Ceramic Motor-Driven Linear Actuator from PI Raltron Expands
SHREWSBURY, MA — PI provides a large selection of piezo ceramic linear actuators for different size, speed, and force applications. At the top end of the force spectrum is the N-216 PiezoWalk® linear ac- tuator, a high-load, high-precision linear actuator designed for appli- cations that require many millimeters of travel, high force, and ex- tremely stable nanometer-class positioning. The N-216 provides 20 mm travel, push/pull force generation up to 600 N, and holding force up to 800 N, while still supporting ultra-fine positioning resolution. Depending on oper-

ating mode and feedback configuration, the actua- tor can achieve open-loop resolution down to 0.03 nm and closed-loop en- coder resolution of 5 nm. Its self-locking design al- lows the actuator to hold position without continu- ous power, reducing heat
generation and improving long-term position stability in sensitive systems. At the core of the N-216 is PI’s PiezoWalk ceramic motor drive
principle. Instead of using a conventional rotary motor, screw, or gear train as used in traditional linear actuators, motion is generated by coordinated piezo elements that act directly on a linear ceramic run- ner. The piezo elements clamp, shear, release, and return in a con- trolled walking sequence, producing precise incremental motion over millimeter-range travel. This design combines the long travel capa- bility of a traditional motorized actuator with the fine positioning be-
