Understanding electric motor Windings! 

I'm a Physics and Engineering major and still struggled to follow this. The brilliance of Tesla to have visualized this without the aid of simulation software is astounding.

I am truly impressed. Whomever is behind this video has both the most clear understanding I have seen of motor windings and the mastery to animate his knowledge which makes it even more impressive.

Great job. I majored in electrical engineering and then a master's degree in power electronics and now a motor control engineer for e-drivetrain. I have never seen such a clear and vivid demonstration of AC machine windings! Thank you very much

First time I see someone animated an entire motor coil winding! You sicken' me. I should share this to my friends.

Outstanding video! I’m an electrical instructor on a limited budget, and these kind of videos are worth their weight in gold. Someone with deep pockets needs to sponsor more in depth training videos like this. Electricity can be taught much more thoroughly and efficiently with these animations.

You are the rarest youtuber whose tremendous hard work & dedication is hidden behind each beautiful video content 🙏

This is absolutely beautiful and majestic to behold. Definitely years and perhaps even centuries to get to this knowledge level. Fantastic animation and explanation.

Great explanation and animation - imagine how Tesla was able to envision all of those figures on his own by using his imagination and while walking along the park. Such a great imagination and brilliancy.

Every time lesics tackles motor windings they add beautiful knowledge into the world.

I’m so glad people are smarter than me who can design and develop things like this. If it was up to me, we’d all be living in caves still and whacking each other over the head with rocks

We used to spend many hours trying to analyze and visualize the rotating fields from text book in the old days. Few can imagine it. Students nowadays are lucky to have animation.

I didn't understand one second of this video, and i really really tried!!!

If everybody had the privilege to acces interesting knowledge like this, we would have much more engineers. Amazing content and with those concepts in motion, everything seems so much clear. i really appreciate every video i watch here. Thank you so much, great work.

I am currently working in a motor repairing shop and this video has been useful for me to understand winding concepts

You can also note that these motors are often characterized by ERPM which is how many times the any point on the “stator” passes through a north-south pair of magnets. Divide the number of ERPM by the number of permanent magnet pole pairs to get RPM of the motor. ERPM is typically the limiting factor of these motors (due to switching speed limitations) so the less pole pairs you have the faster you can go. It’s a speed/torque trade-off.

It’s over my head, I wonder how many times I would have to watch this in order to understand it. Many many. And many more. Nice animation.

The best video to show rmf with clear cut explanation. Every EE student should learn from this.

Increased my understanding 10-fold. Thanks

Tesla was one of about eight different people focused on maximizing rotational power using coil windings at the time. Every one of them came up with innovative solutions (generators, motors, transformers, squirrel cage/slip ring rotors) that were patented, published and put into production. Ferraris (motor), Wenstrom (generator), Haselwander (generator), Dolivo-Dobrovolsky (slip ring/asynchronous motor, delta-wye transformer) and others, each made major contributions to three-phase AC. And all of them were just pushing the envelope forward from the major innovations made at Ganz Works in the preceding decades.

This is the most beautiful video explaining the winding, thank you so much for it ...

Lesic is a guru in this field. Excellent!❤❤❤ I have a B.S. degree in Electrical Engineering, and after watching this video, it enlightens more my understanding of induction motor. Wow!

Something I have always been curious about, and after seeing this simple animation....I realize just how little I know.

Huh, always thought the wires in the winding were isolated from one another. The more you know. Thank you for all the educational videos you make

Tesla has found 2 phase RMF. Dobrovolsky has found 3 phase RMF.

I'm stoned, eating tacos, and learning about RMF and stator windings. How's your Friday night going?

This channel is just Marvelous, I really want to say Thank you to those who create this content, teaching very interesting topics. Once again, Thank you very much it is a Magnificent Knowledge you share with us.

This video was brilliant! I actually learned and understood this concept. This is what i've been telling to everybody - using visual language similar to this video would make children learn faster, even those who has dyslexia.

I was once a motor rewinder with out a machine,used my bare hand to make a coil,I'm happy now there is already a coil winder machine,easy job for a rewinder.

Thank you very much. I've always wondered FOR YEARS what prevented the current from seeking the shortest path. It was the varnish.

