How an Alternator Works

Model: (Various brands) Various
Part: Alternator

The alternator is a rotating electrical device based on the law of electromagnetic induction. The electromagnetic conversion of energy reaches 90%, which is why alternators are used as the main means of energy conversion for powering the electrical system. The alternator is located on the side of the engine block, and motion is transmitted to various components, including the alternator, via a belt. The video illustrates the various internal components of the device. Two fundamental components are the stator (the fixed component) containing a series of electrical windings that generate alternating current, and the rotor (which is mobile). The video also explains the physical law of electromagnetic induction for your personal instruction.
