PI's new line of compact ceramic piezo motors & actuators replaces classical actuators & motion control components in medical and pharmaceutical applications.  High-speed motors, high force actuators and zero-wear flexure designs are available.

Advantages: sterile, no lubricants, high speed, millisecond responsiveness, vacuum compatible, non-magnetic

Applications: Precision Motion Control, Optics & Imaging, Fast Valve Control, Applications in High Magnetic Fields, Vacuum, Liquid Dispensing, Fast Pumps, Scanning Microscopy, OCT, MRI.

PI offers three advanced types of ceramic, non-magnetic linear motor actuators that can replace classical actuators. The three types are distinguished by force, travel range and speed and precision.

* For short travel ranges (<0.5 mm), high forces and very rapid response (sub-millisecond feasible) the PiezoMove® flexure actuators are recommended.

* Basically unlimited travel ranges are provided by both the ultrasonic and piezo stepping type linear motor actuators.

* While the faster ultrasonic motor actuators provide speeds to 800 mm/sec, the piezo stepping motor actuators feature higher resolution and forces.

Non-magnetic, sterile, (bakeable to 150C) and vacuum-compatible

In contrast to servo or stepper motor actuators, the piezo ceramic linear motors effect linear motion directly, without the need to transform rotation with gears and leadscrews. Backlash and wear are eliminated and the drive is maintenance-free. Piezo ceramic actuators exhibit high stiffness and are self-locking when powered down with nanometer position stability, and zero heat dissipation or servo-dither at rest.
