What does an alternator regulator do and how does it work? An alternator regulator supplies current to the rotating part of the alternator. The rotating part is called the rotor, and when current is applied to it it becomes an electromagnet. Its rotation generates an alternating current in the fixed windings of the alternator, called the stator. The regulator acts as a control mechanism for this process
