Product Description

Universal Governor Apparatus

The equipment is designed to study various governors. The 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 and pulley system. The optional governor out of four governor assemblies can be mounted on 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 weight may be added. The Hartnell governor provides means of varying spring compression level. This enables the Hartnell governor to be operated as a stable or unstable governor.


  • Drive unit - PMDC motor, 1/6 HP, 1500 RPM
  • Speed control unit working on 230V AC supply with 0-200V DC output
  • Belt and Pulley system to give spindle speed 100 to 500 rpm.
  • Governor Mechanism with springs and weights for following Governors.
  • Watt Governor
  • Porter Governor
  • Hartnell Governor
  • Procell Governor


  • For all types of Governors.
  • Determination of characteristic curve of sleeve position against speed of spindle.
  • Derivation of actual controlling force curves from the above and comparison with theoretically predicted force curve.
  • Porter and Proell Governor - The effect of varying mass of sleeve.
  • Hartnell Governor - The effect of varying initial spring compression.
