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.

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

@patakotisrinivas1918 5 лет назад

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

@derickmhlongo6399 5 лет назад

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

simple way of understanding concept. super sir

@pcpandey2059 5 лет назад

Mind blowing sir..very rarely explained concept..

@ramukorra157 6 лет назад

thanks sir,i really satisfies with your lecture

@s.manzoorbukhari3004 2 года назад

Plz keep uploading videos,your such a talented person

@learnwithus-electricalengi7390 2 года назад

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

@avenkatamahesh3296 5 лет назад

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.

@manisawhney1882 5 лет назад

Thank yu sir , at last I can visualize it

@jitenderverma1463 6 лет назад

@subhrajyotipal356 6 лет назад

Excellent sir need more videos on 3ph im

@naresh.damera 5 лет назад

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 5 лет назад

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.

@vyanketeshmishra3832 4 года назад

Superb explanation.....👍👍👍

@learnwithus-electricalengi7390 4 года назад

thank you dear

@apurvmj 4 года назад

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

@learnwithus-electricalengi7390 4 года назад

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

@prasadksr6459 6 лет назад

simply superb...

@shivasaiforyou-basicelectr1790 3 года назад

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.

@anujpatel2970 6 лет назад

Sir plz share competition question answer regarding railways or ssc jee

@madagalaharivardhan9412 5 лет назад

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 5 лет назад

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 5 лет назад

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

@jaypandya8629 6 лет назад

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 4 года назад

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

@learnwithus-electricalengi7390 4 года назад

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

@masoomahmed9348 5 лет назад

Jaanwar aaya. Jaanwar aaya.

@zakaullah4359 5 лет назад

your notation is wrong cross mean in dot mean out

@saurabhyadav2085 4 года назад

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

@learnwithus-electricalengi7390 4 года назад

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

@jaypandya8629 6 лет назад

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

@learnwithus-electricalengi7390 6 лет назад

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 6 лет назад

Thank you for your quick response

@jaypandya8629 6 лет назад

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 6 лет назад

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