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.
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.
Thank you for typing this so I didnt have to. Video tries to give Tesla all the credit and then puts a little note at the bottom saying it wasnt him... SMH
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!
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.
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....
The explanation and graphics are superb. As I gather, the more the coil windings, the better is the torque and more uniform the delivery of power. I have to watch this video again to understand the explanation better.
The more poles you have the slower you can run the motor to get the same degrees of separation... which also results in higher torque for the same windings if it weren't. Also the thickness of the windings... the more copper the stronger the field but then you have cost and weight and size for the application. Then you also have to deal with eddy current losses and how to minimize through plate design, laminated plate thickness, etc. There are advances for the same size motor getting more power gping on... but it does scale pretty linear... so the more power needed the bigger the motor.
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 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.
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.
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 :)
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.

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.
@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?
Hats off to your work and dedication this video is not only for 2020 generation it's also till the 2050 generation, as like HC VERMA PHYSICS BOOK inspite of no new edition( more that 30 year old book) it will shake your l. Respect to your work 🙏🙏🙏 You are a true engineer. I am also a Engineer and physics lover but but Right now I am just e employee in a Engineering company.No use mind just go this your boss suggestions #prectical suggestions.
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?
It was Arago who discovered the Rotating Magnetic Field theory, not Tesla. The two phase or three-phase motor was also not invented by him, rather Ferraris and Dobrovolsky. It's often misattributed to Telsa because of the term 'polyphase' and as he was the first to patent the two-phase motor, but this was two years after it was invented by Ferraris.
>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.
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.
Can be either or. You are always going to have two magnetic poles as you need the field to rotate. You don't want to cancel your magnetic Flux by creating opposing fields. But you might add poles to makes a stronger field like in the video but there's still only 6 poles as they're still rotating 120 degrees out of phase in one cycle. Now if you wind it such that those 12 poles alternate, then it'd be a 12 pole motor because it'd complete two hertz in one revolution. A 3 phase motor should have a minimum of 6 poles.
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
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.

Excellent video. Good presentation. Animation at it's best.
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.
Can be either or. You are always going to have two magnetic poles as you need the field to rotate. You don't want to cancel your magnetic Flux by creating opposing fields. But you might add poles to makes a stronger field like in the video but there's still only 6 poles as they're still rotating 120 degrees out of phase in one cycle. Now if you wind it such that those 12 poles alternate, then it'd be a 12 pole motor because it'd complete two hertz in one revolution.
A 3 phase motor should have a minimum of 6 poles.
Glad to watching this video clear explanation.
it's really very educational and informative video .thank you so much
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
Wow..!!! What an explanation with animations.
Clear explains.very nice thank you sir .👌👍😊💐
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.
I am mechanical engineering, Lesics is beautiful animation and clear to get knowledge level
