- Every AC machine uses a rotating magnetic field, an invention that kicked off the industrial revolution. Can you guess how the RMF reached this stage! In this video, we’ll travel through the minds of the geniuses behind the development of RMF. The greatest contribution can perhaps be attributed to Nikola Tesla, considered by many as the pioneering father of modern engineering. To understand how the design theories evolved over time, our trip will take us all the way through to a glimpse of modern-day winding techniques and RMF production.

Salute to those Great Engineers ... 🙏
I'm liking industrial designers too. Everyone forgets. Remember Raymond Lowey and that other guy. I forget his name.
This is what we need to learn in this modern world instead of boring texts and pictures.
Now try to build one eletric motor with this knowledge.
Exactly
I loved it but gotta admit. To properly understand it, I'll have to rewatch it many many ntimes
Me too!
It's not complicated enough. They had to make the arrow point to the south pole of the coils instead of how a compass is arranged pointing to the north pole? Is there a plan afoot to mix us up? Come on, people. Why do that? Just another small pebble in the road.
What's with the dynamo @ 4:37 "...Galileo Ferraris used an inductor in one
of the two coils supplied by a single-phase ac dynamo later..." This video is confusing.
@dasara doodla Yeah, I know that and you know that, but that's got no business in a 101 course. This is bs.
@Caishen Salelius 6022 My physics professors did not confuse us. There's another animated video out there that should be good too but suffers from the same thing. Too many moving parts with captions and narration. And music and sound effects.
Interesting thing about knowledge and teaching. I think I'm seeing a good video or lecture when they explain things that I know already. But on further examination, I find that the explanations sometimes fail to explain clearly, things that I haven't learned.
Our judging system is skewed a bit and tells us things that may not be true.
PS. sorry this is so windy.
No words to say about how great your videos are
This was the first time I fully understood the efficiency difference between split-phase and 3-phase motors. Excellent
Tesla built the first a.c motors, but Charles Steinmetz, head of the original General Electric research laboratories, made A.C power transmission engineerable with his mathematics and theory, and therefore made the use of A.C possible. Before that Oliver Heaviside took Maxwells equations and simplified them to four short expressions; Maxwells equations as we are taught in school should really be called Heavisides equations. He also made telegraph transmission possible by describing the mutual relationship between magnetic and dielectric fields. He showed through his telegraph equation that the problem with telegraph transmission was not solvable by loading the system with more power, but was only solvable by intoducing loading coils at certain intervals along the line. Just a few names no one hears anymore.
Thank you, for the knowledge.
Great heads up.
Thanks a lot man ...can you suggest some other videos or channel where I can learn very very basics of physics we see in our day to day life or we use in our day to day life...
"The genius inventor of all time, Nikola Tesla." wow, what a title.
He was a genius inventor, yes, but of all time? Such judgments don't belong in an engineering channel.
Tesla was much more theoretitian than inventor.
@@wfemp_4730 The smooth rotating magnetic field has defined all of modern technology. We wouldn't have solid state technology if it weren't for the AC motor
@@RandyRandersonthefamous Sorry, but that's just too much of an absolute claim for my taste.
lol I caught that one too
Great work making this hard concept simple! Thank you
Very useful video. Easily understandable. Thank you so much for the lesics team.
Keep doing 💚
my head just exploded.....I always wondered if Tesla came back today and saw all the innovations of his idea and how astonished he would be...same thing with all the other early scientists.....hmmm, sounds like a good movie
Companies and overly dramatic writers would absolutely destroy it
really?, I thought he would be disappointed, because people implement his ideas in Edison ways
He was no doubt a great inventor but there’s a lot more people who developed ideas much higher in technology
Astonished? I’d say disappointed , all this 100 years ago and we did nothing new with it, we barley improved on his , And now we cheapened it all for bottom line profits making sub standard everything. in fact he had 100’s of more viable solutions for not just electric motors , but vast amounts of technology.. we are light years behind , had he lived another 100 years we’d be using more than 10% of our actual brain power , and we’d be wasting less, and needing less ...... I think he’d say , I gave you the world and you came up with wireless porn ..
