INTRODUCTION:
A device that converts mechanical energy into DC electrical energy is known as a DC generator. First, we have talked about how a DC generator is made and put together so that you can understand how it works.Let us first understand the construction of a DC generator
STATOR MAGNETS:
They are essentially electromagnets with an arrangement such that adjacent poles have opposite polarities. They perform the function of generating a magnetic field.
ARMATURE :
It is a system of conductors or coil that are free to rotate on the supported bearings. The armature consists of various parts; We will take each part one by one.To start with, we have armature core, it is made up of high permeability thin silicon content steel laminations. And the outer of the core has slots to carry armature windings.
ARMATURE WINDINGS:
It is generally made up of copper wires and is wound over the Armature core.
COMMUTATORS:
Copper makes up the commutator, which has a cylinder shape and performs two fundamental functions. One being, collecting the current from the armature conductor and the other being, converting the armature alternating current into a unidirectional current in the external circuit the help of brushes.
BRUSHES:
They are usually made of carbon or graphite and the main function of brushes is to collect current from moving commutator.
SHAFT:
Shaft is a rotating part of DC motor.The shaft provides us with mechanical energy as our final output. The Armature is mounted over the shaft. The DC generator's assembly will now be shown to us. We can now see how this generator is put together in the animation.
Applications:
Batteries are charged, lighting is provided, and alternators are excited by these generators. In DC locomotives, they are utilized to supply field excitation current for regenerative braking. When speed control is required, they are utilized in DC motors.
