Basic Facts Concerning AC Generators

AC Generator

Image From Wikipedia
A single phase generator or alternator produces a single alternating current.

Basically ac generators are machines that create electrical power. Converting motorized energy into electricity. These power generating machines can be extremely useful. Especially during power failures (e.g. backup power generators).

They also provide power in places where utility power is not available (campsites, caravan parks, etc.). Furthermore power generators can also be used for all applications (residential, industrial, and commercial application).

There are various types of power generating machines these days. A AC generator is the most commonly used type of power generators.

AC Generator Differences

AC generators – more commonly known as “alternators”. Machines that generate an alternating current. This means the power or voltage that the generator produces transpose alternatively. From positive polarity to negative polarity. Thereby, creating a corresponding change in the course of the flow of its current. I know it sounds complicated.

Similar to DC generators,  AC generators require coils. These cut across the lower lines of a “magnetic field”. The coil or coils are connected to “slip rings”. These deliver the flow to and from the “load destination”.

Therefore completing the process. Halfway through the full revolution. The coil cuts across the area close to the north polarity of the magnetic field.

Electrons pass through the wire. Then the slip ring on the lower side then becomes “positively charged”.

When the coil stops in the vicinity of the south pole. Its second half revolution. Then the lower slip ring changes from positive charge to negative. This is when the electrons travel down the wire.

The faster the coil rotates, the faster the electron travels. Increasing the rate of recurrence of the current generated by the AC generator.

AC generators do have some disadvantages. The main one is that the motor must have a high level of current flowing.

Throughout the revolving contacts. This can create a lot of heat. Occasional sparks. Which loses energy and can significantly reduce the lifespan of the motor.

AC Generators Magnetic Field

Most of the turbines of AC generate magnetic field created by an “electromagnet”.

The electromagnet is powered by the same alternating current voltage. As the coils of the motor. The coils that generate the magnetic field are commonly known as “stator”.

Whereas the coils and the solid focal point of the motor that revolves are known as the “armature”.

The AC generator’s motor has magnetic fields, at the same time as the flow in the coil fluctuates.
