Hello sir, I have two questions regarding interpoles. Now you said that the interpoles will induce a reverse emf inside the conductors undergoing commutation and result in the emf inside them to become 0 thereby reducing sparking. My first question is, the magnetic neutral plane will still be shifted and interpoles have no effect in returning it back to its original place. This means that there will be other conductors (under the new magnetic neutral plane) which will have a voltage of 0. Does this mean that the interpoles reduce the overall induced emf inside the generator? My second question is, this interpole will produce a magnetic field that should logically also interfere with the main magnetic field. Doesn't that increase the issue of magnetic neutral plane shifting? or is it that the magnetic field of the interpoles is negligible compared to the main magnetic field? Thanks in advance.
Hello sir. I have a small doubt. Wouldn't the interpoles create an emf when the MNP is in the position corresponding to no load. Wouldn't this create sparking at no load??
will the effective emf produced will reduce...???? since we use interpoles the emf induced in armature conductors in MNP old will be zero and at full load,due to shift in MNP the emf induced in the armature conductors at MNP new will also be zero and so the effective emf produced will also reduce....please clarify
i got a problem in understanding that the brush location always needed at the place where the current is have too be reversed for the build up of the voltage but what i see the brush it still in the old location of the neutral plan is it must be localized again of the new neutral plan and thanks
if the current in the short circuited coil fails to reverse, by the end of the short circuit it is called delayed commutation or under commutation....hope it clears your doubt
Sir plz solve the ques that came on gate 2009 re, relating to the shifting of the brushes along the direction of rotation and we have to find the voltage waveform on the brushes......plz plz plzzzzzzzzzzz solve this I am not getting a satisfactory solution anywhere
Interpole primary purpose is to reduce commutation , in doing so it will also reduce Armature reaction effect - Secondary effect of interpole. Like wise - Compensating winding - primary purpose to reduce Armature reaction, So if A.R. is countered Commutation already improved - Secondary effect.
Fleming’s right hand rule it is to find direction of EMF...here we already know what if the EMF we require...we have to find the polarity of the inter poles...
+naga raju yes that I what I am also doing here...I need an emf opposite to that of the one in conductors...and based on the a downward direction of flux would be required to generate that particular voltage with direction of velocity I have shown..and yes I tried with the right hand rule...ur middle finger should be facing you the thumbs from.right to left and then u will get a field from top to bottom..personally I use v cross B it's far more convenient rather than using twisting and turning ur fingers
when it was loaded MNP shifts and there is no short circuit at MNP(No load ) and then brushes shifts ,then if we cancel the emf by giving it in counter clockwise then emf will reduced ....so we are making emf zero ...what i understand is as emf was 0 at no load and non zero on load this will cause a sparking effect so in order to avoid that we are giving an counter emf right

i read my notes from class over and over again. it made no sense. thanks for your simple way of explaining.
Thank you so much...please also consider sharing these videos with your friends and anyone that might find them helpful..
Sir app ek dum clear ly samjha dete hai... very very thank you sir
Thank you Sir. For the first time in my academic life, I learnt something about interpoles. It was always a mystery till now
Aweosme, I hope things are crystal clear now... ;)

thank you so much..
Hopefully your channel will become very large one day ....love from bangladesh
Thank for the love...consider sharing the videos with your friends and anyone who might find them helpful...
You are amazing when its come to explain anything
Thank you
your lecture series is so much conceptual.plz keep uploading the upcoming topics.this series is so much helpful.thanq u
+omar faruque thank you very much...glad.to be of help..yeah now.onwards videos will.come.out consistent....
Keep working this channel is going to become very big in future...
Thanx
thanks you.. please do consider sharing the videos with your friends and anyone who might find them helpful...
Thankq so much sir this is the best
Sir, does reducing the effect of armature reaction can affects motoring action?
You're the best
Apparently Rahul was fired from his job of brush shifting 😂
good effort bro.keep it up
Thank you sir I got a good experience
Great

Sir your videos helped me alot... Please upload videos for induction machines ASAP
next will be transformer, because transformer is a precursor to understand induction motors
Thank you sir
Hello sir. I have a small doubt. Wouldn't the interpoles create an emf when the MNP is in the position corresponding to no load. Wouldn't this create sparking at no load??
Is this arrangement reducing the armature reaction or the commutation?
excellent lecture

I have one question, how are we gonna decide the strength of the interpoles, as the will vary. Please help me with this doubt.
Thanks.
i got a problem in understanding that the brush location always needed at the place where the current is have too be reversed for the build up of the voltage but what i see the brush it still in the old location of the neutral plan is it must be localized again of the new neutral plan and thanks

@@ElectricalisEasy aapne npcil interview qualify kiye hai. ??
@@ElectricalisEasy i have seen your blog.
I reached the interview round..but could not clear it..
@@ElectricalisEasy I have also given on 24 may 19. But not selected.
Sir can you come up with the topic compensating winding
It is already there in the channel
In books gen direction is CW and m/r is ACW
Sir where the interpoles are placed in a d.c machine
👌👌👌👌🙏🙏🙏👍
Sir, what is delayed commutation?
if the current in the short circuited coil fails to reverse, by the end of the short circuit it is called delayed commutation or under commutation....hope it clears your doubt
Thank you very much sir!

Let me check
@@ElectricalisEasy ok sir ...I am eagerly waiting
@@ElectricalisEasy sir if u are not getting the ques then plz provide ur mail id , I will sent u the picture of the question
Sir electronics per lecture start kariye pleas jb s mane apka channel dekha aur koi channel nhi dekhta
I would love to cover all the subjects, but there is also a time constraints with a full time job...
our lecturers said that this interpolating method uses to avoid armature reactions. but you tolds such a different thing. Explain me..
Whatever I have explained is from chapman book and h cotton book..and it is already explained with a fair bit of reasoning
@@ElectricalisEasy Am I right or wrong????
Interpole primary purpose is to reduce commutation ,
in doing so it will also reduce Armature reaction effect - Secondary effect of interpole.
Like wise -
Compensating winding - primary purpose to reduce Armature reaction,
So if A.R. is countered Commutation already improved - Secondary effect.
Sir, but by using Flemming right hand rule interpoles are getting opposite poles...can u see once..
Fleming’s right hand rule it is to find direction of EMF...here we already know what if the EMF we require...we have to find the polarity of the inter poles...
Sir,in Flemming right hand rule also if we know the emf the direction of field can be obtained ....
+naga raju yes that I what I am also doing here...I need an emf opposite to that of the one in conductors...and based on the a downward direction of flux would be required to generate that particular voltage with direction of velocity I have shown..and yes I tried with the right hand rule...ur middle finger should be facing you the thumbs from.right to left and then u will get a field from top to bottom..personally I use v cross B it's far more convenient rather than using twisting and turning ur fingers

thanks sir
Ye kon log hai bhai Jo itna dislike marre hai? Newton Einstein log hai kya ye log...jinko Simple Way me kuch samajh nai ata
motor case it will be different because to use left hand rule so to this method to applied motor case inter pole polarity will change
I would like you to change the name of the channel plz.
who said Electrical is easy, its not easy bro
