Hartnell Governor Isochronous Speed Equations

A governor is a device which controls the speed of an engine, a motor or other machine by regulating the fuel or power supply. The controlled speed is called the 'isochronous speed'. Electronic systems are also available.

If a governor is in equilibrium at one particular speed at all radii of rotation, it is called isochronous governor. The sensitiveness of an isochronous governor is infinite, because the range of an isochronous governor is zero.
