The unit is designed to study various governors, normally used to control the speed. The unit consists of a main spindle driven by a variable speed motor mounted on a base plate. The spindle is driven by belt & pully system. The optional governor out of four governor assemblies can be mounted on a spindle. The spindle speed can be controlled by speed control unit provided. A graduated scale is provided to measure the displacement of sleeve.
The centre sleeve of portal and proell governors incorporates a weight sleeve to which weights may be added. The Hartnell governor provides means of varying spring compression level. This unables the Hartnell Governor to be operated as a stable or unstable governor.
The governor speed is increased in steps to give suitable sleeve movements possible. The speeds and displacements are recorded. The results may be plotted as curves of speed against displacements. Further tests are carried out by changing variables.
