Understanding RMF | The driving force behind every AC machine
Вставка
- Опубліковано 9 лис 2020
- 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 was the first time I fully understood the efficiency difference between split-phase and 3-phase motors. Excellent
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 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
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...
This is such a masterpiece illustrating the concept through its historical development in such way it is easy to understand.. Thank you!
Great work making this hard concept simple! Thank you
Thank you, kudos for this clear emulation video that brings understanding about RMF in AC motors. Keep creating useful, understandable videos, Lesics ! :D
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
You're amazing in doing the hard preparations and showing us in much simpler way......... You should become a teacher.......
I fell in love with this youtube channel. Many thanks for this video.
Thank you for the great illustrated explanation! 👍
Best video I've seen explaining this on youtube
"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
Very informative video, thank you!
Excellent explanation, very helpful and clear.
Thank you for the great visualization!!! And the inventor or genius behind the engineering world. As always, you guys are awesome.
Amazing video , it explains it all . Keep it up
Very well explained. Keep it up!
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
Amazing channel. The best there is imo
yay!!

Great video sir. Thank you!
Very Nice Explaination
Thank for making this video 👍 👍 👍
Ultra amazing! Thank you Learn Engineering!!!!!!!
Excellent work
Excellent explanation SIR
Thank u
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 🤔🤔
excellent
Best channel to understand stuff.
Hey team can you give details of ISS air conditioning system.
Great job !
Extremely helpful
WONDERFUL!
Thank you so much Lesics.❤
Great Sir NicolasTesla
perfect as usual ♥♥♥

Good job
Very useful animated video.
That's one hell outta video
Great making animation 👌 vedio
Love it...❤
NICE
0:07 "An invention that kicked off the Industrial revolution" 😮Thomas Newcomen has entered the chat.
good channel and video
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 UA-cam's trending page.
If that's the case everyone's would be an engineer 😄
Thank
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?
plz make a vdeo on winding design of three phase induction motor....
Make a video on winding mechanism of today's motors👍
謝謝！
Bravi! 👏👏
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...🤷♂️
May I ask what softwares did you use to make these videos? I want to make some animations in my work too, thanks~
Great
Plz make video on current wiring techniques.
Hello. Please, what software do you use to make these 3D animations of the equipment? It looks very good.
3:11 badass name
Pls make the video for the winding design
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.
Make video on modern Advanced windings ASAP
We need better understanding about Coil winding method design & calculation. Please post a video
Awesome *infinity
I did not understand therefore I Will keep watching more videos.
Hi. Minute 6.19 North is shown where the field goes out and south where it enters. I suppose it should be reversed?
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 🙏
Legend sir Nikola Tesla....😎
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.
Sir please make a video on working of 3 phase linear induction motor for maglev vehicles
Please make video of "How current flow in drone?"
Sir please make a video on MCB
Sir please make a video on working of multimeter and electricmeter
dear sir can you please explain the start winding of a oscillating van motor with a capacitor
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.
Happy diwali sir
Neat :)
🤜🏻👍🤛🏻♡♡♡
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
Sir please make a video on multimeter and electricmeter
Wow
can you make video about working of computer
Using which software
Wow.
i was doing some experiments on induction motors and this video is gold
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.
