after 5 years of bachelors and 2 years of Masters degree, whenever I forget something I get back to this video, simple and clear and amazing. Wish education at every level is like this
This is exactly the gold in youtube. Problem with induction motor and synchronous motor had been frustrated me for a week and solve in 10 min in this video
Thank you so much for showing how a synchronous motor works. Wayy better than a robot reading text at me like the other videos. We appreciate what youre doing
Thank you sir from the deep of my heart. From the topic synchronous motor one question was coming in my exam. I felt it would not affect if I leave that question. Still before the exam I thought to get basic knowledge about synchronous motor. So I watched your video. And I was extremely happy because I was able to attempt that 14 marks question. Thank you sir. Great support. Keep making educational videos..
I feel like the lack of sentence structure makes it easier to understand. It feels like I’m a caveman and the voice is trying to dumb it down for me. Which is good because me Unga bunga boi
Anyway the physics behind synchronous motor is explained beautifully with the help of animation...ur my science teacher😍😍 keep on making this kind of video
My Online classes has already began and we are studying about synchronous machines..but my professor didn't made it clear..but #learn engineering made it..thank u ..keep posting 😊😊
You guys really do great things. Your every video is great and the animation is just mind blowing. Please never stop, esle you'll made my study really tough.
This is extremely good video I hope anyone should with start with this video before going in depth so that they can resolve all the issues and design m/c by themselves.... Thank you so much Learn Engineering..
This video clearly portrayed the process for me. I was not able to visualize it. Great explanation and even better animation. Hope you bring out more such videos regarding electrical machines. Electrical machines seriously need people like you who make it easy to understand. Other sources of electrical are the same textbook handouts with narration that is hard to make sense.
This is a very nice and informative video.The way the animation is slowed down and simplified only adds to the effectiveness of it. Keep up the good work.
Doing a great job by explaining tough concepts so clearly and neatly with excellent animations... keep doing these kind of things very thankful to you @learnengineering
Everytime #lesics @lesics i forget about Synchronous machine basic principles i tune into this video, within minutes I'm good to continue my engineering career😅🙏 thank you a lot
Was very much confused between this and induction motor and thought why can't this act as induction motor as both stators are excited by 3 phase supply and what was the need of excitation of rotor winding. Now I get it, great explanation .
Synchronous motor is a doubly excited machine i.e two electrical inputs are provided to it. It’s stator winding which consists of a 3 phase winding is provided with 3 phase supply and rotor is provided with DC supply. The 3 phase stator winding carrying 3 phase currents produces 3 phase rotating magnetic flux. The rotor carrying DC supply also produces a constant flux. Considering the frequency to be 50 Hz, we can see that the 3 phase rotating flux rotates about 3000 revolution in 1 min or 50 revolutions in 1 sec. At a particular instant rotor and stator poles might be of same polarity (N-N or S-S) causing repulsive force on rotor and the very next second it will be N-S causing attractive force. But due to inertia of the rotor, it is unable to rotate in any direction due to attractive or repulsive force and remain in standstill condition. Hence it is not self starting....BUT WHY SQUIRREL CAGE SHAPED ROTOR IS USED?
+AJITH THOMAS I believe the squirrel cage bars are affected by the rotating magnetic field (RMF) such that it produces a force which begins to spin the rotor (see 2:46)
It's like someone who barely spoke English wrote the script, then they got a native English-speaker to read it and he didn't care enough to get them to change the wording 😂
I have a doubt..... Because of the three phase supply given in the stator, a rotating magnetic field occurs.The rotor is given DC supply so thus it creates stationary magnetic field around it. Theoretically The stationary magnetic field produced by the rotor should catch up with the rotating magnetic field of the stator thus because of magnetic locking the rotor spins(mechanical energy as output).......but the rotor should have some weight..... right? Is it possible for the rotor to catch up with the rotating magnetic field of the stator because obviously the stator field will be faster than a mechanical object. So the rotating magnetic field "might" complete multiple rotations even before the rotor catch up to it...so the rotor should be Oscillating instead of rotating right....??confusing :|
Yes! In this case, the rotor won't be able to start it's rotation, maybe it will just vibrate. That's why the squirrel cage is used. Listen to the explanation once anain, and you'll find your answer!
Yes. That's why the squirrel cage is placed over the rotor as a starting mechanism so that the rotor speed can catch up with the synchronous speed. Once, the speed of the rotor rises, the excitation is applied to the rotor to achieve the magnetic locking required for the synchronous speed.
1:42 why the number 120? Here in europe we do have ns=60*f/p, where 60 stands for seconds in 1 minute, but cant find anywhere explanation for the 120 in your version.

