The invention of induction motors permanently altered the course of human civilization. This hundred-year-old motor-invented by the great scientist Nikola Tesla-is the most common motor type, even today. In fact, about 50 percent of global electric power consumption is due to induction motors. Let’s get into the workings of induction motors, or more specifically, into Nikola Tesla’s genius thinking.

This one 6min video = one week of university lecture
well done!!!!
pretty accurate :)
We learned this in highschool
can't agree more
@@smrtfasizmu6161 you mean you were exposed to some watered down explanation. This video is pretty watered down itself. Electromagnetism is one of the hardest physics topic you'll learn in college.
@@smrtfasizmu6161 We would have learned it in high school too if you Russians hadn't taught us to argue about chopping off dicks all day long in Commie-school. We need to get back to proper education, not foreign language and foreign sex classes.
I can't even begin to understand how Tesla managed to visualize this thing in his brain
Very simple: by copying the patent drawings of the first dynamo, invented by the italian Antonio Pacinotti in 1860 and marketed by the french Gramme in 1869; then copying the patent and the drawings of the first induction motor (two-phase), invented by the italian Galileo Ferraris in 1883, three years before Tesla's patent. Not everything that is electric was invented by Tesla 😉
@@andreacosta74 yeah yeah yeah save all that bullshit tesla invented it
The easiest way to imagine it, is to imagine 2 magnets. Because that's all electricity is. The N and S ends attract.. and The N and N ends repel each other. So while one winding is attracting(pulling) one of the armature poles, the one previous winding is repelling(pushing) it. Helping it rotate. Since it's AC, the one that was attracting, is now going to repel it with it then completing the cycle(1 hertz).
One knows the basic effect of fields, the rest is a series of logical steps.
No.Tesla was the smartest person to ever live. He was hit by lightning some day near a river and that hit connected a oart of his brain that made him a genius. He could read once a book and remember all.He didnt copy anyone , the others copied him. There are so many other inventions of him that in mear future we will use them such as wireless electricity.Also tesla wasnt serbian but jis parents were originated from north albania
Man this is insane! You will make guys clear engineering courses in months like such tutorials! Awesome video! Keep it up!
I just had a chapter on induction motors for my HVAC class. This helped me cement my understanding of an induction motor. Thanks for the video!
I much prefer this narrator, sounds much more genuine. Huge improvement.
The recent poll I conducted on my Patreon page gave the opposite result. I am confused now :(
A very popular CZcamsr making a comment on a video 3 years ago, and getting no replies except the video creator? I've just found a unicorn!
@@specialopsdave You deserve a like
*question* which software you use to make these videos
@@Lesics Simple explanation - the majority of the survey answers are wrong :/ This narration is excellent.

A superb explanation with excellent graphics. You really cracked it here! I've worked with these machines for 20 years and always struggled to explain them to trainees. Thank you.
Great work distilling the concepts involved in such a visually-appealing and intuitive way!
Dear friends, Should I delete the old Induction motor video? This video is an improved version of our old Induction motor video.
czcams.com/video/LtJoJBUSe28/video.html
The new video has more information and better graphics.
Learn Engineering sure why not. There is no point in having two similar videos. Great video btw 😎🙏
Learn Engineering yes delete the old version video and post the latest one for the info and knowledge for all of us, as subscribers and followers.thank you
Learn Engineering i watched both the videos back to back ....
I think this new video covers everything from previous video and extra ....
So no harm in deleting the 0ld one ....Best wishes :)
Learn Engineering No, don't delete the old video. Just change the title and put the link to this video in the description
Nax FM due to your hardwork
Wow... The way you connected theory part with the practical part keeping it as simple as possible with a neat explanation is very good.
22 years since i started as an apprentice winder and induction motor mechanic, this was nice to see, good job and very well explained. 👌
I want learn more abt Induction motor s
@@venushinde17 no
Hi sir,
One doubt
The induction motor rotor core doesn't have any electricity in it.
