Hello friends, in today’s article we will see what a DC generator is and how many types it has.
What is a DC Generator?
As we know, the DC generator is a machine that converts mechanical energy into electrical energy. Nowadays, its use has become very less, but in some places, it is still used.
Such as Haji is used in Battery Charging, Electroplating, Labs, etc. Thus the construction of the dc generator of dc motor is the same but the working principle of both is different.
Where a DC motor converts DC current into mechanical energy, a DC generator converts mechanical energy into dc electrical energy. There are 2 types of windings of any generator, one is field winding and the other is armature winding.
Types of DC Generators:
There are mainly 3 types of this which are as follows
DC Series Generator.
DC Shunt Generator.
DC Compound Generator.
DC Series Generator:
The DC Series Generator is used in places where there is a constant load as this generator depends on the current load. As the generator load increases, so does the output current. That is why this generator is used on constant load.
Just like a DC motor has 2 windings, this DC generator also has 2 windings. Field winding and armature winding. The field winding in this generator is combined in series with the armature winding.
Due to which an equal current flows in field winding and armature winding. The DC generator uses thick wire in the field winding. Due to which the field barrier is reduced.
Before turning on this generator it is important to note that all loads running through the edges must be on. If the pamper is in the closed position, this generator will not start. The DC generator is used as a booster in the distribution system.
DC Shunt Generator:
DC Shunt Generator also has 2 types of windings, one is field winding and the other is armature winding. In this generator, field winding and armature winding are connected in parallel. This involves the use of thin wire in the field winding which results in an increase in the windings of the winding and also increases the resistance to the generator. And thus an additional resistance is added to the field winding which is in series which helps in controlling both the current and flux of the field winding.
Thus field winding and obstruction are both parallel to the armature. The cost of such generators is low. And the size is also small. In terms of maintenance, there is less work in this. And the voltage of this can be easily reduced. But it is not possible in this generator to start with a load like DC Series Generator.
DC Compound Generator
There are 3 types of windings in the DC Compound Generator: Series field winding, Shunt field winding, and armature winding. And in winding the loops are also reduced while in shunt field winding thin wire is used which also increases the barrier and also increases the loops in the winding.
There are 2 main parts of the DC Compound Generator
1 short shunt compound generator.
2. Long shunt compound generator.
