What is an Alternator?
An alternator is what keeps your vehicle’s battery charged while it’s running. It works by converting the mechanical energy from the engine into electrical energy that can be used to power the electrical components of your vehicle. In most cars, the alternator is driven by a belt that’s connected to the engine’s crankshaft.
The alternator has two main components: the rotor and the stator. The rotor spins inside the stator, which is made up of a series of coiled wires. As the rotor spins, it creates a magnetic field that passes through the stator’s wires, generating an electrical current.
