Electricity comes from induced EMF. Alternator i generator, please see this videos: ruclips.net/video/mq2zjmS8UMI/видео.html ruclips.net/video/HmCK2zMayoE/видео.html ruclips.net/video/_Br9FWaD45E/видео.html
so if I understand this correct it works by electrifying the copper wire (which has a winding of a certain angle because of how the sinus wave works) at first creating a magnetic field using the car battery (DC power) and when it rotates it phases the magnetic field super fast using the negative and positively charged magnets which creates more energy that it had before?. Like moving your hand back and forth in a volume of still water creating a movement of force heh.
Yes, car battery will "create" the magnetic field, but after the car has been started the alternator can create the magnetic field itself. From there the rotor rotates within the stator (set of coils that are fixed to a shell and dont rotate) and an AC current is produced. AC current will then be converted to DC current to create an output voltage to your battery. The regulator on the alternator is the component that determines how much output voltage your battery receives.
I think the pole markings should be swapped since the typical convention is that external magnetic flux lines come out of a N pole and go into a S pole. I also noticed when the 1-phase animation starts, the N and S poles in the 2D view are opposite the 3D view (so the 2D starts out correct) but things get out of synch and towards the end they match up so both are backwards. I imagine it was a challenge to synch everything up when creating this. Also, the current magnitude and direction look correct in the 1-phase 3D (good job) but it looks like it might be opposite in the 3-phase animation (both 2D and 3D). However it's kind of hard to tell with all that is going on in the 3-phase animation.
Essentially what we are all used to seeing in diagrams are 2D representation of the magnetic field. In reality magnetic field is 3D and would have a field as the video showed. But as you mentioned there are still line going from N to S as well.
Can you explain how there is emf produced at 2:33 when for some time there is no change in (BAcos)? The change only occurs when you change the poli from S to N for example and then there is 90 degree angle untill it changes again.
revolving magnetic flux now intersects the armature coils, which is fitted around the rotor. This will generate an alternating E.M.F across the winding.
Could you explain a little bit more? Because I can see by the I graph, that when magnetic field is right underneath horizonatl part of winding, there is I=0. I thought there would be max I since magnetic field is perpendicular to the velocity of wire and so sin90 would give max I?
Model in video is 4 pole rotor, 4 pole rotor has got 2 pairs of N-S pole, when the rotor turns a half revolution the induced E.M.F takes one complete cycle. So it is clear that frequency of the induced E.M.F is directly proportional to the number of poles and rotor speed. It can be easily established that frequency of induced E.M.F f(Hz), rotor speed N(rpm) and number of poles P are connected through the following relationship F=PN/120

Good explanation but the translating computer voice is distracting to much...

Good work
which software you use to create it?
I use 3D max and Adobe after effects
thanks
Perfect video. Do you know why car alternator have the rotor winding that don't produce perpendicular magnetic field through stator windings?
Excellent video! I appreciate the time and effort it took to produce it! It really helped me to understand the workings of an alternator.
No problem
Is there current is made from delta connection?
@ 1:10 How does Rotor produce magnetic field. Is there any other power supply given to rotor? @ 1:48 where does this electricity come from?

I think that i made correct explanation, but i will watch again from the begining to see, maybe there is something error
Very Good explanation..
😊
Please give armature winding class
Thanks, good one from you
Thank you for explanation, it does help me understand more about the Alternator.
Thanks
This is very well understood... but I again want an explanation on how does it kick start the flywheel of a car
Martin H Joseph this is an alternator.. What you need to search is a starter motor.
Thanks I got it right arleady... thanks again for your video production guys we are learning alot from them
Nice animation
Thanks,
good explanation thank you sir
Whats does enf mean?
nice and clean explanation
very good animation. I waiting for your more video.congratulations,
Excellent,I like it
Very very easy explain sir ,awsome
Good
You do realize that at 2:35 you are showing a cosine wave and not a sine wave, right?
Well, I thnik that you are right
Type 2 is dc or ac generator
1:48 - shouldn't lines go from N to S ?

What do you mean by (BAcos)?

@ 1:44 In these coils where is power coming from????
From. A DC supply

Thx
No problem

Why use d.c generator in here shaft ?
Very nice vedio sir
nice vedeos
Why it sound like tamil
Im gonna make my own tesla 100 add 4 alternators to each wheel and safe even more electric to recharge the batrrey to get more miles 😂
I don't understand
Tharun gajavelli I will explain to you how it works
😊👍👍👍
We can not understand so easy language

Yesterday my alternator seemed like it was here to stay. Now it seems as though it won't charge my battery. Oh I believe in yesterday.

Can anyone try this out and give feedback? scout androidcircuitsolver on google
Too hard to use your own voice?
Robot voice... I'm out
As I wrote i dont have good english so maybe better is robotic voice then my mix english (Balkan with Russian akcent)
@@chrvoje_engineering ahhh Im sorry man your right I should of read the description first
no problem friend do you have good idea for some videos?
@@chrvoje_engineering I'd like to see a video on how limited slip differential work vs opened differntial and maybe lockers in there
