Precision-Controlled Moving Gears Mesh Seamlessly at 4,500 RPM

In this remarkable demonstration of precision machinery recorded by DigInfo TV, three servo-powered gears running at 4,500 RPM mesh seamlessly as they rotate, move, and overlap in a variety of configurations. The servo system was developed by Mitsubishi Electric and is on display at the CEATEC 2013 electronics show in Japan through October 5.
