spectacular quality for youtube
Man you can't get these feels while reading the books and it's pretty hard to imagine thanks for animation now it is easy to imagine.
esiste una ditta che lo produce da poterlo comperare? grazie
@@giorgiobeltrami7333 I don't know about that but I can recommend you some books if you want to know more about it.
🌹💯😘
@@aram8832 can you please reccomend those books
Ya you’re lucky man
Dear god, you guys are like saints. I understood Alternator better from this one video than my professors 100 minute lectures. My basic understandings became very clear and I did the maths from my text book. I got an exam on this tomorrow and hopefully I will ace it. :)
In what profession are u now?
Be a Muslim..coz Islam is the only religion based on real proofs...and if u look it up sincerely , you will find it much more clearer than this video u admired
@@منوبيالفلسطي Alternator was invented by christians
Did you ace it??
I wish youtube was there during my days at school.
You mean. I wish youtube was here in my days of high school
You mean i wish theres a thing called youtube in my schools day?
youtube is a threat to school but as youtube is controlled by the banks its censures a lot of information to

@@Earzone63 deleted it for you Mr Nice Guy
You have explained physically and practically showing all aspects. This is very help to realize the students how Generator works. This is real education.
The best video of generator illustration I ever seen, this video really helps a lot for me to understand how a 3-phase generator works. Thanks!!!
this 5 minute video explain shit better that my professor with his 50 minutes of head torment
exactly
lmao
Rifat Urmil it happened with me also. The professors seems don't want which the class is knowing about it. They lefts majority class in unknowing. Until nowadays I wonder if it is displeasure to explain or didactics missings.
what was your major?
Cannot agree more :D
This channel is the most helpful I've ever studied with !!
Very good explanation on the principles of an alternator, thank you.
This is literally the best video available to understand working of alternators
you have saved my grades for the first year of uni! These videos are absolutely fantastic and so clear and easy to understand! thank you sir so so so very much
What you work in now ?
I've learned more in this 5 minute video than I have after hours of reading my textbook. THANK YOU
me too
I think the poles are labeled incorrectly, as typically a N pole should have magnetic flux lines going outward and inward for the S pole (the flux line arrows appear correct based upon the DC flow through the rotor coils). And the current should be maximum when a rotor pole is directly across from a stator winding, not when the winding is in between the poles. Then use "Flemings right-hand rule for generators" to get the direction of the current. As best I can tell the current directional arrows might also be backwards, but it's hard to tell with the current shown as zero at the incorrect time. Otherwise it's a pretty nice animation.
I think you are right but how cant it be that nobody say anything about that? How can it be that an expert with millions of subscribers says something so wrong? Faraday Newman law is the base for this kind of things....So are we really right?
@@marvnet8898 Not a big thing that a million subscriber can say something wrong, all over they are also humans.
You are a legend,
Many times I read but can't understand if understand something will forgot in two days, you are made me understand in easy way. Thank god(lesics)
phenominally detailed video. Absolutely loved it! Thank you guys SO MUCH
One of the best video to understand the alternator working..Thank you.
You are Doing Great Work Sir . Thankyou So Much. Very Helpful Videos. With the help of these videos, anyone can easily understand the principle and working of important Electrical Engineering topics. May God Bless You.
Please keep on uploading this informative content
I am an engineer of electronics. Spontaneously it came into my mind and heart that it's my duty to like and appreciate your fabulous work( i am little busy and lazy too ). truly you made a fine video.
Thank you. Vou dos a Nice job.
You dia a Nice job.
Excellent graphics and explanation - thank you
2:17
narrator: it is clear...
someone: chip
narrator: ... that ... frequency
at 4:34 also
I was reading this comment at that exact time 🤣👌
I love your teaching patterns
Nice video. I believe that, if you view 01:28 of the video, the rotating field has poles at 9 o'clock labelled as "NORTH" and 12 o'clock labelled "SOUTH", but the winding direction is the same viewing the pole face: this seems to be a contradiction of the right-hand-rule; the winding directions should be opposite on the adjacent poles.
Yes jerome whelan, the direction of currents there should be in reverse direction
jerome whelan hi
I was going to comment the same thing. However I am not sure whether the currents should have inverted directions or just the labels N and S should be inverted.
Thank you for producing this very helpful guide to the inner workings of alternators.
Thx alot man
You saved me for my tomorrow's exam.. Now i understood what exactly is an alternator
Are you still saved
CHANAKYA SINHA lol
Nope, After 5 Years, i'm Quarantined ...
@@sandeepa2732 HAHAAA we all with you
Thanks very much for this helpful and inspiring video.
Excellent animation!!
Thank you, Sir!!
This is possible or not? In generator stator side we give AC input so as time varying magentic field is vary and so chainging magnetic flux is Link with armature and emf is produced So here there is no need to rotate the rotaer to turbine?
Such a beautiful explanation as compared to others till now I have seen .Thank U for teaching so transparently.
Excellent video. Before watching this video I didn't understand how the windings were physically laid out in the stator and rotor, but now it is very clear. Great job!
Thank you，so easy to know the theory about the generator through this video!
i can not thank you enough....i just love you now....can you do something on dc generator and and dc motor too...
god bless u..
Yes they are in pipe line. You will see them in 2-3 months. Thank you :)
Moshiour Rahman VG vvv
Finally understand the exciter purpose in this video. TY
Your magnetic flux lines in the rotor are shown going from the south pole to the north pole, but I believe they should be going from the north pole to the south pole. Aside from that, great video!
What a great video with perfect illustration! Thank you a lot!!
all this information goes through one ear and out the other

