this video has helped me through my undergrad and now at postgrad. Great work Prof. Umanand, NPTEL, Indian Govt :)

[@iam4akhir]

Wow we don't need to go all the way through texts. Just need to watch these vids a couple of days b4 exams.. :-) A very versatile, in depth and above all very useful video series... Thanks a lot 4 the upload. "It is good people who makes the world a good place".

[@technoturko]

Thank you very much..!! This video lesson is great. I from Turkey. My department is electrical engineering. I didn't understand from my teacher but now, I understood induction machines. Again Thanks..!!

[@Girishkrc]

Amazing lecture.I am a fluid power engineer and i was always confused about 3 phase supply and induction motors.hats off to Mr.Umanand for teaching a complicated subject in a easy and understandable way :)

[@johubify]

hello sir I see this comment was made a long time ago. How is life now?

[@antonvella2647]

well done and very well explained. no unnecessary detail and lecture takes you through each step in a systematic way. the sequence makes perfect sense. well done sir. Im a fan of yours

[@h.bknowledge7891]

Bro can you tell me wheather a 3 phase motor needs running winding or not?

[@ninjasdoitbetter]

Thanks -American at the very respected electrical engineering department at the University of Colorado at Boulder. Thank you.

[@phanidharkumar7007]

For someone like me who has a basic understanding of network theory and who wants to know about induction motor , I can say that you won't find a better lecture than this.

[@soumyajitdas771]

Sir. thank you for such a clear explanation of the fundamental concepts. it was really enlightening

[@rakamal2007]

these videos (particularly induction motor lectures) helped me in developing an interest towards electrical machines. thank you very much

[@chaitanyarao9262]

The book referred is Principles of Electrical Machines and Power Electronics by P C Sen. It's a really good book.......

[@baltakatei]

At 22:30 he got the direction of current wrong. Be sure to look up the correct relationship between magnetic field (B), current (I), and induced Force (F).

[@schniz2]

Excellent lecture... perfect speed for my slow brain, love the neat diagrams and thorough explanations... thanks!

[@theoryoverload8237]

I am from iit and i find this teaching far better.

[@MrSauce714]

probably the best material online for learning power machines, thank you so very much !!!!

[@AmitKumar-xv9lq]

This is the nice lecture to clear the basic principal of induction motor.

[@rickey5353]

Thank you for a very clear explanation. Now, after viewing this lecture several times and jotting my own rendition, I might begin to comprehend this process.

[@bunberrier]

Thanks for sharing your knowledge with me. Your presentation is excellent!

[@m4fiaafg]

very good lecture, very clear and slow, thank you for shgaring this, keep it up

[@swatheeeee]

actually great PATIENCE is needed to watch this video though it's INFORMATIVE.can speed up the loading process....................but anyway video is much informative ,concepts are explained by you well sir.thanks a lot sir for sharing this video with us.

[@vedantwankhede7481]

sir , a million times thank you..and the rotating magnetic field explanation was really awesome

[@tulsEE87]

THANK YOU SIR FOR GIVING SUCH A VALUABLE LECTURE...CLEAR EXPLANATION

[@surender7212]

Sir please answer that in these here if two phase are connected here so that there is two dample of same polarity like south and south , North and north but in one cycle there is change of polarity will maintain . Induction motor introduction 40:33 minute.

[@mak5386]

Sir,every topic was precisely explained .Thanks a lot !

[@superdudeee2345]

All my doubts were cleared sir....very nice lecture....

[@sripradhaiyengar9980]

it's an amazing video... the speed is perfect if one wants to take running notes, if not .. well... I used the right arrow to fast-forward the video when he was drawing :P thank you!

indeed a great teaching! thank you from Brazil!

[@thiagohcosta]

Its amazing video ... I studied this ... and this helpfull for me ..... thanks a lot... From Brazil

[@summerha8170]

22:00 Is the direction of Current I is incorrect? From Faraday's law, the induced EMF should make the current out of the paper direction, For an Anticlockwise rotating B field.

[@nahidhassan179]

35:28 i could not understand how 60/(1/f) introduced?

