Your BMW is full of complex and intricate
mechanisms and systems. Its engine, just like in any other vehicle,
serves as the core system of the life of your BMW car. It is the engine
that is considered as the system that controls almost all of the
systems of the automobile. Without the engine, it would be impossible
to put the vehicle in motion. However, the functions of the engine
system would not be possible without the help of another system - the
The electrical system transforms mechanical power to
electrical power and transmits it from one automotive system and
to another. The electrical system owes its power in turn from another
electrical component: the battery. The battery is the heart of the
electrical system. The same with the engine's need for gasoline to keep
its function, the battery also needs to be fed, or else its voltage
will be lost. Eventually, the system would not be able to convey its
significant participation to the entire operation of the automobile.
This is where the charging system comes into play. The charging
procedure of the electrical system of your BMW car is carried out
through the alternator. The alternator is one of the two basic
components (the other one is the voltage regulator) of the charging
system. These components work together with the battery to supply the
necessary power or current whenever your BMW car is running. The output
it actually produces is direct current as your BMW alternator is
responsible for the process of generating and delivering electrical
power to the battery and the rest of the electrical system of the car.
The alternator produces voltage and current by simply using the
principle of electromagnetic induction. The process would basically
revolve around the magnet (rotor), rotated inside a stationery looped
conductor (stator) and then a voltage is generated. It is important to
note that the strength and polarity of the voltage is dependent to
these factors: on the direction of rotation; the strength of the
magnetic field; the number of conductors; and as well as the speed of
the rotor inside the stator.
The BMW alternator assembly is the arrangement of many components. If
the charging system of your car is not working properly (intermittent
charging results) there is something wrong with this assembly.
Normally, your BMW alternator would fail to work because of the
regulator brushes located at the back of the alternator. As part of
preventive measures, you should get the system checked on a regular
basis to detect whatever the cause of the failure is.
