Der Unterschied zwischen Lichtmaschine und Anlasser

The alternator turns electrical energy into mechanical energy, which allows the automobile to power up the battery while driving. The starter operates differently, transforming the vehicle’s electrical energy into mechanical energy. The starter and alternator are vital components of a car’s power system. While they both power the vehicle, they function in separate ways and play different responsibilities. This post will examine the distinctions between a starter and an alternator and how they serve.

Definition of a Starter and an Alternator

The starter is placed towards the bottom of the motor on the left side. The motor is started by a power source that revolves. The alternator is positioned in the front left of the engine and begins when the engine is turned on. The alternator regulates the energy required to power the vehicle’s various components so that they can operate.

Differences Between a Starter and an Alternator

An alternator is a piece of electrical machinery. Its purpose is to charge the battery regularly. The alternator, however, could demand a dead battery. The alternator generates the power utilized by various automobile elements, not the storm, as users commonly imagine. The starter is an electric motor mounted on the engine’s side. The machine is started by rotating the starter. The name is appropriate since the starter sounds precisely like it does.

How a Starter Works

When customers turn the key or push the engine start button, a tiny starting gear contacts the engine’s flywheel. The machine is then formed by delivering power. This permits it to pull air and fuel into the cylinders and start the combustion process, allowing it to function independently.

The Components of a Starter

A starting motor comprises numerous parts, such as a battery, a solenoid, Armature, Commutator, Plunger, Brushers, and an electric motor. As you turn the ignition key to start the engine, the starter motor solenoid contacts the starting gear with the flywheel, causing the machine to spin over.

The Mechanics of a Starter

The starting motor generates mechanical power from the battery, which is transmitted to the engine. Even in winter, the starting motor is intended to turn the engine over swiftly and effectively.

How an Alternator Works

An alternator, in conjunction with the battery, supplies electricity to the vehicle’s electrical components. An alternator’s source is direct current (DC). As the alternator gear is twisted, alternating current (AC) flows via a magnetic field and generates an electrical current. The rectifier then converts this to direct current.

The Components of an Alternator

A rotor, a stator, and a voltage regulator are the three main components of an alternator. The rotor is a revolving component that produces a magnetic field, whereas the stator is a stable part containing the electrical windings.

The Mechanics of an Alternator

The alternator generates electrical energy by converting mechanical energy from the engine, which is then utilized to activate the vehicle’s power system and replenish the battery. The rotor produces a magnetic field, creating alternating current (AC) in the stator windings, which the rectifier circuits correct into direct current (DC).

Compare a Starter and an Alternator

Although the starter and the alternator are essential parts of a car’s electrical system, they operate in distinct ways and serve separate functions.


The starter is a motor that starts the engine, whereas the alternator is a generator that generates electricity to charge the battery and operate the vehicle’s entire circuit.


The starter comprises a battery, a solenoid, and an electric motor, whereas the alternator includes a rotor, stator, and voltage regulator.


The starter’s primary duty is to get the engine to turn over to begin the vehicle. In contrast, the alternator’s primary function is to create electrical power to replenish the battery and power the car’s electrical system.


Despite being both essential components of an automobile engine, the alternator and starting motor serve distinct purposes. The alternator creates power, whereas the starting motor consumes electricity. These engine elements utilize and produce electricity, but they perform different tasks in the cycle. The starter’s primary duty is to get the engine to turn over to begin the vehicle. In contrast, the alternator’s essential task is to create electrical power to replenish the battery and power the car’s electrical system.
