How do PiezoWalk Motors work in Linear Nanositioning Stages?
The video explains the concept of PiezoWalk Motors in precision motion and nanopositioning applications. Walking piezomotors are use four or more piezoceramic fingers which actuate in a stepping sequence to drive a workpiece in a desired direction. Between steps, sub-nanoscale actuation can be achieved. High power-off holding forces and essentially unlimited travel characterize these designs, exemplified by PI’s NEXACT and NEXLINE technologies.
