Engine Speed Governors | Speed Control Governor | Speed Limiters

Engine Speed Governor The engine speed governor is a device which is used to controlling the speed of an engine based on the load requirements. Basic governors sense speed and sometimes load of a prime mover and adjust the energy source to maintain the desired level. So it’s simply mentioned as a device giving automatic control (either pressure or temperature) or limitation of speed. The speed governors are control mechanisms and they work on the principle of feedback control. Their basic function is to control the speed within limits when load on the prime mover changes. They have no control
