Why Porter Governor Cannot Be Isochronous?

Explanation: For a porter governor it is impossible to have the two balls moving at the same speed, thus the range cannot be 0 which makes it impossible to be an isochronous governor. Since sensitiveness is 0, therefore range is 0 hence the governor cannot be porter.

Can a porter governor be isochronous?

A Porter governor can not be isochronous. Explanation: In general, the greater the lift of the sleeve corresponding to a given fractional change in speed, the greater is the sensitiveness of the governor.

Which governor can be made isochronous?

A governor is said to be isochronous when the equilibrium speed is constant (i.e. range of speed is zero) for all radii of rotation of the balls within the working range, neglecting friction. The isochronism is the stage of infinite sensitivity. A spring-loaded governor can only possibly be an Isochronous governor.