But how it is running
Then why it is angled
@@karthikeyanthecenterofattr2718 I have an old one in which that isn't angled. So that's not necessary apparently
@@ratubgn1237 abe chal phit tera chacha bhi ake sikhayega. 😡😡
I can't believe how easy it is to understand induction motor and the speed controller. Thank you for a Great lesson.
Yeah!!!
Exactly
Nobody has any concept of what a "squirrel cage" looks like. I use the term to my students but then tell them "hamster wheel". Everyone always goes, "Aaah!"
Great job ! Thank you !
I repaired my washing mashine lastly and I didn't know how it really worked, I only saw DC motors. This gave me the response.
This was an extremely well done video, thanks for the final's week assist :)
the visualization made it so easy to understand.
You don't know how long I've been looking for this very valuable data. Thank you so much !!!
Really this is a very nice video.
One of the best explanations for induction motors / Brammer. Thank you
wow! beautifully illustrated and explained! loved every bit! It felt like a chore to learn all this but you made it so interesting, thank you LESICS!!
Thanks a lot Learning engineering team. your all videos helping me a lot to have strong concept about electrical engineering. Also thank you for a very nice 3d presentation. You guys deserves respect. Good luck
No words to the video. It has cleared my many concepts related to induction motor. So perfect video. Thank you sir for your efforts. Please even make videos on other core electrical concepts...
The animations are vivid and beautifully edited together with the narration. It brought together a whole morning of textbook reading.
i was trying for 40 mins to understand it using the teacher's lecture. You made that possible in 6! Thank you
this video is so damn amazing, its been a week i was trying to study concepts of induction motor and this video all of them clear
Damn i wish you tube was around when i went to high school...
This is the most wonderful explanation I have found for induction motor. Without this i know nothing about the working. Thank you very much 🙏
Waw! such a great explanation with visuals.Thank you so much!!!
This is one of the best lectures with the best breakdown ever......please keep it up
Everytime I see this, I understand the concept better than the previous🤗🤗🤗
i have suffered from this topic for a week, then 6 minutes video heals me.
Just amazing..explained the whole concept within 6 mins very well..thanks
what a video . excellent graphics !. I wish we were taught like this back then. I hope the new generation makes full use of this.
What an amazing video and explanation!
This is an awesome illustration. Thank you.
This is the best video to understand the basic of induction motor. Thanks a ton!
Amazing! It would be really great to see an animation explaining the operation of an Induction Generator.
Brooooom brooooom brooooooom 😂😂😂😂😂😂
😢
That's the explanation I needed. Great video!
A lot of work went into producing this video. Very impressive.
This takes me back to my early Electrical Engineering classes in high school. Would be great if you touched on the wound rotor induction motor. Thanks for the refresher!

Thank you very much, you summarized a 1-hour lecture in 6 min!
Wow. Simply well put, I understand the basic concepts of it. Thank You!
Thank you so much for this! Could you please do a video on the electromechanical induction meter and its working principles? I would appreciate it a lot.
Best video on induction machines by far. Could have been better if the equivalent circuits are explained too!=)
Good primer and review. You cover the basics very well.
From there, someone can learn more about the particulars that go into production design of top of the line production electric vehicle motors, but at least they would have a solid foundation of understanding from this vid.
This is so BRILLIANT!! i wish it was longer
This is pure genius in my believe. I mean, the slickness of the design and the creativity that must have gone into idealizing and crafting a motor that functions in this way is simply outstanding. Tesla was truely amazing
Once every few hundred years, a person exhibits a level of scientific or technological acumen high enough and powerful enough to qualify them as beyond genius: DaVinci, Tesla...these two were quantifiably 300-500 years ahead of their time.
@@davidsirmons I would say tesla was 100-200 years ahead, but he was a genius nonetheless.
Superb animation. I don’t know if we can credit everything to Nikola Tesla but I am beginning to understand induction motors more. Thank you 🙂
Wish I had found this channel early. This is so good explanation.
Exceotional explenation. Very simple, yet detailed enough. Thx!
Hats off to the video! And to Tesla, of course!
Cara!!!
Esses vídeos são sensacionais, imperdiveis.
Congratulations.
Wow what an informative video. Within 6 mins, I finally understand the induction motor rather than in universities.
