Hunting occurs when the rotor position is ahead or behind the normal position. In mainly occurs in alternators driven by reciprocating engines, where the torque of rotation varies periodically; due to action of one power stroke per cycle. This pulsating driving force moves the shaft position out of normal position periodically as it rotates and this action is called hunting.
Hello…as per my view in the process of hunting when a Synchronous generator (alternator) is subjected to a sudden change in load (in the stator) causes the rotor to hunt for a new equilibrium position (let us take the example of a pendulum when its made to oscillate with a general push it oscillate with a particular amplitude and frequency and after its oscillation, reaches the mean position.