This is a very difficult abstraction for me and your illustration helped ALOT thankyou. Someone who can visualize this intuitively are going to create some very cool things :)

Simplifying the Complex. Great Work Team LESICS !!!

Extremely well produced video. Makes things so clear and logical. But at the start, there is the elegance of Tesla's thinking...despite the fact that he didnt really knew or understood how electromagnetic fields really worked, like many engineers and even scientists at the time! They were the pioneers... And now, one century later, we can produce magnetic fields simulations on our personal computers....

Dear lesics , We love your videos on electrical devices . Keep on this work ;)

Absolutely beautiful, thank you for this video, it's really helps. Your one of the very few RU-vid channels I FEEL the need to donate too. Keep going please! 💪🏾

I really wanted to learn about motors and windings and this video is awesome. You give way more than anyone else i;ve encountered on the subject. Thank you!

@Lesics When I first began investigating motor and winding design, I was startled to see the interior of a microwave turntable motor, a design I've never seen drawn up or analyzed ANYWHERE despite its extraordinary simplicity. It's simply a small spool of wire, where the ends of the spool are soldered to one of two terminals. These two terminals are soldered to the the positive and negative wires, respectively, feeding power to the motor. There is a cylindrical permanent magnet inside the copper wire coil, and within the cylindrical magnet a gear is embedded. As that cylinder and its gear rotate, in turn it rotates a series of gears that step down the effect of the household current (110V AC in the U.S., of course) such that the turntable within the microwave rotates perhaps 3 to 6 times per minute (3 to 6 RPM). Startling, how simple the design is, and even more startling is why an analysis of this simplest of all motors appears nowhere on the internet or in books on motors---at least not that I can find. It's still puzzling, why the cylindrical magnet turns so reliably in the absence of anything resembling windings or brushes. Can you explain?

You showed us a lot of clear knowledge, like the old technology video… thank you

Thank you for the great effort and work you put to aid in easy understanding. Your work is outstanding. God bless you.

The 24 pole is used in stepper motors aswell. You can achieve very precise control of the rotation of the shaft using a stepper motor control module hooked up to an Arduino/Raspberry Pie development board.

Great explanation of RMF. The animation is very clear. Many thanks!

Unbelievable finally I learned the winding

Bless you and thanks for your explanation and teaching

My motor design class in college was one of the hardest. It was brutal! I vowed never to do that as a career! A year after the course I found myself working as an intern at the Motor Division of Emerson Electric designing the automated equipment to wind motor stator windings for fractional horsepower motors. LOL 😂

Oh my god humanity has gone really far huh. Imagine this is like one of the simplest things relative to all the other creations, and it already has so many things you need to know. Crazy

I see lots of effort and deep understanding of the team made this videos. That is really a great things.

Best video on RU-vid about this, thank you so much for your extremely hard work on this.

Just for clarity, it was Mikhail Dolivo-Dobrovolsky who invented the three-wire three phase electric motor.

Great video with very intuitive graphics helps people to understand the basic of RMF motor. Lucid Group takes the design of induction motor to another pinnacle of power and efficiency.

excellent animation and very clear explanation.

No one gives credit anymore to Nikola Tesla who came up with rotating magnetic fields to drive a motor. So it is amazing that this video does.

Beautiful and clear animation

Thank you so much for making this animation explaining how winding is made .I always wonder. This channel is so important to electrical study. U rocks..!!

Thank you for the videos, and i lowered the speed to understand more efficiently, word by word.

So impressive that very smart people discovored and developed such a complexe system without computers or simulations. They must had a huge imagination.

Very informative, great graphics and crisp narration. Bravo

Outside is the coil field. On the collector there is only a metal drum with deceptive rigid magnets without any particular effect, since the coated three-phase drum also tends to short-circuit this effect. A real local conductor is missing in the drum

Wonderfull content, was looking to an example of the RMF for something I was trying to teach and found this gem.

Beautifully explained 👍🏻

Finally i found what have been looking for..such a vivid description

The animations were really good.

