Novel Piezoelectric Linear Actuator / Micro-Manipulator Replaces Motorized Actuators
The N-380 NEXACT® piezo linear motor actuator shown with the E-861 piezo walk motor controller
Features and Advantages
* 1 kg Push/Pull Force, 30 mm Travel, 10 mm/sec Speed
* Self-Locking, Stiff Design; convenient ½” front mount or clamp mount.
* Stepping Mode + Sweep Mode, Millisecond Response & High Bandwidth
* Non-Magnetic and Vacuum-Compatible Options
Typical Applications:
Micromanipulation & Nanomanipulation, Nanotechnology, Microscopy & Optics, Nano-Imprint, Laser Tuning, Semiconductor Test & Production Equipment, Bio-Technology, Medical Technology.
Piezo-Class Resolution, Low Power Consumption, Long Travel Range
NEXACT® actuators provide piezo-class resolution (far below one nanometer) and millisecond responsiveness. In contrast to conventional piezo actuators, the new stepping technology allows virtually unlimited travel ranges while retaining the high stiffness, in a very small package. The special drive design reduces the operating voltage to 40 V or less, with minimal power consumption.
Very High Stability, Self-Locking, No Wear & Maintenance, No Lubricants
In contrast to DC servo or stepper motor actuators, the piezo walk drive effects linear motion directly, without the need to transform rotation with gears and leadscrews. Backlash and wear are eliminated and the drive is maintenance-free. NEXACT® actuators exhibit high stiffness and are self-locking when powered down with nanometer position stability, and zero heat dissipation or servo-dither at rest.
Working Principle: Piezoceramic Bending Elements Drive a Ceramic Runner
In operation, piezoceramic bending elements act on the ceramic runner, connected to the moving tip of the actuator. For long distance motion, the stepping mode is used. For smaller distances & for ultra-high dynamic motion, the analog (sweep) mode can be employed.
Control Electronics / Software
The actuator can be controlled through USB, RS-232 as well as with a joystick. The controller comes with a variety of software drivers and programming examples.
Proven, Award Winning Technology
N-380 series piezo walk actuators are closely related to PI’s award winning, NEXLINE® linear actuator family, the NEXACT® actuators’ big brothers.
