Have you seen anything of sphere tires. Goodyear prototyped one that i knew of in 2015ish time. Would this be a logical was of manipulating a weight or some sort of mechanism to propell a ball or sphere in goodyears situation?
Best tutorial on RMF's for me by far. On a philosophical note, this video created sometimes in 2013 is still helping people 9yrs down the line. Amazing 👍👍
Thanks! Best explanation about the rotating magnetic field. I am from not electrical background and I hated this concept but now I have a clear understanding of this concept. Cheers! Thanks mate! Keep it up!
Thanks for the feedback dlna4D, I fully understand your point. My plan was to do another video specifically on the induction and synchronous motor. I will get around to it, but I've promised to do one on generators first.
The 90 degree phase difference at the start is a property of a two phase supply. If it were a three phase supply, the phase difference would be 120 degress. I'll do a video on AC generation within the next 12 months if you wish. Thanks for the feedback.
Sorry...I'm a bit lost here ( not an expert.....just trying to get my head around this) .....from where is the 2 phase supply coming from? In the UK we have a Single Phase Supply....am I right in assuming this is a Start and Run winding config?.....or split phase ? .gratetful for any guidance 🙂
@@robinfrancis789 This video was only for instructional purposes to show how a rotating magnetic field can be achieved. In the UK, domestic electrical supply is single phase and industrial supply is three phase. To obtain a rotating magnetic field with a single phase supply, a capacitor is used to split the supply into two phases, 90 degrees apart, as depicted in this video. I have another video that tries to explain how the split phase works. You can find it here: th-cam.com/video/pbg_PF6MTwY/w-d-xo.html
Sir I'm from India I was searching for this type material of machine since one month and I got awesome video of yours. very good and understandable video u have made... salute sir।
This is a good explanation of flux rotating with the current movement. I'm here because I bought a book on Tesla's writings.. I only have a pre-app in electrotech so I've next to no background.
Really great video, you helped me to actually understand what is going on rather than just be able to prove it with formulas. Much of the time the math obscures the basic ideas of what's really happening, and you've really clarified the ideas well.
It was you pouring it into my brain without any hindrance... absolutely fantastic...would love to see more of these videos. Doing awesome...keep doing more.
Very well explained. One point; the magnetic flux lines generated by phase 1 and phase 2 are separate fields and when you find the resultant, then it ends up with one magnitude and a direction that you showed. Additionally, if you increase or decrease the frequency you increase or decrease the speed (RPM) of the motor, and if you increase the number of pole pairs, you get the capacity the have more current draw and so resultantly produce higher torque. As I read on Quora; frequency is speed, current is torque, and voltage is the capacity to create torque.
Wow... finally a useful video! Long search, but worth the wait. Now if only he would have explained how the hell one is to do all this reversing of the magnetic fields and what not...I'm assuming there is a component needed between the power source and the motor, I just haven't a clue as to what it is.
What a great description of rotating magnetic field..... Loved it.... Really awesome.... I guess you are a professor... If not then you must become....world needs people like you to teach upcoming generations.
Thank you. This is the best video about magnetic flux inside single phase motor for me. Спасибо, это лучшее видео про магнитный поток в однофазном двигателе как по мне.
06:56 I think the physical magent put inside will be upside down, as the North attracts the South and vice versa. Take number 1 position, for example, when the rotating magnetic field of the stator is North, the South pole of the magentic bar will face it(the blue color).
If you look down through the comments you’ll see plenty of discussion about that point. In short, if you hold a compass in your hand, the needle with N on it will point North as it is a North Seeking Pole, as opposed to a North Pole.
Excellent video; it really helped me visualise the magnetic field inside AC motors. However, I noticed that the rotating magnetic field and the magnet have the same poles facing each other. Shouldn't they be opposite so that the magnet's S pole follows, or is attracted to, the rotating field's N pole?
That is why I said one is a North seeking pole and the other is a north pole. On a compass, the north seeking pole (with N marked on it) of the needle points North. The same thing here.
Love the way you broke it down pretty simple I actually kind of get it. Only thing I would say is speak more into the mic, seemed like you were far away or with a low voice I mean so you could be heard better
Hi Sal. I fully understand what you're saying but what the textbooks tend to show is the North Seeking Pole on the magnet (i.e the South Pole) following the North Pole of the Stator. So I've followed that format, i.e. the pole marked 'N' on the rotating magnet is really a North Seeking Pole i.e. a South Pole. This is exactly as you suggested. Thanks for the feedback.
Very helpful video, thank you! One question follows: In the first 40 seconds you show phase 1 current flowing through two coils, one at the top and one at the bottom. You then treat the two coils as one, or so it seems. Doesn’t each coil have a north and south pole? It seems to me that flux from the south pole of the upper coil would wrap around the stator and “connect” to the north pole of the lower coil. Thanks, again.
The two coils are wired in series, and yes each will have a north and south pole. The wiring has to be such that the direction of current in one coil is opposite to the direction of current in the other. Using the right hand rule, if your fingers point in the direction of the current, then your thumb will point in the direction of the North Pole. So, if you want the poles to point in opposite directions, then then direction of current will have to be opposite.
I've been looking at a lot of AC motor animations as this is one of the best. Could you be persuaded you to a) make a 3 phase version, and b) add a part about how they currents are induced on the rotor. The 3 phase motor is getting talked about more and more in electric car circles like with Tesla, and avg. drivers are trying to educate themselves.
so we can name this"resultant rotating magnetic field" in single phase motor this resultant is zero at starting so we need auxiliary winding to star the motor .....right?
well described video. It's clear information and enough to get principal rotating magnetic field. By the way, how can we set north and south using current direction? what's the parameter to get north and south reference in stator?
Great explanation. But I have one doubt- Shouldn't the bar magnet shown at last have opposite polarity? I mean north of bar magnet should be attracted towards south of magnetic field and vice versa...
Ok, think of it this way. When you hold a compass doesn't the needle with 'N' on it point towards the North Pole? It's the same here. The N on the rotor is a North Seeking Pole (i.e. a South Pole) just like a North Seeking Pole on a compass.
You're welcome. I'm delighted that it was of some use and your positive feedback will encourage me to do some more. Thanks for that.

