Auburn, Mass. – PI (Physik Instrumente) introduces the new N-216 NEXLINE® high-load piezo linear motors. These highly precise nanopositioning actuators provide travel ranges to 20mm with a resolution of 0.03nm, and push/pull forces to 600N (130lbs) and holding forces to 800N (177lbs).
The piezoceramic clamping and shear elements act directly on a moving runner coupled to the load. For maximum velocity, and long distance movements, the runner can be driven in full step mode. Extremely uniform motion and constant velocity is achieved with the nanostepping mode.
The N-216 linear motors come in two versions for open- or closed-loop operation, as well as in two different load configurations. Closed-loop versions are equipped with a linear encoder for direct position measurement of the moving runner. The encoder features 5nm resolution over the full travel range.
Applications include high-end ultra-precision manufacturing and semiconductor test equipment to astronomy and high energy physics applications. Extreme reliability makes them ideal for applications in difficult-to-access internals of instruments, requiring nanometer-realm adjustment and/or vibration cancellation.
