Geneva indexing mechanism ⚙| How it works This video demonstrates the working principle of a Geneva Indexing Mechanism used in a rotary table for precise intermittent motion. The rotary table shown here has 10 indexing positions, matching the ten slots on the Geneva wheel. A driving wheel, fitted with a single indexing pin, is mounted directly to a 3-phase AC motor shaft. As the motor rotates, the pin engages each slot on the Geneva wheel, forcing it to rotate by a fixed angle per cycle. The Gen