Very well done and a great narrator. Thanks.
When I become rich business man I will spend some money for your channel.very informative video .
Mr. Raju Rastogi can you explain how induction motor starts?
Raju : brrrrrm brrrrrrrm brrrrrrrrrrrrrrrrrrrrrrr brrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrmmmmm 😂😂😂😂😂
hahahahahhaha
Im working on a direct current motor that goes Whirrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
Nice starting dude
It has a moment of force, greater when speed is less, due to a rotational field, provided by inductor. At the
time this field has a reaction with the rotor, where a current was induced. This rotor is at shorcircuit.That provides this moment. Current consumption at this time is high
I am searching for this comment
Wow, awesome. I think every college should teach engineering concepts with this type of animation. Its sooo... Easy to understand.
This tutorial caught my interest cause the narrator really explained it all well and I've learned a lot from this video.
In just 6 minutes length of video
It feels like the narrator explain the whole quarter lesson
D/C used to rule the elevator world. As a mechanic, I have changed a few MG sets, that is motor/generator. A/C motor running a D/C generator. Back in the day, D/C motors were easier to control rotating speed, allowing a smoother elevator ride. Then, they developed variable frequency, and A/C motors were back in business!
My teacher should've shown this video in our class instead of explaining it in their way
Really amazing!! I can understand the whole fact clearly. In this online education system these videos are really very helpful. Thanks a lot❤❤❤
Thank you for your simplification
College: teachs me this over the course of a few hours, days even
Video:teachs me in under 7 minutes
Thank you for your knowledge, greetings from Indonesia
Caught me from failing electric machine course thanks man for simplification ❤️

Thanks for this video. Also thanks to Sir! Nikola Tesla.
Very nicely explained, well done.
Finally now Raju will know how induction motor works

Genius 👍
Very clear explanation, thank you so much...
Excelente, muy buen video. Esta era la explicacion que estaba buscando. Mis respetos.
This is so genius that I can't even come to comprehend
Completed engineering without knowing that..now understood.
Thanks
understanding this is very hard even with clear explanations and Tesla’s thought about those things are shocking me he was such a genius
Its a very helpfull video as well as very much technical content on it.
Thank you sir for such kind of representation.
Thanks to the most genius inventor in known human history. Appreciate it Tesla
I am a huge Tesla fan the man and inventor but while we pay respect to Tesla maybe we should also pay respect to Leonardo Da Vinci. Da Vinci made robots from wood, invented the helicopter, the glider, the submarine, the first diving suit, the parachute and many other things still in use today - like Tesla - he was man ahead of his time.
Amazing introductory videos with great visuals! You should keep it up!
BTW, can someone explain me what does he say after 3:45 ? "...the magnetic field will never cut the loop.." I didn't understand that part :( What loop is that?
The loop he is referring to is the rotor bars, which you can compare to a (thick) loop of wire. At synchronous speed, the magnetic fields generated by the stator and rotor are rotating at the same speed, and thus there is no relative movement between the magnetic field and the rotor bars. Faraday's Law tells us that an Electromotive Force (EMF) will be induced proportional to the rate of change of magnetic flux through a closed loop, and as there is no (relative) movement under these conditions there will be no induced EMF (and no torque).
Abdullah yuksel......Hey suppose
RMF is a thief &
Rotor is a policeman
Now you know
If policeman(rotor) is trying to catch the thief(RMF) with same speed he is never going to catch him up.
Later he is saying only when thief(RMF) will slow down , policeman(Rotor) can catch him
Thank you very much sir.... For the detailed explanation..
