Excusme sir I have doubt...as per your explanation the brush position in zero volt ...how we get the output dc voltage from the generator..like 220 dc ,110 dc etc
That's left part with respect to commutator segment and the right part wrt commutator both bhaves as parallel not series so that it will become zero ! And off really the point in which the the commutator is placed it is in zero potiential then the starting and ending of the load resistor both are connected to zero potiential then no current should flow through the load !! Yes tha whole left part and right part among themselves becomes addetive , about sparking you said in first few minutes are right, but in that explanation which I mentioned above , something is ambiguous!! And one fact at mna or cloils closer to mna induced emfs are higher or maximum casue flux linkage is zero or less but rate of change of flux is maximum , and vice versa under the poles !
Brushes are physically placed at d axis that's true but conductors shorted by those brushes are placed at MNA so basically it performing the same job even it is placed at d axis instead of MNA
No..... Brushes are placed along MNA so that while connecting stationary brushes with movable commutator....there will be no sparking. For more clarity... Watch my dc machine series
The students who have you as a Teacher are lucky...Thanks for such an amazing and interesting explanation
Bhai esse teacher to bde bde coaching aur academy me nhi hai...such me best for explain..... 🙏🙏
Bhut jabardast sir lecture h aise hi upload krte rhiye khuch logo ko share bhi kiya hu.
Bs 5+3 = 7 nhi h😊
Very well explained ✨ without complicating things
Very fantastic lecture 👍 sir
I don't get the signs at 12:37

Very nice 👌
Keep it up!!!
And thank you!!!
Sir what is anterpolar axis in dc machine
Interpolar means between the poles.......
Pole have d axis and in between their exist q axis.
So Interpolar means q axis.
Hello sir. Is wale video mein sir calculations kaise hui hai??? I1 and I2 ki samajh ni aai
There is a calculation error....... Instead of 5+3=8 I write 7........but the concept is okk......i hope now u can understand the calculations
Yes Sir thank you
Thank you sir❤
Watching 3rd times 👌🏻👌🏻
What language is this? I kindof can almost make out some english words.
Hindi.... With some English words
Love you sir ❤❤❤❤❤❤❤
very thank u sir.
Thank you sir
It is true that brushes are placed along MNA
But sir physically or practically *brushes are placed along d-axis*
Yes.... Practically the brushes are placed along d-axis. I will make a separate video on practically placement of brushes.
@@techinsight1418 Is because the inter-pole maintain the 0 volt at the centre?
Sir, am I right?
No,... This is because of commutator. Check this video;

Thanks sir
U started very good in English in the last lecture 😡😡😡😠
5+3=7😂
👍🙏😊
Brushes should be place along with D axis not along MNA
No..... Brushes are placed along MNA so that while connecting stationary brushes with movable commutator....there will be no sparking.
For more clarity... Watch my dc machine series
@@techinsight1418 done. We can place them at both i.e. d axis and mna
For no sparking.... Brushes are placed along MNA and never be on d axis
"Practically" the brushes are placed along D-AXIS..... To clear the doubt i will surely make a video on this topic in full detail.
@@techinsight1418 HELLO SIR did you make the video of practical placement brushes on d axis?
