Why All Piezo Motors are NOT Created Equal: The piezoelectric effect for precision motion control - PI Physik Instrumente.
phenomenon the “piezo effect”. Later, they ascertained that when exposed to an electric potential, piezoelectric materials change shape. This they named the “inverse piezo effect”. More on the fundamentals [...] mm/sec. PiezoWalk® linear motors can achieve the highest forces along with picometer resolution, however velocity is limited from 1mm/sec for high force devices and up to 15mm/second for the new V-8 PicmaWalk [...] voltage to maintain a position for a long time. Force Generation: High Speed Valves, Dispensers, Pumps One of the advantages of piezo ceramics is their high force generation and extremely fast response capabilities