This vedio was really helpful.....my professor's 1 week lecture in 6 mins ....awsome
Nice
Actually electric cars use permanent magnet rotor syncronous motors because they are even more efficient due to the fact that there are no losses in any rotor windings. Also DC motors are both easier and cheaper to speed control wich is why induction motors are mostly used in constant speed applications, only recently have the price on VFDs and high powered brushless DC motors dropped so much they can be concidered affordable for general applications wich is a bit of a shame because since both BLDC and induction motors have no brushes they are whisper quiet and last forever compared to for example universal motors where the brushes both wear out and make the motor loud as a jetplane (this is why hand held power tools, vacuum cleaners and kitchen mixers are so insanley loud compared to for example a stationary drill press and a refrigerator)
John Pekkala
Not quite. Even though some eletric car companies use permanent magnets, The are some that use induction motors. One of them is called Tesla, which is, by a big margin, the biggest eletric car producer. It's allegedly a move to reduce costs, since rare Earth magnets suffered a reasonable boom in price in about 2011, jumping to a ridiculous ~1000% increase (if i recall correctly). That's mainly due to the increase in demand and limited supply.
Don't get me wrong, Dc brushless motors are currently the most advanced motors. Their permanent magnets however make them a blind shot for high volume, such as eletric cars.
Now, the reason most applications of induction motors are for constant speed has not much to do with the difficulty to control it ( considering nowadays powerful microcontrollers, and developed power electronics ) which nowadays is basically non-existant.
The real reason is that induction motors have a small torque at low
Rpm. Which forces some applications, to make it work at synchronous speed.
Tesla seems to have found a way to circumvent this disadvantage of induction motors. I'm not really gonna discuss this here.
It's true dc motors dropped in price . At least the small ones.
The problem are the magnets.
BLDC ?
As mentioned in the video, induction motors are used in electrical vehicles, which is far from a constant speed application. The new Tesla Roadster 2020 uses a 3 phase 4-pole induction motor.
bldc = brushless dc motors
John Pekkala sir in India the 3 three phase induction motor is fitted in loco motive to get high speed in Lower rpm three phase motors are so efficient and cheaper than any other
Really great explanation... everyone can easily understand the concept by watching this video...tq soo much for making such videos 🙏🙏
A picture is worth a thousand words. Well done.
Which software are used to make this video.?
Blender, www.blender.org
I too wan't to know
Was used
@@satisheswar5872 also, or I want to know, too
Do pumps used for pipes work with the same principle ?
Yes, pumps use an electric motor to drive an impeller
Beautifully explained sir, thanks a lot
what a clear visualization.................thanks a lot for this
Make more such electrical engineering videos so that we don't waste our precious time to go to the college ....
Thomas Edson my ass! The real genius was Tesla!
Nikola tesla my ass! The real genius was Pacinotti
@@silviamontagna7443 no nikola or pacinoti only pubg
@@silviamontagna7443 without Pacinotti there wouldn¿t be a Nikola Tesla?
Even though Tesla seriously worked on induction machines the credit for the basic invention goes to Ferraris. Tesla used rotating magnetic fields (RMF) created from a two phase system. A two phase system (as well as a three phase system) solves the main problem of a single phase feed which represents itself as strong power pulsation between zero and a max value over time. Two phase and three phase systems are both able to provide a totally smooth power flow from the grid. With that prerequisite, a constant torque over rotation angle becomes possible.
Tesla seemed to have been stuck(?) to the idea that the rotor must be "connected" with the feed (two phases). His double loop rotor was the reason for a still considerable pulsation of motor torque, see video "Asynchronmaschine nach Tesla" (in German, there are also references linked). It must be mentioned a two phase system could have solved the pulsating torque issue, which was caused by the (double loop) rotor.
While Ferraris did not have the pulsating rotor torque problem with his massive copper rotor the final solution came from Dolivo-Dobrovolski's invention of the squirrel cage rotor (which fixed Ferraris's drawback of huge magnetizing and eddy currents). At the same time it became clear that the creation of an RMF is better done with three phases (with regard to load on every used wire over transmitted power).
It is sad to conclude but our nowaday's induction machines do not use invention's from Tesla.
@@quellstrom
Yes and pigs can fly like another great (rofl) italian inventor Marconi who invented radio?
Tesla spoke about AC current and 2/3 phase system in his first year of college (1875) in Graz but professors laugh on him because by them it was impossible and yes it was until 15 years later Tesla come to the US and proof them.
The animation and the explanation was top notch. Thank you!
With such great Clarity, u explained..😍😊 Thank u
