Pro-Lite supplies advanced nanopositioning motion systems, sub-system modules and piezo motor/drive components from Nanomotion and from piezosystem Jena (PSJ). In photonics motion control applications, how do you combine speed with nanometric precision and unlimited travel? These seemingly conflicting requirements are uniquely addressed by Nanomotion’s ultrasonic, standing-wave, direct-drive piezoelectric motors. This technology provides unlimited linear or rotary motion of a ceramic tip that transfers drive to a target, operating in a manner similar to a DC servo motor but with much higher resolution, an order-of-magnitude higher speed and a wider dynamic range. In comparison, PSJ’s piezoelectric actuators use stacked ceramic disks which stretch and compress when a voltage is applied across the electrodes. This creates a high dynamic force capable of sub nanometer resolution over a travel range of micrometers.
