Motorised Governor Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-TOMLE-10009
Jlab Export is a leading Motorised Governor Apparatus Manufacturer,and suppliers in India
A governor apparatus shows how a centrifugal governor responds to speed. In this motorised unit an electric motor turns the governor spindle. As the speed rises, the rotating governor balls move outward and lift the sleeve. Students measure that lift at a series of speeds and draw the characteristic curve of the governor.

Governor Experiments in the Lab
The standard practical raises the spindle speed in steps and records the sleeve lift at each step. Speed is read with a Stroboscope, which measures rotation without touching the spindle. A graph of sleeve lift against speed shows where the sleeve starts to rise and the speed range over which the governor works.
From the curve, students judge sensitivity and stability. On a stable governor the curve keeps climbing, so each speed matches only one sleeve height. A governor made too sensitive becomes unstable and hunts. For Porter, Proell and Hartnell tests on one spindle, the Universal Governor Apparatus takes interchangeable governor mechanisms.
Frequently Asked Questions
What does a governor do?
A governor controls the mean speed of an engine as the load changes. When the speed rises, its balls move outward and lift the sleeve, and on an engine that movement cuts the fuel or steam supply. When the speed falls, the sleeve drops and the supply opens up.
How is a governor different from a flywheel?
A flywheel smooths the speed changes within each cycle by storing and giving back energy. A governor controls the mean speed over many cycles by adjusting the supply as the load changes. Many engines have both.
What is hunting in a governor?
Hunting is a steady swing of engine speed above and below its mean value. It comes from a governor that is too sensitive. A small speed change throws the sleeve to one end of its travel, so the supply is overcorrected and the speed swings back. An isochronous governor is the extreme case.
How should readings be taken during the test?
Raise the speed in small steps, let the sleeve settle at each one, and record speed and sleeve lift together. Then repeat the readings with falling speed. The gap between the rising and falling curves shows the effect of friction in the mechanism.
