Isochronous governor is a governor that keeps the speed of a prime mover constant at all loads. Also known as a static governor. A governor is said to be isochronous if equilibrium speed is constant for all the radii of rotation in the working range. Therefore, for an isochronous governor the speed range is zero and this type of governor shall maintain constant speed.

Explanation:
An isochronous governor is a type of centrifugal governor that maintains a constant speed of rotation of the engine or machine it is controlling, regardless of the load or external conditions. In other words, the equilibrium speed of an isochronous governor remains constant within its working range.
Working of an Isochronous Governor:
An isochronous governor consists of two rotating balls or weights connected to a central spindle. As the speed of the engine or machine changes, the centrifugal force acting on the balls also changes. This centrifugal force is counteracted by a controlling force, usually provided by springs or weights, which adjusts the position of the balls to maintain a constant equilibrium speed.
Variable Speed for Different Radii:
If the equilibrium speed of the governor was variable for different radii of rotation of the balls, it would mean that the governor is not isochronous. In this case, the speed of the engine or machine would vary depending on the radius at which the governor balls are rotating. This would result in an inconsistent speed control, which is not desirable for many applications.
Constant Speed for All Radii:
In the case of an isochronous governor, the equilibrium speed remains constant for all radii of rotation of the balls within its working range. This means that regardless of the position or radius at which the balls are rotating, the speed of the engine or machine will be the same. This ensures a consistent and stable speed control, making it suitable for applications where a constant speed is required.
Conclusion:
In summary, an isochronous governor is one that maintains a constant equilibrium speed regardless of the load or external conditions. The equilibrium speed is constant for all radii of rotation of the governor balls within its working range. This ensures a consistent and stable speed control, making it ideal for various applications.
