PI The PICMAWalk piezo linear motor uses a unique V-shaped arrangement of eight PICMA® piezo actuators, resembling a classic V8 engine, to deliver exceptional push/pull and hold forces, combined with nanometer precision. The space-proven PICMA® actuators are known for their outstanding reliability, offering 50N (11lbs) push/pull force and 60N (13lbs) dead holding force. The UHV-compatible linear motors achieve a maximum speed of 10mm/s (0.4in/s), and can accurately position loads up to 5kg (11lbs) with nanometer-level precision.

In contrast to classical electromagnetic actuators, piezo motor actuators offer the advantage of not creating a magnetic field and are not affected by magnetic or electric fields. These characteristics make it highly suitable for a wide range of applications, from e-beam lithography to MRI technology. In industrial settings where precise positioning of optics, detectors, or cameras is required, removing power to the actuators can be beneficial after the delicate positioning process is complete. With a power-off position hold performance of 60N, the N-331 actuator’s self-clamping design provides a decisive advantage.
