What Is DC Generator
An electric generator is a machine that converts mechanical energy (or power) into electrical power (or power).
Energy conversion kinetic (or kinetic) induced e.m.f. Is based on the principle of production.
When the conductor cuts the magnetic flux, the dynamically induced e.m.f. It is produced on the basis of the laws of electromagnetic induction of faraway. This.m.f. If a carrier circuit is closed then a current flows.

Construction Of A DC Machine:
A DC generator can be used as a DC motor without any construction changes and vice versa. Therefore, a DC generator or DC-DC can be broadly referred to as a DC machine.
These basic construction details are also valid for manufacturing DC motors. Therefore, let’s call this point a DC device build as a ‘DC generator build’.
The diagram above shows the construction details of a typical PO-pole DC machine. A DC machine has two basic parts; The stator and rotor basic construction parts of a DC machine are described below.
As soon as the loop is closed, there will be a current circuit through the loop. The direction of the current can be determined from Fleming’s right-hand rule.
This rule states that if you rotate your right-hand thumb, index finger and median towards each other, the thumb represents the direction of the conductor, the index finger indicates the direction of the magnetic field, N, the pole to S – Conducts pole and middle finger through conductor. Indicates direction.
Working Principle of DC Generator
The working principle of a DC generator is based on Faraday’s law of electromagnetic induction. When the conductor is located in an unstable magnetic field, an electromotive force is induced inside the conductor.
The induced e.m.f magnitude can be measured from the generator’s equation of the electromotive force.
If the conductor is present along a closed lane, the current that is induced will flow into the lane.
In this generator, the field coil converts an electromagnetic field as well as the armature conductor into a field.
Therefore, an electromagnetically induced electromotive force (e.m.f) will be generated inside the armature conductor.
The path of the induced current will be provided by Fleming’s right-hand rule.
We can see that the current always flows with ABLMCD in the first half of the revolution, that is, brush number 2 in contact with part 1.
In the other half-revolution, in the diagram, the direction of induced current in the coil is reversed. But at the same time, the positions of sections A and B are also reversed, giving the result that brush number 3 is in contact with the section.
Therefore, the flow at the load resistance again flows from L to M. The waveform of the flow through the load circuit is shown in the figure. This stream is directionless.
