Understanding electric motor Windings!

It’s a pleasure to watch fabrication process of windings in the factories. What you see here is a fully automatic winding process. The windings take in electric current and create a Rotating magnetic field out of it. This RMF is responsible for the motor’s rotation. You might be curious about how this Magnetic field rotates even when the windings are stationary? Let’s unveil its working, come along!

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 an Electrical Engineer. I like how I still awe with the technology and applications of Electric Motor Windings on our everyday life. You just did a certain and clear illustration of how magnetic field works depending on the design of the winding and how variations on number of poles are important depending on the purpose of the Electric Motor.Thumbs up Lesics all your informations are top notch, accurate and informative.

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.

[lawtonsegler]

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.

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.

[NAYAN-te]

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

[snow]

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

[AngadSingh-bvvn]

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

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.

[aaronhoffmeyer]

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.

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

[weiang]

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!!!

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.

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....

[GururajBN]

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.

[sierravortec]

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

[nithiphatteerakawanich]

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

[cayezara]

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!