very clear and concise explanation within 5 minutes.
if the armature coil was fixed to a second rotating axle, you could create an electric clutch by adjusting the voltage on the rotor and armature coils.

How I love Lesics just for the mere fact that they always boost my love for engineering every time I watch their content.
Awesome. Excelent tutorial! Congratulations.
Splendid video, very clear.
Super visual explanation
Thanks for this video, I find the explanation is very clear.
that was outstanding .can you post one on how to calculate the size and number of turns of each coil?
looks like LE is saving it self with these 1.76 million views.
Nice Tutorial !
Greetings from Islamic Republic of Pakistan.
Please keep making these Interesting Educative tutorials ;)
hi
When did Pakistan become Islamic republic of pak?
Very instructive video. Thanks for posting.
Great video. Greater detail then all the others. Had one question.
Are the magnetic lines of flux "flowing" in the correct direction on the rotor windings?
They appear to be south to north instead of north to south.
The lines are not pointing correctly. N pole should be pointing outwards.
Such a great video, to understand about the Alternator. This is real Engineering education. Keep doing good things.
Great vedio and precisely explained , u r doing a good job
If permanent magnets used for 3phase generator like this shown the voltage in the rotor field is then non adjustable ...so voltage regulator job lot harder and additionally this generators are gigantic would require very big permanent magnets .Permanent magnets have constant field production this would be very difficult to handle as well expensive.
I think he said PM when talking DC motors which would be correct. As these are single phase motors!
Yup, PM generators are more usefull for things like small wind turbines etc where an inverter is connected to the DC supply of the alternator.
Just a 16 year old reading these comments and doing his project. Also i have never seen an alternator in my life but thanks for the basic understanding
Sorry for the question, but since the rotor coils are excited by DC current, we would be using electricity to make electricity?
It's good to generate 1500 MW by using 250v as starter. Isn't it bad ?
The DC generator supplied the DC current that is converted to AC. The motive force for the system is provided by an outside source. The alternator in your car, for example, gets its motive force from the alternator belt attached to the drive shaft of the car's engine. It's not clearly explained in this video.
Something like that, anyway you need an external mechanic work to really generate electricity. You can also see this kind of electric machines with permanent magnets such as the brushless motors, instead of the rotating coils. These machines are also used as constant RPM motors, when you have variating loads Ex. an elevator. Also in the past they used this machine as a cos fi corrector due to it can act as an inductive load, as any other motor, or a capacitive load. Instead of using banks of capacitors. Anyway the rotor coils use like a 1% of the electricity that consumes or generates the machine. These datasheets are studied in every single motor and there exists a lot of maths to determine the parameters.
Very true.But a small amount of DC source i.e. Dc input is required.Afterall the output we obtain is a 3phase AC voltage.😁😁
I was asking the same question good thing I found yours..lol so what would be the difference to this kind of of generator to a generator with permanent magnets? jsut correct me if my statement is wrong :3
It didn't take long for me to get lost ! However, this is a great educational video thank you. I will continue to try to work it out !
