The patented PILIne® ultrasonic linear servo drives consist of a piezoelectric oscillator made from a rectangular piezoelectric plate. The right or left electrode of the piezo ceramic plate is excited to produce highfrequency (eigenmode) oscillations. An alumina pusher attached to the piezoceramic plate moves along an inclined linear path at the resonant frequency. In addition to resonant piezo servo motors, PI also offers the patented NEXLINE® PiezoWalk® nanodrives. These long-travel nanopositioning motors are more complex but can achieve even higher resolution, forces and—over small distances—dynamic performance.
