Very very clearly you describe what happens in the electric. AC motor. You are very good teacher. I completely understood how ac motor rotate Thank you very much
I had been fixing a multitude of these thingies for almost 40 years and this is the very first and only time I completely understood how the heck it works! The BEST ILLUSTRATED explanation tutorial I'd ever come across!
Finally a real explanation of induction motor working with mind-blowing animation. You are the really good professor not mad 😂😂(u'r real gem)! Please make a animation video on difference between induction motor and synchronus motor.
I wish I had access to such content during my engineering course. The concepts are abstract and need 3d imagination to get into clear pictures. Only words never give justice to understanding the concepts of electric/magnetic principles.
I’m setting in my living room using a fan exactly like the one in the video to keep cool… except mine does not have a Prof Mad starter capacitor. 🤣 Great job explaining everything. 👍
Very good ! But you should describe interference of 2 main flux perpendicular each other and phase shift 90o to create out rotation magnetic fields on stator !
Very Informative videos, and Can you make a video on Star and delta connection, how there are different to each other and how voltage and currents are calculated, using animation. Wating for your videos, Thanks!
In asynchronous motor the rotor will never spin in same speed as the magnetic field. The rotor will always rotate slower. In zero load it will almost spin as fast as the magnetic field but that speed will decrease with increased load (slip). The magnetic field rotation will always be constant if the AC frequency will not change. Still very nice video.
Thats interesting. I recognized that if I run the fan without blades the speed of all 3 steps seem to be the same. So the speed must vary through load and current changes.
Yes, with more load on the motor shaft.. more slip happens, and more current is induced in the stator, and so more tor torque is developed, to try and balance the load.
@@Savan_Triveda With those cheap fans, the motor's field coils are not wired so that they must all be taking current. The field coils have individual wire leads that can be used to switch pairs of those coils in or out of the circuit. (That's what the switch is doing.) Switching out pairs of coils changes the number of powered poles. Less powered poles, means faster speed.
Good video. But, actually, the magnetic field in the stator coils does not actually rotate, in the same way as if you were to put an axle though the center of a bar magnet and rotate it. We only infer continuous motion, the same way we infer the motion we see in arcade lights. We see continuous, even smooth, movement where there is none.
@@brlinf06398 Have you dismantle a table fan before? Inside don't have any complicated electronic to change the voltage at the switch. The switch wiring just straight into the motor coils. I guess the inductor motor inside have 3 different speed coils for 3 different speeds, switch by the switches.
@@RowdyRana-zc5gl Spelling, not grammar. Those who denigrate spelling and grammar are ignorant of those things and want the world to partake of their ignorance.
7:16 incomplete information, you didn't talk about synchronous speed vs rotor speed Difference or slip it's very important because rotor only generate it's won current and rotation Magnetic field because of relative motion between Stator rotation magnetic field and rotor conductor bar but once its rotor reach to same speed of rotation magnetic field RMF there is no relative motor or flux change in rotor conductor so it will loose it's current and RMF SO, but it never happen with This induction motor rotor speed is always slightly less than RMF called synchronous speed this is called slip.
I have a Question. I have an old 12v motor from my van's rear bench seat that folds down. It has 2 wires that come out of it that gets its power from the car. How can i take it appart and add 2 more wire's so it can be use to get power and give power at the same time.
it's totally wrong about how INDUCTION motor working. In your video, rotor speed and rotating magnetic field speed is the same. It's totally wrong. The speed of rotor is always lower than speed of rotating magnetic field.
please stop using ai voice, i instantly closed the video after hearing it cause its linked with low quality content, but I gave it a chance and the video is a actually amazing so please don't waste the potential value of your videos with those crappy ai voices

My doubt has been cleared now. Thanks for your explanation and animation.
Happy to help
Finally understood how the capacitor changes things . Thanks !
Great videos and very good channel !
The Best Illustration... Thak you, from India
Very well explained. I'm not a technical person, but I could easily grasp the technical aspects. Thank you 👌🎉🌹
Excellent explanation. Thanks. 👍🏻
Excellent video on the generation of a rotating magnetic field from single phase supply
Super Sir.
Very well explained.
Thank you very much.
❤❤❤❤
Good video.
Just don't forget the thermal fuse for protection.
Thank you very much, this video explains the working of an electric motor clearly.
Thanks for watching!
Great explanation
Glad it was helpful!
very useful information first time I have understood so clear
It is very clear to understand how a fan operate.
Thank you for this useful information❤
Very good eplaining for a beginner like me!!!!
That explanation was literally insane! I guess that's why you're called Professor Mad. And I thought it was because you were angry. 😁
Best explanation and video ever👍
Abosuluty wonderful. Thanks
Our pleasure!
Eu aprendi mais com tua explicação, do que com 4 anos de Engenharia na Faculdade.
Best explanation ever
I learnt from this video on single phase induction motor
keep up the good work 👍
Sir, thank you!

Amazing work! The level of detail in your animations is incredible. Could you share what software you used to create such powerful visuals?
This is the best way to learn! For me anyway.
Glad to hear that!
Excellent!
So nice thanks sir
Nice job
thanks for the great video.
many of those have 3 state mechanical switch for speed control, It would be great if it is explained as well.
I’m setting in my living room using a fan exactly like the one in the video to keep cool… except mine does not have a Prof Mad starter capacitor. 🤣
Great job explaining everything. 👍
Thank you 🙏
Thank you.
Thanks so much
Thanks, very good interpretation. --- from India.
Great Prof. Curious to know how the efficiency vary between Stand fans vs Ceiling fans...
Very good
Very good ! But you should describe interference of 2 main flux perpendicular each other and phase shift 90o to create out rotation magnetic fields on stator !

these are 3 phase
Thanks sir.

He didn't tell about concept of the difference between synchronous speed vs rotor speed and slip.
How does it control the rotational speed of the rotor through the switch?
How to select the capacitor for the stator winding?
நன்றி 🥰
Please note that conventional current is used here. Actual electron flow is in the opposite direction.
super sir

Please how do you do the animation used in your videos?❤
Thanks, but can explain further how the table fan 3-speed change speed?
this is why I hate induction motors, its speed depends on load. Ok so the answer to your question is, it changes its voltage

6:55-7:13 There is no "e" in "rotor."
8:16-10:30 "Ammeter" has a double "m."

replace one m to p
Thumbs up!

I was suprised the first time I know there is motors that use induction
But what happens when you press the buttons to change the speed of the motor?
That cause the current flow changes
👌
I am mad on your videos
ehat???
it's totally wrong about how INDUCTION motor working. In your video, rotor speed and rotating magnetic field speed is the same. It's totally wrong. The speed of rotor is always lower than speed of rotating magnetic field.
This is an illustration of what is supposed to happen. It's not the real physical thing operating wlc will include friction and imperfections.
It must be wrong, otherwise so called conspiracy teoretists would not exist
Listen well. He said the rotor is always trying to catch up with the field from the stator…
It means that you are watching the video awakening, which enables you to find the deficiency in an explanation of an important concept.

I never really never found fans fascinating.