[@snigdhsinha2246]

@22.10 in the lecture, the notations for the Fleming's left hand rule mentions force being represented by the middle finger, but conventionally the middle finger represents the current direction in this rule. Can someone explain this to me?

[@AhamedAnaz]

thank you very much sir. its really great!!!!!!!!!! i need your lecture for special machines too.like repulsion motors, hysteresis motor,etc

[@rd-tk6js]

very clear explanations, thanks !

[@Caleidus]

@TributeToTesla The supreme court was not called upon to give a decision regarding the paternity of the radio invention and the judges never put in doubt the primacy and the originality of the first complete radio system built by Marconi, and they never stated that Tesla or others invented the radio and not Marconi 2) This what the judges said: “[…]Marconi's reputation as the man who first achieved successful radio transmission rests on his original patent” and “[..]

[@Caleidus]

“[..] To find in 1943 that what Marconi did really did not promote the progress of science because it had been anticipated is more than a mirage of hindsight..

[@Asifcz31]

nice style of teaching... thanks ..

[@AChamp35]

22:00 Sir flemings left hand should be used with Force as thumb, fore finger as field and middle finger as current ?

[@pamartyhimaja6315]

Awesome teaching sir. But ive a doubt. How can current be induced in a stationary conductor

[@themotivated6984]

Isnt it possible to increase the frequency of the line using power electronics?

[@88Ghillie]

Thank you very much sir, now please..have a glass of water!

[@prabhatmishra5667]

from which country you belong bro?

sir, have no words no express ma feelin ! ty !

[@TSIRHCSEVAS]

i have an induction motor. i want to replace/adapt the impeller to a bigger one therefore i want to extend the length of the shaft. my question is: is it possible to weld another 4cm piece to the shaft in order to extend it? please any comments will be appreciated.

[@knightbrolaire526]

Perfect illustrations and explanation! Thanks a lot!

[@basupatil7888]

I completed be with first class and I think know I am started learning.thank you sir you made the concepts so much easy to understand.

[@ShubhamSingh-ld8so]

flaming hand rule is wrongly shown by sir 22:00

[@TonyLing]

Shubham Singh Flemming's left hand rule is incorrectly referenced by you sir.

[@vehicletechnology3704]

a) he uses his left hand, but also explains incorrectly.

[@sujamahmudasad8548]

thank u sir......may ALLAH reward you.

[@hiteshnigam7312]

beautiful explaination :):):) just one doubt. When the we start the motor there is no current in the conductor. as current is 0, so how Lorenz force will act to rotate the rotor???

[@prakharpandey2146]

actully ,when we start the motor, a very high current flows due to high slip(s=1),which is five to six times in magnitude of full load current, which can cause many problems in motor,althuogh it is self starting motor, Starters are used in squarrel cage induction motor and external resistance is used in rotor circuit in case of slip ring type induction motor to increase starting torque and to reduce starting current..

[@chinthutb]

very helpful sir.. thank you very much.. from sri lanka

[@CharanleenKaur]

oh this is 3 phase... thanks a trillion for this sir....and u are great indeed !

Sir, is it three poles or six poles ?

[@ZainAli-lb4qo]

very good thank u sir......may ALLAH reward you

[@youmah25]

ramadhan karim

[@pradeepchotu]

thank you... my que is that.. why 3 phase current apart from 120 degree..each phase lag 120 degree from other phase and 240 from other phase..

[@magicmaxliu]

He is actually better than my professor :-)

[@crazymalani]

Nice explanation...cleared many doubts :)

[@sebascarra]

what software is that?

[@SeedMayers]

thank you for sharing your wisdom, greetings from germay! :-)

[@SKCSK792]

EXCELLENT LECTURE .. thank u sir

[@amarnathmishra1461]

You are a gem,

[@isankoboy]

Sir, you are a genius.

[@himaloyshadhin9958]

clear,everything iz clear now

[@theq4602]

So if I built an induction motor and I wanted it to have the most torque possible I would need to make the rotor chok full of copper conductors.

[@psen2009]

Respected Sir Thanks for your time and the great lecture! I am looking for some help on Induction generators. Is there any lecture module on that ?Would be great help. Regards

[@johncena8336]

which book is he referring to??
