Induction Motor #20 - Speed of rotating magnetic field's wrt to Stator #1

[@patakotisrinivas1918]

Excellent explanation sir..thanks a lot for explaining it so easy...

[@brianburgess5160]

Hello Varun, thank you for another wonderful video. I had been incorrectly visualizing the rotor produced magnetic field as rotating at a different angular rate from the stator’s magnetic field. That concept continued to force doubts and this simple explanation and visualization provided one of those rare moments where it suddenly all made sense ;). Cheers!

[@beaconing7689]

I don't understand why this subject is so hard to find in google, i can't find straight forward answers; luckily i watched this video. Thank you sir 🙏

[@livewireyoutube]

Thank you for taking up a topic that is rarely discussed.

[@larrydurante6670]

Brilliant, well thought out explanation ! thank you

[@dheeraj3053]

Very good sir 👍🏻

[@ankeshwasnik7263]

just one word for u : awesome

[@simransingh2060]

Great way of teaching

[@ElectricalisEasy]

Glad you think so!

[@baalakrushna8761]

I am Preparing for PSU, I got u channel link by telegram and go through that videos i.e Induction Machine videos where really useful for exam point of view Tq Sir. I want to know where u r also planning for Power system too videos also

[@ElectricalisEasy]

No plan for power systems

[@TheGreenAlchemistSojib]

Sir which book you are used for numerical??

[@mtvpayyanur]

Here the topic is Excitation given to stator and rotor windings are short circuited. But if rotor windings are short circuited how a rotating magnetic filed will produce in rotor ? You said, for producing a rotating magnetic field we need a 3p supply and a 3p winding(ie 120 deg apart) right? So if rotor windings are short circuited, how rotating magnetic field will produce? Please clear my doubt Varun

[@ElectricalisEasy]

Unless the winding are closed or shorted how can the current flow in the rotor? That should answer the doubt.

[@mtvpayyanur]

@@ElectricalisEasy ok, got it

[@Professor_el]

What happens when nm is increased , how is the stator current affected ,please explain

[@piyushkumar8182]

Sir,rotor windings are 3 phase, as they are arranged in the structure 120 deg apart, but how the induced currents are also 3 phase?

[@prasanthvijaykumar7819]

Great lecture sir

[@ElectricalisEasy]

Thank you...do consider sharing the videos with your friends and anyone who might find them helpful...

[@mtvpayyanur]

How the rotor current is produced?

[@civilschandragiri1395]

Sir please provide video on....armature winding on rotor topic in synchronous machine

[@az-op8oc]

Sir your pdf handwritten notes ended with lect 19 from 20 lecture please share your notes,if it is possible.please share this as much as possible

[@suryaprakashmishra1599]

respected sir can we say air gap field same as rotating magnetic field

[@ElectricalisEasy]

Yes the field that is usually produced by the supply frequency is termed as the air gap flux...

[@suryaprakashmishra1599]

@@ElectricalisEasy thank you sir and one thing sir can i send my doubts to your mail id although i attended my self but want to clear from you

[@ElectricalisEasy]

Yes u can send at [e-mail]

[@abigt282]

Sir,but how would we know that stator rmf and rotor rmf rotating in the same direction....

[@mtvpayyanur]

Speed of the rotating magnetic field produced by the rotor, Nr=sNs, ok. This speed, Nr is with respect to what?

[@andrewvictor1489]

Nr is the speed of magnetic field with respect to rotor conductor , as Nr=Ns-Nm=SNs

[@ruchikathakur7941]

where is speed control lecture in this videos.

[@ElectricalisEasy]

Starts at Lecture number 45

[@ruchikathakur7941]

@@ElectricalisEasy I could see till lecture 44only

[@ElectricalisEasy]

Not sure why you could not see it...here is a seperate playlist : Speed control of Induction motor: kzbin.info/aero/PLPpCFgQP7QKGkxJS0Kt7dbwoHofbL7ao3

[@cinetalks299]

Plz provide same concept video on synchronous machine plzzzzzzzz sir..

[@ElectricalisEasy]

There is a full course on synchronous machines in the playlist section.

[@cinetalks299]

But this concept is not there in the play list

[@civilschandragiri1395]

Sir please provide same concept on synchronous machine

[@brincebabu8412]

Nm=SNs Therfore can we write rotor rotating magnetic field wrt rotot conductors=Ns-Nm=Ns(1-S)

[@daviduday1790]

wrong!!!!!!! because Nm is not equal to SNs. Nr=SNs , so speed of rotor rotating magnetic field wrt rotor conductors is Ns-Nm=Nr. And we are the one that defined that Rmf is rotating at Nr wrt rotor