This channel deserves 100 million subscribers 🙏🙏🙏......

amazing engineering lesson sir ,thanks a lot

One of the most awaited videos is out🥳

I understood by every one step at a closer look about AC productive mechanism. Even though I was commerce Graduated. Perfection in the teaching called as in this vlog. 👍I thank you firstly.... Thank you so much for this great wisdom sharing throughout the world. 😜

Thank you, i want to understand coil winding better and this really helps.

I failed to get all of it; but great video. Maybe watching again is needed

This is better than any textbook of electric motor.

Brilliant video! Certainly better than going to engineering school

It's really a helpful comprehensive video.. Explains in an easy and understandable way .. Thank you very much

it's really very educational and informative video .thank you so much

Which metallic wire is used to make the windings in Tesla model s? Is it Copper or Aluminum? Which would be effective? Thanks.

The animations are outstanding!

2:29 says - Tesla didn't develop 3 phase RMF winding!? As You demonstrated in video (excellent BTW), specific geometry of winding produces Rotating Field, invented by Tesla all together with polyphase (more than 3 didn't show economical) and asynchronous motors like consequences of RMF. Rotating Field works on paper and theory with no problems, but motor doesn't wort without windings based on that theory. I;m wrong, or right?

Wow thank you so much!!!! Very interesting and it is brilliantly visualised. I´m here because I´m about to build a more modern stator on a vintage 1981 motorcross bike. The stator plate was missing and they are overpriced on Ebay AND obsolete/ too simple. I want to install a battery anyways so I´d rather build a reliable source of current from the ground up. I just love transformers and electrical motors. I have countless saved and I have a lot to learn still since the technology still is advancing fast.

lovely!! Greetings from brazil!!

Awesome video. Thanks for all your work

I´m amazed with such a great video !

That's a very good explanation.

>7 Million by the year end. Please share this channel with the friends you think are interested in engineering. Engineering is hard, let the students understand, get more curious, and perhaps invent something in future. The least we can do is to share this channel with them. I am sharing with all the students I know.

Very well explained and illustrated..

in a 4-pole motor, the RMF must go through each pole pair twice to complete a full mechanical rotation, while in a 2-pole motor, it only needs to go through each pole pair once.

Super explicación una gran animación Saludos de 🇲🇽

you are the best explanation that I have seen on the youtube. bravo

Howdy, great contents! I'm curious to see if having a means to charge super capacitors within a vehicle, to be discharged after to ride past a certain interval (via the trigger), to then be powering homes and businesses as you drive past... (Peltier devices, sterling engine type, driving to distill the water from the ocean; to then be released into the atmosphere to then water the crops... it would be pretty sweet if it could collect moisture from the air...) Lol To more Blissful moments!

If you could comute the conections with transistors inside the motor, you could control the speed of the motor by making the windings produce a 2, 4, 8, etc. -poled magnetic fields.

Excellent video. Good presentation. Animation at it's best.

I Love You broo❤️❤️You are a genius and the best teacher I have ever seen in my life..

Glad to watching this video clear explanation.

Wonderful video... Thank you so much...

This is a really good representation of the workings of a motor, but I have a question, At 2:37 and at 2:48, you might have observed the, magnetic line direction always emanates from the North Pole but in this case it seems to be the other way around. The image on the top left is correct but the animation is wrong. I may have understood the animation in a wrong way but just wanted to point that out here. Overall I really appreciate the work put in this video. Thank you!

How many "poles" does the motor in the video have? When the number of conductors are increased as shown at 4:15 does this double the number of poles? I've never understood what motor "poles" means. Is it the number of physical slots in the stator, or is it the number of magnetic poles in the rotating magnetic field? It seems to mean different things to different people.

Lots of love for wonderful explanation 💓

Man...you ought to open your own school if you don't have 1 already.thats a perfect explanation u gave there

Clear explains.very nice thank you sir .👌👍😊💐

Finally found an extremely good channel

감사합니다. 불안하고 힘든 시간을 잊을수 있는 시간이네요. 당신의 음악에 거울한번 보고 날사랑하자 웃어봅니다.^^

Thanks for the video. Informative.

Very nice animation. Ive always been confused with motors that can be wired in Y or Delta (you can change by making different connections at the peckerhead) and how that all works

Wow..!!! What an explanation with animations.