@@nadronnocojr we do use more than 10% of the brain power, but whatever. Only imbeciles complain all the time, he wasn't, he would work and try to improve. He wasn't a politician, he was an engineer, and those don't start whinning when things don't go as they want
Thank you, kudos for this clear emulation video that brings understanding about RMF in AC motors. Keep creating useful, understandable videos, Lesics ! :D
You're amazing in doing the hard preparations and showing us in much simpler way......... You should become a teacher.......
Thank you for the great illustrated explanation! 👍
yay!!
this is the video i was waiting for
i love you!!!

Best video I've seen explaining this on youtube
Thank you for the great visualization!!! And the inventor or genius behind the engineering world. As always, you guys are awesome.
Very well explained. Keep it up!
Very informative video, thank you!
I fell in love with this youtube channel. Many thanks for this video.
Excellent explanation, very helpful and clear.
Amazing video , it explains it all . Keep it up
Thank for making this video 👍 👍 👍
Ultra amazing! Thank you Learn Engineering!!!!!!!
Amazing channel. The best there is imo
I like your video and also enjoy your way of teaching, am lucky to have a such kind of teacher, thnks for giving us information about our knowledge
Best channel to understand stuff.
Hey team can you give details of ISS air conditioning system.
Thank you so much Lesics.❤
Great video sir. Thank you!
Damn, this video was the best.
Can't believe Tesla didn't look at his 2 phase diagram and think hmm, something's missing here, a big gap between these 2 phases 🤔🤔
really well explained and concise video on how AC motors work!
perfect as usual ♥♥♥
Excellent explanation SIR
Thank u
Great job !
Extremely helpful
Excellent work
Outstanding! Impressive! Visuals and information excellent. Thank you very much for such a beautiful presentation. Joel
Hey,
Plzz go onn making such video's on Sir Nicola Tesla's innovation and Engineering Marvel......I am pretty sure that one day your videos will come in TH-cam's trending page.
If that's the case everyone's would be an engineer 😄
WONDERFUL!
Nicola tesla is a true genius 🤘hats off to his thinking capability 🎩
I think in that case he just improved the creation of Walter Bailey and this is a lot more easier than create something new.
And Mikhail Dobrovolsky's design was superior.
@@akilarodrigues7065 true but have a look at his other inventions those are simply awesome 😍😍
@@CorruptionManX Is it?
Super explanation🙏🏼🙌🤝👍👌
This channel is goated
in my opinion the 3 phase wiring is more of an evolution than a revolution to the design tesla created, not to say it wasn't a big deal, but they just used what tesla had already figured out and improved it to make it more efficient
Even the two phase was an evolution of Bailey’s original step change design. The fact that you could have a single vector and have that move, whether in stepwise or continuous fashion, by altering the current was his idea.
What will happen if we increase phases? Like from 3 to 4 or 5? Is it possible? If not what are the limitations?
@@starboy001 I'm pretty sure the eddy effect will increase or simply not be beneficial enough to be viable
Wdym? Tesla wasn't the only one to figure it out. Did you not watch the video. Ferraris had figured it out as well. Give credit where credit is due. Only thing that Tesla did different was patent his idea whereas Ferraris did not.
And as a matter-of-fact Ferraris and Teslas design was an evolution in RMF to Walter Bailey's original design, so...🤷♂️
Great work.
Very Nice Explaination
Awesome video 👏
beautiful
Great Sir NicolasTesla
Nikola Tesla ❤ True Genius
U R the best!
Excellent 👍
excellent
Love it...❤
Very interesting video!
That's one hell outta video
We overlook most of the scientists who realised the dream of "modern day"
So true, my friend. It makes me wonder how much we may not appreciate or understand the significance of today's people and current scientific developments - all over the world. As they say, Tomorrow's Yesterday is Today. If that makes sense :)
We cannot always think of how a transistor works every time we tap the smartphone screen.
@@godson200 atleast we should know how it works
@@godson200 xD smartass
@@Charlie-Oooooo Everyone says "Let's not get too technical" while they pray to a nonexistent god. Better they should give thanks to the boys and girls who have studied hard and brought them all the luxuries of modern tecnology. So sad.
Thanks 🙏
Make a video on winding mechanism of today's motors👍
The key to understanding this is the notion of induction. Anytime a current is passed
through a wire, a magnetic field in “induced “ in the opposite direction. Electric motors
Make use of this “induced “ field by getting it to do work. It is one of the coolest
phenomenons in nature.
