New Brochure: Piezo Step Linear Motors for Ultra-High Precision Motion Control Applications

(Nanowerk News) PI (Physik Instrumente) L.P. – a leading manufacturer of ultra-precision motion-control and sensing equipment for bio / nanotechnology, photonics, semiconductor and life science applications – offers a new brochure on piezo ceramic linear motors.
Piezo Linear Motor Brochure
Non-Magnetic and Vacuum Compatible
These motor actuators are non-magnetic, vacuum compatible and achieve significantly higher forces and resolution than other piezo motor designs, such as ultrasonic motors or inertial motors.
PiezoWalk® Stepping Principle: High Force, Dynamics, Sub-nm Resolution
The new linear motors are based on the patented PiezoWalk® principle and achieve forces from 2 kg to 60 kg per actuator. They are available in two versions called NEXLINE® (higher force) and NEXACT® (smaller, and faster). In addition to a long-range step mode, both also provide a very high dynamics sweep / scanning mode, enabling 50 picometers of resolution and kHz range bandwidth.
Integration in Positioning Systems
These novel motor actuators are also available as drive systems in nanopositioning linear stages and multi-axis positioning systems, such as 6-axis Hexapods or tripod Z/tip/tilt platforms.
Applications Fields:
  • Optics & Photonics
  • Aerospace
  • Semiconductor Test & Measurement, Alignment
  • Precision Motion Control
  • Microscopy
