Universal Governor Apparatus


The set-up is designed to study the working of different governors normally used to control the speed. It consists of a main spindle, mounted vertically on the base plate. This spindle is driven by a variable speed motor which is also mounted vertically on the same base plate. One governor assembly out of four can be mounted on spindle. The spindle speed is controlled by speed control unit. A graduated scale is fitted to the sleeve to measure the displacement.
