- "Welcome to our exploration of DC generators. Today, we'll dive deep into the components that make up these fascinating machines and how they work together to generate electricity."
At the core of every DC generator is the armature, a coil of wire that rotates within a magnetic field created by stationary magnets or electromagnets."
As the armature spins, it cuts through the magnetic lines of flux, inducing an electromotive force (EMF) in the coil."
This induced current flows through the armature windings and is collected by stationary contacts called brushes."
The brushes are in contact with a split-ring commutator, which consists of two segments, known as the commutator segments."
When the armature coil reaches a 90-degree angle, the change in magnetic flux induces the maximum EMF, resulting in a peak current flow."
As the armature continues to rotate to 180 degrees, the induced EMF drops to zero."
At this point, the commutator segments switch the connection of the brushes, ensuring that the current flows in one direction."
This design ensures a steady flow of direct current (DC) from the generator, which can then be used to power various devices and systems."
And there you have it, the anatomy and operation of a DC generator explained. Join us next time for more insights into the world of electrical engineering."
Parts of a DC Generator
Stator
The main function of the stator is to provide magnetic fields where the coil spins. A stator includes two magnets with opposite polarities facing each other. These magnets are located to fit in the region of the rotor.
Rotor
A rotor in a DC machine includes slotted iron laminations with slots that are stacked to shape a cylindrical armature core. The function of the lamination is to decrease the loss caused due to eddy current.
Armature Windings
Armature windings are in a closed circuit form and are connected in series to parallel to enhance the produced current sum.
Yoke
The external structure of the DC generator is known as Yoke. It is made of either cast iron or steel. It provides the necessary mechanical power for carrying the magnetic flux given through the poles.
Poles
The function of a pole is to hold the field windings. These windings are wound on poles and are either connected in series or parallel by the armature windings.
Pole Shoe
Pole shoe is mainly utilized for spreading the magnetic flux to prevent the field coil from falling.
Commutator
A commutator works like a rectifier that changes AC voltage to DC voltage within the armature winding. It is designed with a copper segment, and each copper segment is protected from the other with the help of mica sheets. It is located on the shaft of the machine.
Brushes
The electrical connections can be ensured between the commutator as well as the exterior load circuit with the help of brushes.

Where have you been for so long?
From today on words I will try to upload video every week. Thanks for your support guys.
@@creativelearning3d oh. Ur wlcm❤️
What kind of tools used to make this animation.
Can let me know
I am using so many tools to create 1 video for you guys from storyboarding to final editing. for 3d i am using 3ds max for editng I am using after effect and many more.