What a great video. Had no idea how alternator made/works. So what happens/causes my car's alt to not work anymore? What is the usual part that breaks? Is it not spinning & all the internals are still good or vice versa.
symptom for alternator failure battery charge gets down probably firstly a service or battery signal arrives in the dashboard cluster finally cars get off if it is an electronic injection. check out if abnormal sound coming, if bearing, if not check the mounting and belt tension and then finally check the terminal connections after inspecting the above you please start your car and check the voltage with the multi meter if the voltage is in the range of 11 to 12v for five minute interval, then your alternator is working other wise please visit the nearest dealer.
in most cases the brushes get worn down and stop giving the needed voltage to excite the field. Nowadays folks tend to just replace the alternator thinking if the brushes are worn the bearings are probably next. Soooo, the market has favored that and alternator brushes are not available for every version in the field. I tend to disagree. If you can find brushes for your alternator then inspect yours. If the brushes look un-even, or are pitted, and look like they have been burnt replace them. Its a pretty simple process on most vehicles. Take the opportunity to clean the slip rings with a commutator stone too... It will most likely get you charging again!
great explanation with great animation.. 100/100
YES..GREAT VID GUYS!!
Excellent explanation .Very much useful.
Engine peak rpm is around 8000 and with the pulley ratio of 3:1 the rpm at the alternator becomes about 24000. So if I am not wrong such low rpm range ac generators are not used in an automotive industry. What kind of an alternator have you considered in the video? and where are they used?
hydroelectric power generators maybe running on low rpm...wind power also low rpm...better to be low rpm, because less wear and tear to the parts
most manufacturers don't use the slip rings any more to reduce maintenance time/cost, but a cracking video nether the less!
Minute 1:29 I think there's a mistake in the sense of the currents (just 2 of the coils), because it doesn't correspond with the magnetic field shown. Can someone check it? Thanks!
You are correct. The top and bottom coils have currents going in the wrong direction. The direction shown should produce North poles not south based on the right hand rule of magnetic fields induced by looped currents (up for CCW and down for CW).
I noticed it too, they placed there N and S at the wrong places
Excellent animation pure explanation 👏
thanks for the awesome explanation! what's the amazing software used to show the alternator's functioning?
Learn Engineering....Great video with great animation. It is better if you can develop this video to show brushless alternator funtion as well. Those are the most common now a days.
why doesn't the rotor use permanent magnets instead of DC electromagnets?
It is well possible to use permanent magnets. Small alternators usually run with it.
one of the disadvantages of using permanent magnet is the magnetic field relatively constant, isn't it?
Linda Kurniawati yes but that doesn't matter because the amount of drag on the rotor will always commensurate with the load (electrical resistance) on the coils so the more current you drain the higher the drag and vice versa.
because then it would be a dynamo XD
TheSoxmania nope because you will still have magnets swiping across the 3 pick up coils. As a magnet nears a coil it produces electricity in one polarity and does the same and it moves away. A dynamo is made by rotating the coils within a permanent magnet field, the rotor's interface will be brushes instead of slip rings.
Excellent video, short, precise ..........amazing explanation Thumbs up :)

