A machine governor is a device that regulates the speed of a machine, such as an engine. Governors can also be used to limit the top speed of vehicles and protect engines from damage due to excessive rotational speed. 

Governors typically regulate engine speed by varying the rate at which fuel is supplied. Most governors use centrifugal force and consist of two masses rotating around a spindle. 

Here are some examples of governors:
Aircraft propellers: The governor senses the shaft RPM and adjusts the angle of the blades to vary the torque load on the engine.
Centrifugal governor: Also known as watt governor, this was invented by James Watt in the 17th century to regulate the speed of steam engine by altering steam flow. 

Governors can be broadly classified into two types:
Centrifugal governors: These governors operate based on the principle of centrifugal force.
Mechanical governors: These governors operate based on the principle of centrifugal force and mechanical linkages. 

There are also other types of governors, including: Watt, Hydraulic, Pneumatic, Electronic, Digital.
