AC Generator DC Generator & Electric Motor

AC Generator
The major parts of an AC generator are armature coil, field magnet, slip rings, brushes etc. The magnet, which produces magnetic flux in generator, is called field magnet. The direction of flux lines is from North Pole of the field magnet to South Pole.
An armature is a coil at which insulated conducting wire is wound over a laminated soft iron core. The slip rings are circular rings; fused to the ends of the coil. They rotate about the same axis as that of the armature. Brush is an arrangement that is always in contact with slip rings. Current flows to the external circuit through this.
Armature coil rotates continuously using mechanical energy. Simultaneously armature coil deflects the magnetic flux lines and emf is generated in the coil. This continuous motion of the armature coil helps to keep a constant current in the external circuit.
Let’s see the different steps in one complete rotation of the armature coil.
When the armature coil starts rotation, the angle between the axis of the coil and direction of flux be 00.There is no emf is induced in it because of no flux change. After that, the rotation of the armature coil cuts more flux lines and due to this the angle between the axis of the coil and flux becomes 900.Then maximum emf is induced in it. When the coil turns to 1800 with the flux lines, then also the emf becomes zero. When the angle turns from 1800 to 2700 then the direction of flux change become opposite, so the maximum emf is produced in opposite direction. When the coil turns from 2700 to 3600 ,the rate of flux changes reduced to zero and thus emf.
The number of cycles in one second is called the frequency of AC. The unit of frequency is hertz. The frequency of AC used in our house is 50Hz.
DC Generators
As in AC generator, the dc generator also has a field magnet and an armature coil. In dc generators the slip rings are replaced by split rings. In dc generators also, the emf induced by the armature coil is AC in nature. This emf is converted into DC using split ring commutator. The current flows to the external circuit through the graphite brush, is unidirectional.
Let’s see the difference between the emf from a dc generator and a battery.
The emf from battery is of constant intensity and without any fluctuations. But the emf from the dc source is pulsating.

Animation and the clarity of voice was helpful 🌟

[borisbecker]

Why on some other explanations is the stator to be coiled and not just a permanent magnet? The wires go through it and make it polarised. Thanks

[devadarshan]

Nice and easy way of understanding sir

[Nmjfilm]

Could I use like 10 seconds of this video for a training video I am working on for a client if you dont mind? Great work!! I can give you credit

[jilukidsworld]

Well nice animation and nice explanation
Lot of thanks

[JessicaBallie-Whye]

Thank you for the video, My only issues would be that there are no arrows on your magnetic fields lines :(

[reginaldmcnab]

A lot of information clearly and in a few words!

[samanthakaitlynmatibag]

Thank you very much it's big help for me. Thank you!!!

[chandbasha]

This is really very good sir Thanks you so much sir

[garimasinghal]

I have a doubt, How the movement of motor be ensured when The plane of the coil is perpendicular
Because The force on left arm is upward and right arm is downward, Equal and opposite
Then, How it produces movement

[marufhossainsami]

So much impressive! Its helped me a lot!

[sharrybhai]

Superb ExplanaTi0n Sir.Thnk y0u s0 MuCh❤❤❤👌👌👌

[anujashaha]

Wow, Thanks for a good explanation🤓🤓🤓

[dileepkumarvaishnav]

Thanksgiving's you to give short videos of definations

[mathdna]

excuse me, but i think in 3:34 the electric current flows in wrong direction. cmiiw

I called several magnet Mfg's and none could provide the "B" field . Interesting, Anyway I'm sure you know how to build your own "V" magnets. You don't want any inductance in your experiments. That is why they used copper tools to build the pyramids. If you take a granite rock and vibrate it with the "B" field it will loose some of it's structural integrity and a copper tool would be used to shape it!!..

Stay away from all iron, and any inductance!! You can use iron to make the magnets but you never want to introduce other iron or inductance to the picture it would disrupt the field you create. Know this: Our entire universe is all magnetic once you understand a little more. I believe, The eight sided pyramids of Egypt were transportation devices . Intergalactic Hologram generators that would allow for instant transportation. Once you start a magnetic field in iron it will continue indefinitely. When you lay down a bar magnet and sprinkle the iron on top of the paper .. It's the space's between the lines where all the real power is. That is also the MAIN reason AC current and radio waves traverse the distance.. We need to re-think our magnetics.. The Oscilloscope does not show the "B"/Nutron field but it is the main power that makes things travel . Anti gravity is also a big part of all this ..Just tap any plastic or glass object with the center of a magnet and watch it loose weight.. DON"T use iron or steel for this test you would disrupt "B"/Nutron field. I'm thinking systems like Stone Henge were vibrating earths energy to energize the crops in the field and many other earthly needs.