@@gnagimovbro learned math from the back of a milk carton
Really liked it excellent. But Can you please give this kind of video for armature reaction of this.?
I wich I had a Professor like you teaching me the subject
Me too
This video is very useful. It's gives a complete overview of the concept. Thanks you for uploading it!
Is there an Alternator that uses magnet to generate magnetic field or all of them only uses electricity to create the magnet field?
It does exists its called fixed magnet alternator.
I had a magneto on my bicycle.
Another excellent video but I have just one comment to make. You refer to the fixed coils in the casing as armature most of the time but as stator occasionally. Strictly speaking the armature is the rotating core with coils, slip rings and iron pole pieces. The outer series of coils are the stator. By using the term armature for the stator there is a risk of confusing students. I know because I teach automotive engineering and my young students can get easily confused. However, a really good teaching aid and I will be using it, along with a few explanations of terms, in my classes. Many thanks for making and posting this.
1:55 isn't magnetic field comes from north pole to south🤔
Amazing animation.Thank you.
nice information
I could listen to him all day !
1:28 wrong diagram representation. Working on without magnet projects vlog. You can watch it not a promotion
Thank you. I was very confused. Nearly thought that something is going wrong with me .
What's wrong, the polarity?
@@CombraStudios the direction of field lines is wrong. Use right hand rule you will get that he has drawn the feild lines in the opposite direction.
@@Dhanush-zj7mf Hello, I just used the right hand rule for the 1:27 pic. It shows the N coils are correct and the S coils show cyan arrows in wrong direction
@@CombraStudios yeah. I am said the same
Best animation so far
someone can tell me why magnetic field comes out from south pole and comes in to north pole? Isn't it on the contrary?
its just that the notation, no problem...
Never seen such wonderful explanation. Thanks @learn Engineering

Okay, good, Ian Knau. Thanks for finishing your thought this time.
Uh, nope, Ian Knau! But I can see that *you* are, since it looks like you got all butt-hurt and took offense to something where none was given. What's your big beef with someone who sincerely *thanked* you for making yourself clear after you hadn't been before, so much that you figure you should be a big *dick* in exchange for their gratitude?

OMG, it's explain 99% of my doubts! Thank you
Not to look a gift horse in the mouth, but me thinks English is not the writer's first language. I think the narration is done by a bot.
Yah, I am from India. English is not my first language.
your accent is pretty good. sounds like you just did some post editing :) well done video.
Learn Engineering Hey man love your videos! If you ever need a narrator or lessons in British English pronunciation I would be happy to help!
one of the best sounding bots i'm sure its feels ok to listen to it :)
I'm from London and CGI animation is not my first language, I wish I could do it as well as you have here
Very comprehensive explanation and good animations as well
Alternator is a misnomer, it is an electrical generator. End of story.
alternator happens to be a part of the generator genius
I don't think so. As the produced emf by AC generator is of alternative nature (i.e, the curve of produced emf alternates in a certain period of time), it is called as Alternator. So, it's not a misnomer.
Your video gives very good explanation about alternator
Watts this about...ohhh... this hertz me as it applies to my current situation... i know...you blew a fuse... not funny... im shocked... i will go ohm now and watch the electric circus
hahah good one!

Bruh what
Fantastic : clear. Now I can understand how an alternator works !...
in the base,rotor cuts electromagnetic field between rotor and stator coils,in that situation electric charge began to produce ac electricity.Stator coils are connected to the diode unit,and they convert ac power to the dc power.Regulator is connected directly with a rotor colector and diode unit ,and by that he regulates dc electric charge between 13.5v -14.5v. to the battery.
Absolutely awesome every concept is made to understand in crystal clear format . Good for beigners , it could also be used for concept revision purpose a day before exam
Thanks for useful information.. plz also give video about connection of rotar coil and starter coil .
Thanks bro.. your explanation is outstanding thanks once again🙄🙄🙄🙄🙄
