability
without the heat dissipationcommon in conventional linearmotors. During operation, the
oscillating piezoceramic moves
the slider over the length of the
motor. There are no gears,
leadscrews or other mechani-
cal components to contribute
play or backlash. P-652 PILine >
® OEM piezomotordrives are ideal for OEM appli-cations where space is limitedand moved masses are small.
These minute linear position-
ers can be used to replace clas-
sical drive elements like minia-
turized motor/spindle systemsor other
linear motors suppliers, whichP-652 outclasses with its speed
of up to 80 mm/s. The basic
advantages PILine >
® piezo linearmotors offer compared to clas-sical drives are: High velocities Compact design High push/pull and holdingforces relative to the drive
sizeThe integration of P-652 in anapplication is simple, becausethe moving slider and the piezoactuator are delivered assem-
bled as a unit. All that remains
is to provide for mounting the
stator, affixing the load to theslider and making the electrical
connections. The motors are designed formoving small objects such as
glass fibers, optical, micro- or
electro-mechanical elements
fast and precisely. >