When a current is passed through a wire, magnetic field is not induced in the opposite direction, it's actually induced in a circular path according to right hand rule.
Very useful animated video.
But seriously how the heck do people come up with these ideas of creating a rotating magnetic field using interwoven coils like that 🤯
It's easy. They're interested and don't watch TV. Although Leave it to Beaver is pretty good.
@@alext8828 yeah righto so you've come up with a ground breaking concept such as rotating magnetic fields seeing as it's so easy? Do you have references to your achievements?
@@Green__Man Quiet! Leave it to Beaver's on.
@@qoph1988 ok it was semi rhetorical but all you "geniuses" won't stop will you
Electricity has been studied since ancient Roman times.
May I ask what softwares did you use to make these videos? I want to make some animations in my work too, thanks~
thanks a lot
謝謝！
Sir please make a video on working of 3 phase linear induction motor for maglev vehicles
Great 👌👌😊.
Specifically to me 7:17 is 😮
Hello. Please, what software do you use to make these 3D animations of the equipment? It looks very good.
plz make a vdeo on winding design of three phase induction motor....
Good job
Bravi! 👏👏
Sir please make a video on working of multimeter and electricmeter
For the Walter Illustration
How is it the same magnitude when all 4 coils are energized
There should be 2 resultant arrows at 90 degrees to each other which will produce a resultant at 45 degrees but the magnitude will be the square root of the sum of the squares by Pythagoras
0:07 "An invention that kicked off the Industrial revolution" 😮Thomas Newcomen has entered the chat.
I did not understand therefore I Will keep watching more videos.
3:11 badass name
Plz make video on current wiring techniques.
We need better understanding about Coil winding method design & calculation. Please post a video
Thank
At 7:26, you have made distinction b/w N-S notation in case of PMs and RMF which contradicts the notation we saw with Walter bailey and also RMF notations explained at 6:16. I am confused now.
Legend sir Nikola Tesla....😎
NICE
Sir please make a video on MCB
Pls make the video for the winding design
Sir please make a video on multimeter and electricmeter
Great making animation 👌 vedio
Wow! Out of the blue babooska dubrovoski became the father of 3-phase ac motor! Did he have any patents at all?
Yup he has. This guy designed detailed 3 phase motors. Also a good amount of work in star delta connections
dear sir can you please explain the start winding of a oscillating van motor with a capacitor
good channel and video
Please make video of "How current flow in drone?"
Why does Walter Bailey did not make holes in the plate to reduce Eddy currents? Is it possible to do so? Or will create any other issues?
Please tell 🙏
Make video on modern Advanced windings ASAP
Please make a video on Cold start and Hot Start of old diesel engine.
In old cars we have to push heat button first for some time then it will start.
You still have to do that in new cars, just leave the key in the on position until the glow plug light turns off and then start as normal. This is because diesels are compression ignition engines (Rather than spark ignition like gasoline or CNG/propane/butane engines), so the heat that causes the fuel to begin ignition is created by compressing air in the piston (It gets hotter because as the piston moves up, a fixed mass of air is compressed into a smaller area, packing the energy in that air more tightly, which manifests as a higher temperature - this is one consequence of the ideal gas law PV=nRT - expanding a gas will make its temperature reduce too, which is the basis for refrigeration systems).
When it's very cold, the combination of a cold engine block and cold air being pumped through the engine mean the ignition temperature of the diesel is not reached, so when the fuel is injected it doesn't ignite. The glow plugs heat the engine block enough to allow ignition to take place. Once the engine has started it generates more than enough waste heat to warm everything up enough to keep running without further electrical heating. Cold weather also makes the engine oil thicker, so the engine is harder to turn, and reduces the battery current available to the starter, so these also contribute to cold starting issues in gas and diesel engines.
Great
Hi. Minute 6.19 North is shown where the field goes out and south where it enters. I suppose it should be reversed?
Awesome *infinity
Neat :)
🤜🏻👍🤛🏻♡♡♡
Wow.
DC motory also have a rotating magnetic field. They just need a mechanical commutator to acheve it, while ac motors need electric comutator if ran from dc source
