PiezoWalk linear motor actuators are non-resonant type piezo motors and can provide very high resolution and high forces. PI currently offers two types: A smaller, faster one (NEXACT)that is based on a monolithic piezo element and a larger type consisting of several individual piezo actuators (NEXLINE). Both types generate motion through succession of coordinated clamp/ unclamp and expand/contract cycles. Each cycle can provide a steps from a few nanometers to a few microns of linear motion. With repetition rates of up to 100's of steps per second, continuous motion up to 10 mm/sec can be achieved.

These motors also provide a second, highly dynamic, analog operating mode with total travel of a few microns but picometer resolution. Another advantage of PiezoWalk motors is the autolocking feature. When at rest, they hold position with extreme stability, and no heat generation.


N-216 High-Force PiezoWalk OEM Ceramic Linear Motor Actuator

Holding Force to 800 N (176 lbs) Patented NEXLINE Piezo Walk Motor design For high-end Nanopositioning and Alignment Applications with Extreme Precision and Lifetime Requirements 20 mm Positioning range To 30 Picometer Resolution Self Locking at Rest with High Holding Force Non-Magnetic and Vacuum-Compatible Working Principle Cleanroom Compatible The N-216 linear actuators provides even higher forces than the N-111 version. It is designed for high-end nanopositioning and alignment applications with very high forces and extreme precision and lifetime requirements. The patented operating principle is based on coordinated motion of a number of highly preloaded linear and shear piezo elements acting on a ceramic runner. The net effect is the combination of piezo-class precision with travel ranges common to conventional linear motors. PDF Brochure \| High Force Piezo Motor Linear Acuator: Specs and Data