Fantastic video Roddy! I am studying AC/DC motors and this is by far the best ive found so far!
Thank you so much man. The video is done perfectly. Simple, interesting and visual. Much needed, thanks again
Excellent explanation, very easy to understand, thanks
This is awesome! The Physics of motors is really intriguing.
I was shocked, amazed how this guy can explain very simple compare to any other channel who doing the same subject
Thanks a lot ... Finally had all my doubts regarding rotating magnetic field cleared! Really awesome.

Thanks Sir, i got the concept behind rotating magnetic field
Omg! Best explanation ever! This is what I’ve been looking for thank you🙏

@@RoddyMcNamee that's because the magnetic south pole is at the north.
Clear and easy explanation! Great video, thank you very much!
thanks so much! the best explaination i have ever experienced!
thank you very much I was wandering like this rotary field but now i learned it from you
First time I understood with such a decent explanation thank you sir god bless you
you have made this really easy to understand...thanyou !!!
Excellent video; it really helped me visualise the magnetic field inside AC motors. However, I noticed that the rotating magnetic field and the magnet have the same poles facing each other. Shouldn't they be opposite so that the magnet's S pole follows, or is attracted to, the rotating field's N pole?
Okay, I figured it out from watching your other video. You refer to the magnet's poles as "North/South seeking poles".
7:13 like pole repel, unlike pole attrack, it should follow the rotating field with its opposite polarity
That is why I said one is a North seeking pole and the other is a north pole. On a compass, the north seeking pole (with N marked on it) of the needle points North. The same thing here.
best explanation , i have ever had. Thanks Sir
Magnificent explanation. Thank you!
Love the way you broke it down pretty simple I actually kind of get it. Only thing I would say is speak more into the mic, seemed like you were far away or with a low voice I mean so you could be heard better

so we can name this"resultant rotating magnetic field"
in single phase motor this resultant is zero at starting so we need auxiliary winding to star the motor .....right?
Yes. In a single phase motor you would need an auxiliary winding to start the motor. I have another screencast on starting a single phase motor.
@@RoddyMcNamee thank you
This is for RMF utilizing coils how about utilizing windings? Can you make a video for that?

Why is the magnet's north pole is not towards the south pole of rotating field?
Aren't V & I only max at the same time in a resistor? Wouldn't these coils be an inductor?
Well understood Explanation
