The Porter Governor and Instantaneous Centre Method
Porter Governor
The Porter governor is a modification of a Watt’s governor, with central load
attached to the sleeve
2. Instantaneous centre method
In this method, equilibrium of the forces acting on the
link BD are considered. The instantaneous center I
lies at the point of intersection of PB produced and a
line through D perpendicular to the spindle axis, as
shown in Fig. Taking moments about the point I,
The Porter Governor is a modification of the Watts Governor, involving a central load attached to the sleeve. The Instantaneous Centre Method analyzes the equilibrium of forces acting on the link BD by considering the instantaneous center I located at the intersection of PB produced and a line through D perpendicular to the spindle axis.