Please i need your help. My name is Benjamin and I'm very happy to see these video
It's amazing how far a simple animation goes at explaining things.
This is exactly the gold in youtube.
Problem with induction motor and synchronous motor had been frustrated me for a week and solve in 10 min in this video
I don't know why these kind of videos are the standard when it comes to explaining these concepts in university. Great video!
Because they have to pay $ for them
I cant thank you enough for the videos.Made life of a mechanical engineer in electrical world so much easier.!!
th-cam.com/video/OfyLqFJG8Kk/w-d-xo.html
oh man, how comprehensive and crucial this video was for understanding the difference between the two and why it is not self-starting inherently
Thank you so much for showing how a synchronous motor works. Wayy better than a robot reading text at me like the other videos.
We appreciate what youre doing
You have no idea about how many doubts you just cleared!! Thank you.

its science n technology nt english class.. so stop criticizing. . he explain beautifully...
Thank you for your support. We have removed English mistakes in the recent videos.
May god bless your english!!!
no hope for humanity...
Agree with you. Didn't see any wrong in this video. Nicely explained video
abc xyz exactly.
Thank you, you're a lifesaver. I finally understood what's a synchronous motor
Didnt understand anything in class and used to think Bee is very boring but you guys changed my mind.
"slip out of synchronism"! ❤💗
This sentence boils down the concept of slip... HATS OFF!!
I feel like the lack of sentence structure makes it easier to understand. It feels like I’m a caveman and the voice is trying to dumb it down for me. Which is good because me Unga bunga boi
Hello another unga bunga mam i feel the same
i love the broken English combined with a perfect Midwest accent lol. the video still gets the information across
He's a busy guy, he doesn't have time to waste saying the word "the".
Don't give them credit- It is exploiting ethos and while the logos is there... the whole video is not totally there.
@@DigitalAndInnovation can you elaborate, just asking 😊😅
I can't explain even in words how useful ur videos are..
Keep it up❣️✨
Anyway the physics behind synchronous motor is explained beautifully with the help of animation...ur my science teacher😍😍 keep on making this kind of video
Physics Lover yea, well done.
My Online classes has already began and we are studying about synchronous machines..but my professor didn't made it clear..but #learn engineering made it..thank u ..keep posting 😊😊
Whoever came up with the idea of putting a squirrel cage around the rotor is an absolute genius.
Your Videos are genius, help me understand the subjects so well and only in less than 5 minutes. Your are life savers! MIT is not better than you!!
You guys really do great things. Your every video is great and the animation is just mind blowing. Please never stop, esle you'll made my study really tough.
Finally found the simplest and clearest explanation.
Thank you! You solved in 15 min. lots of question I got in the last 3 hours classes.
This is extremely good video I hope anyone should with start with this video before going in depth so that they can resolve all the issues and design m/c by themselves....

Now I get it, great explanation .
This is a documentary of his two friends Motor and Rotor.
Yeah, I found it informative, but he just couldn't use "the"..at all..
oh than fuck it wasnt just me. its weird right.
yes yes of family form from generator alternator motor rotor _arch lord
Codependent enablers, yet polar opposites.
Great information. Good for the old ,iq

+AJITH THOMAS I believe the squirrel cage bars are affected by the rotating magnetic field (RMF) such that it produces a force which begins to spin the rotor (see 2:46)
I believe this cage turns this motor into a induction motor and causes intial start
I think, the SQUIRREL CAGE is not needed. The DC power supply to Rotor or a parmannet magnet will give push to start the rotor to move from inertia.
Thank you for a Superlative easy to understand explanation.
Superb explaination within few seconds
awesome explanation & animated.very much helpful to understand the basic idea of synchronous machine.
Great explanation. Learned about sync motors.
Thanks a lot man
May God bless your channel 😇
This video was very helpful, thank you
My tutors don't even bother anymore lol; they just post link such as this one all over the place...Welp get's the job done :

So... Grateful to ur channel, concept soo... Easily explained
Nice animation and well explanation good job. (India)
the best explainantion for synchronous motor. Excellent Sir
excellent explanation and animation sir
Ur narrations are superb...keep doing it @learn engineering
YOU ARE DOING A GREAT JOB !!!!
It's totally awesome video..... explanation is very clear and detailed. Great job!!!
It's not ok to call the stator coil a field coil in this case 0:33. The "field coil" is in the rotor. Be careful. The motor gets upset easily.
Absolutely right
Very informative. The animations help too. Thank you! Although, it's okay to say "the" more than once per video. xD
It's like someone who barely spoke English wrote the script, then they got a native English-speaker to read it and he didn't care enough to get them to change the wording 😂
Your all video are really great ......
It is most useful for learning engineers,how is possible ? it is amaging to me.thanks for utube.
Perfect explanation ❤
So many equations it’s helpful to actually know what’s happening
U got a new subscriber 🔔
nice lecture and operational features.
very good
I enjoyed
Always be on top and successful
please make some more videos of electrical machines you explanations are very good
Very good your explanation is so high level ..... Keep it up iam with you sir best of luck and iam waiting for your next video
