PI’s patented P-653 piezo motor linear slide is significantly smaller than other miniature
linear stages and provides significantly higher velocities and
resolution. This true linear motor system (no conversion of rotation)
consists of only 4 parts and can replace classical drive elements like
miniaturized motor/lead screw systems or other linear motors, which
P-653 outclasses with its speed of up to 200 mm/sec (8”/sec)
and auto-locking feature.
P-653 piezo motor linear slide
Measuring only 8.0mm in length, the new P-653 stage offers a
travel range of 2mm and sub-micron resolution, combined with a high
holding force of 0.15 N (0.5 oz) -- state-of-the-art figures for a
stage of these minute dimensions.
Easy Integration
Integration
of the P-653 in an application is simple because the moving slider and
the piezo motor are delivered assembled as a unit and already mounted
on a PCB driver board requiring only 5 VDC supply voltage.
Typical Applications
P-653-series PILine® piezoelectric ultrasonic motor
drives are ideal for OEM applications where quantities are high and
space is at a premium. The systems were optimized for moving small
objects such as optical fibers, micro-optics, or
micro-electro-mechanical elements fast and precisely. These
non-magnetic ceramic motors (no lubricants!) can also be used in
medical applications.
Features &
Advantages of the Ceramic Miniature Motors
n True
Linear Motor Slide / No Rotary Conversion Losses
n Fast: Velocity up
to 200 mm/s, Millisecond Responsiveness
n Self Locking;
Smaller, Faster, Fewer Components than Conventional Motors
n Travel Range 2 mm,
Force Generation to 0.15 N
n Cost-Effective OEM
Drive for High Quantity-Applications
n Preassembled and
Mounted on a PCB Board
n Very Compact:
Piezomotor Drive is Only 8 mm Long
Simple Control
Motion is controlled by TTL voltage pulses applied to the
driver electronics. The self adjusting driver creates the
high-frequency, nanometer level oscillations (~500 kHz) that make the
ultrasonic ceramic motor move.
Working Principle of
PILine® Piezo Ceramic Linear Motors
PILine® linear piezomotors are based on a, patented
ultrasonic drive. At the heart of the system is a rectangular
monolithic piezoceramic plate (the stator), segmented on one side by
two electrodes. Depending on the desired direction of motion, the left
or right electrode of the piezoceramic plate is excited to produce
high-frequency eigenmode oscillations of hundreds of kilohertz.
PILine® motors are vacuum compatible, non-magnetic and
self-locking.
