Thanks so much for your videos! I am studying computer/electronic engineering. Currently busy with a project which relies heavily on heavy current knowledge and I must say your videos got me up to speed in no time! Continue the great work
Hi Varun, at 18:32 I'm not sure the Fouier coefficents stay at 3/2 as you go higher in harmonics? thank you in advance for taking a look. Anyway it doesn't affect anything in the concepts :)
Sir in the dc machines course vedio lecture 6 , u said that irrespective of machine being motor or generator in the armature we have always AC voltage Than why don't we supply directly AC voltage to armature of DC motor sir?? Instead of using commutator ?? Plz reply me sir
yes..see the idea is you need something to reveres the current when the conductor passes from one side to another which should happen when the conductor reaches that point when you use an ac supply with a set frequency it would not be possible to match these two based on your requirement of speed etc.....
Sir Tq ..........for ur reply.... When the conductor changes from one pole to other, direction of the current should change ( than only we can avoid torque reversal) It happens only when both frequency and speed of the machine are same Am i right sir????
Most of Our doubts are not getting clarified sir In the comment section If we post our doubts to recently uploaded vedio within 12 hrs there might be chances to get a reply but possibilities are less and for getting clarified And To the past vedioes which are uploaded one year back there is no possibility of getting reply to our doubts sir Plz find a solution to this problem sir Plzzzzzz sir we are requesting u sir
One thing u need to understand is that I am not a full time teacher in some college, so for courses which are taken two year back I myself need to refresh certain ideas. That is why I ask to put timestamps on the doubts so that it is easy for me to watch that part. If timestamps are not there It would be very difficult for me. But since you have told me let me see what can be done, Ill find something....

Best of luck!
hey what project were you talking about here?
Suscriber nhi hai sir lekin aap bhut achha padhate ho mind blowing,,padhana mat chodna sir
Do share the videos if you feel so....
THANKS RESPECTED VARUN SIR

Hi Varun, I take back last comment about 3/2 it is right at 18:25. However I think it goes +3/2 then -3/2 then +3/2.
Thank you sir
Respect Sir
sir is there a video on distribution factor?
Hi varun, at 11:26 minor correction m=no of slots per pole per phase

Am i right sir????
Sir, which book u followed??
❣️❣️❣️
Tq sir
Thanks ..
You're welcome!

In the comment section
If we post our doubts to recently uploaded vedio within 12 hrs there might be chances to get a reply but possibilities are less and for getting clarified
And
To the past vedioes which are uploaded one year back there is no possibility of getting reply to our doubts sir
Plz find a solution to this problem sir
Plzzzzzz sir we are requesting u sir

Tq..... Sir
I always put time stamps ....I know it's difficult to answer old videos ..But sir please try to reply ..humble request.
