PI’s PICMAWalk piezo linear motor makes use of a novel V-shaped association of 8 (eight) PICMA® piezo actuators, resembling a classical V8 engine, to ship distinctive push/pull and holding forces, mixed with nanometer precision. These space-tested PICMA® actuators are identified for his or her excellent reliability, providing a push/pull pressure of 50N (11lbs) and power-off holding pressure of 60N (13lbs). The UHV-compatible linear motor can obtain a most velocity of 10mm/sec (0.4 inch/sec), and it could actually precisely place hundreds weighing as much as 5kg (11lbs) with nanometer-level precision.

In distinction to classical electromagnetic actuators, piezo motor actuators provide the benefit of not creating magnetic fields in addition to being unaffected by magnetic or electrical fields. This attribute makes them well-suited for a variety of purposes, from e-beam lithography to MRI expertise. In industrial settings the place exact positioning of optics, detectors, or cameras is required, it may be useful to eradicate energy to the actuators as soon as the effective positioning course of is accomplished. With 60N of power-off place maintain efficiency, the N-331 actuators with their self-clamping design present a decisive benefit.
