Rotating Magnetic Field

Rotating Magnetic Field in the 3 phase Induction Motor is self rotating by its virtue.
Kindly consider a change in current direction through three phase winding. Cross(❌) indicates the current inwards i.e., away from you (in to the board) and Dot(.) indicates the current outwards i.e., directed towards you. Regrets for having quoted reversely.

[@kanaktandon1573]

He explains in a very very simpler and tempting manner 👍 ... Now I understood RMF ... thanks

[@patakotisrinivas1918]

Superb explaination sir..really easy way to understand...thanks a lot...

[@derickmhlongo6399]

Thanks for spreading such critical knowledge. You are very good. The magnetic field strength pulled me towards subscription key

[@arunkumar-sq8sj]

sir after long time I cleared about this topic , thank u very much sir, ur teaching way is best.....

[@princedavidson5624]

Great effort; excellent lecture; made concepts clear; thank you, please continue this

[@souvikdasgupta6363]

A very good explanation.

[@manilalramanujan5022]

what power full lecture......grate lecture eved ever.....hatts off you respect....

[@meditatewithjcool.9939]

What a splendid presentation❤

[@learnwithus-electricalengi7390]

Glad you liked it

[@sairashmitha1249]

really, it's happy to listen to the detailed explanation of rmf

[@MrShooter8899]

Very simply explained! thanks sir!

[@s.manzoorbukhari3004]

Plz keep uploading videos,your such a talented person

[@learnwithus-electricalengi7390]

Thanks for your words dear. Yes, I will be uploading videos in the next week. Tq

[@s.manzoorbukhari3004]

I wish your 100's of topics to be uploaded like this...outstanding

[@learnwithus-electricalengi7390]

I will try my best

[@malikuzair9947]

Well done sir,nicely explained.

[@sultansaifuddin9969]

This is so good sir,very simple and more logical.thank you sir.

[@hruthviknarayan5269]

Thank you sir for explaining this concept

[@pcpandey2059]

Mind blowing sir..very rarely explained concept..

[@pyramanjaneyulu6251]

simple way of understanding concept. super sir

[@avenkatamahesh3296]

The notation for current coming in and out is opposite to normally used notation in textbooks.. it makes me confused. But the concept is good.

[@ramukorra157]

thanks sir,i really satisfies with your lecture

[@guariba63]

Thank you very much, from Germany.

[@brijeshkumar3908]

Very very nice sir.

[@learnwithus-electricalengi7390]

Many many thanks

[@kalpanameena7112]

Thanks a lot for this

[@manisawhney1882]

Thank yu sir , at last I can visualize it

[@vinr1187]

Amazing.

[@learnwithus-electricalengi7390]

Glad you think so!

[@suhansravs324]

super explanation

[@yashbharadwaj4684]

How can someone dislike this ? Probably the professors who like to complicate things. Please make more videos

[@creativeplanet2147]

Thank you sir

[@jitenderverma1463]

Your way of teaching very good

[@subhrajyotipal356]

Excellent sir need more videos on 3ph im

[@taksh4227]

SUPERB

[@naresh.damera]

very clear explanation. But did mistake in symbols of direction at current flow. dot shows current is coming towards u and cross mark indicates current is going inward or away from u.

[@learnwithus-electricalengi7390]

Dear thanks for the keen observation, the lecture is more focused on the concept of RMF, rather than the current and symbol. I appreciate that.

[@Akshay-zd3ox]

Awesome

[@learnwithus-electricalengi7390]

Glad you think so!

[@vyanketeshmishra3832]

Superb explanation.....👍👍👍

[@learnwithus-electricalengi7390]

thank you dear

[@pallaganiusha8048]

Tq so much sir

[@prasadksr6459]

simply superb...

[@niazislam5745]

Excellent...

[@sathishlakshmanan9317]

your explanation is super sir. please add video related to transformer function and different types of test

[@learnwithus-electricalengi7390]

Will upload soon dear

[@apurvmj]

Normally dot means current coming out and cross means current is going in.

