What's The Difference Between A Car Starter And A Alternator?

There are two key components in car electricity, one is the alternator, which is responsible for the power supply of the car; The other is the starter, which is responsible for starting the car. The motors of these two parts are composed of magnetic fields, armatures and rectifier components, but their functions are different, so their construction is also very different:
First, let's look at the alternator. A alternator is a device that converts mechanical energy into electrical energy. It uses the rotation of a car engine to create a magnetic field, which then generates an electric current through an armature coil.
This current is processed by the rectifier element and converted into the direct current required by the car to power the electronic equipment and systems of the car.
The alternator is usually mounted under the bonnet of the car and connected to the crankshaft of the engine by a belt, generating electricity as the engine turns.
Next is the starter. A starter is a device that converts electrical energy into mechanical energy. It creates a magnetic field through the flow of electric current, which interacts with the armature coil of the starter to create a mechanical force that drives the car's engine to turn.
The starter is usually installed under the bonnet of the car and is connected to the car's battery by a cable. When the car is started, the battery provides an electric current to the starter, which turns the engine and makes it start working.