[@learnwithus-electricalengi7390]

Yah you are right, mentioned about this in the description of the video. Thank you

[@shivasaiforyou-basicelectr1790]

Sir if phase sequence ACB( RBY) then RMF rotates in anticlockwise direction , this also explain in the vedio sir for two instants This vedio explains in ABC( RYB ) phase sequence. Which rotates RMF in clockwise direction.

[@akankshaparida25]

Awesome sir ji

[@Innocente1994]

Very interesting lecture... Sir may you make video lecture for armature reaction on synchronous generator

[@pk-saha1817]

Super sir

[@pronabbiswas1454]

thanks for nice explaination sir

[@sandeshshetty8221]

I got it

[@yellowart7814]

Upload videos on power electronics

[@sushilrai1548]

Thank YOu !!

[@taksh4227]

PLEASE MAKE A VIDEO ON HOW TO IDENTIFY NUMBER OF POLES.

[@jaypandya8629]

superb

[@vasamsettisrikarsai6728]

Sir please upload videos on special motors

[@anujpatel2970]

Sir plz share competition question answer regarding railways or ssc jee

[@jaypandya8629]

Sir can you make a video on how 3 phase and 4 pole induction motor work,! Please.... Because I am not able to get to know about how 4 pole are created.

[@lukewestlake]

Did you calculate the speed of rotation of the magnetic field axis of the entire electromagnet by using a wavelength of 60Hz?

[@learnwithus-electricalengi7390]

Appreciate your query, thank you: Speed of RMF at 60 Hz solely depends on the its equation i believe.

[@madagalaharivardhan9412]

The current notation of cross dor is wrong..... current going inside the board is cross . current comming out of board is dot...... Pls reply for clarification

[@learnwithus-electricalengi7390]

yah you are right dear, but the lecture is focused more on detailing the directions of three phase currents and its effects in contributing to the rotating magnetic field formation in three phase induction motor, but not on the notations. The same point is clarified in one of the replies given against the comments down. Hopefully you got me.

[@madagalaharivardhan9412]

Yes sir I got it.At first I also thought that you did not kept focus on that area. thank you.

[@jaypandya8629]

Sir one more question and that is, at 60° the Ic is getting zero!! Isn't it?. And sir at 30° how did you consider Ib as negative and Ic as positive? Hopping a quick and positive response!!

[@learnwithus-electricalengi7390]

Yes dear at 30 Ib is positive and Ic is negative..check the supply voltage wave forms for confirmation.

[@jaypandya8629]

how did you say 30 degrees is 1.6 miliseconds , could you please explain it......

[@learnwithus-electricalengi7390]

If supply frequency is 50Hz, Time period (T) of Supply wave form = 1/50 = 20msec = 0.02 sec. Supply AC Voltage takes 20msec of time to finish its full cycle i.e 360 degrees. So, we consider calibrate time with degrees as, 20msec = 360degrees , there by 30 degrees = 1.667msec, 60 degrees = 3.33msec, 90 degrees = 5msec asn so on. Hope you got it.

[@jaypandya8629]

Thank you for your quick response

[@masoomahmed9348]

Jaanwar aaya. Jaanwar aaya.

[@dhanunjayk7590]

Based on IEEE current coming out taken as dot notation

[@learnwithus-electricalengi7390]

Dhanunjay K .. thanks for the inputs... Appreciated. 😃

[@saurabhyadav2085]

As per arrow notation for current.,u r telling it in wrong direction.. Kindly correct

[@learnwithus-electricalengi7390]

thanks for the suggestion, i have mentioned the same in the descriptions pls find it.

[@zakaullah4359]

your notation is wrong cross mean in dot mean out

[@bhagyashribabar1923]

What abt 60 degree when ic=0

[@chandan7998]

Sir something hindi me boliye

[@learnwithus-electricalengi7390]

Sorry dear, I work abroad, and the motive of the channel is to reach out to students across the globe. Hope you understand.

[@jitenderverma1463]

Sir video Hindi bano ,,,
