- Pole Pitch, Coil Span, Back Pitch, Front Pitch, Commutator Pitch in Armature Winding of DC Machines are explained in this video.
Lap and Wave winding are explained.
Full Pitch and Short Pitch Winding are explained.
Progressive and Retrogressive winding, Open and Closed winding, Simplex and Multiplex winding (Duplex, Triplex etc.), Single layer and two layer winding etc. terminologies of winding are also explained.
At 7:39 there is a mistake. I am writing pole pitch =Z/pole =Z/slot .
That is a mistake. Z/slots is wrong. It would be slots/p.
I have mistakenly interchanged slots with poles in the last equation.
Correction is explained as below:
Z = no. of conductors = no. of slots in single layer winding, because each slot carries only 1 conductor.
No. of poles = P
No. of pole pairs = P/2 = p
Pole pitch = Z/p = Slots/p

I searched many videos on TH-cam platform but didn't understand this pitch related topic. After that I got this video and now i really understand the topic .. thank u sir
You are the best. There's no way I would have visualized it this way. Thank you.
Thank you so much.
Finally some useful information about windings that I can visualize. A hundred thanks to Jimit Shukla.
Thank you so much. I have been searching through all over the internet and ended up in your lecture. You have explained so well. Thank you so much.
Truly practical approach to understand the theory of windings of armature and commutator ❤.
it helped a lot to understand the terminologies , thanks a lot
I think, now I got the correct and easy to understand concept about the lap and wave winding concept related to the pitches it's the topic is very confusing but after seeing this vedio I have no any confusions about lap and wave windings but still iam going to see this vedio one or more times to clear about this concept but anyway you are doing lot of efforts to understand this concept Thanks a lot
And thankyou so much sir.❤❤❤😂😂😂
Very good explanation I need to watch a few times, but much better explanation than other videos 👍
Nobody has explained it better than you 💛
Thank you 😊
Nice explain sir 🙏🙏🙏🙏🙏🙏🔥🔥🔥🔥🔥⚡⚡🔥🙏🙏🙏🙏
the best explaination
Just awesome sir🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻 I'm so thankful to u for making this splendid vdo...pls do make vdo for all chapter of Machines and all topics of dc machine, pls sir 🙏🏻🙏🏻🙏🏻🙏🏻u make us understand in very easy way❤️❤️❤️ I was very scared of Electrical machine sub ...n I watched many vdos on this ..but finally found ur vdo as a saviour. You made this sub so easy... it's my kind req to u sir pls make vdo for all topic of dc machine and other chapter as well ...pls sir🙏🏻🙏🏻🙏🏻🙏🏻😭😭😭
Thanks for your appreciation. Its a motivating force for me. Keep watching the channel for videos of DC machines and other topics of electrical machines. There are some videos of basics of DC generator, and more coming soon.
I am happy that it helps you. But keep that in mind, it is the student (yourself) who has the ability to understand, and so not just the teacher is to be given the credit. Don't be scared. You will understand all that is to be learned. All the best.
@@jimitkshukla sure sir, thank you. Sir can u explain me what's parallel path while deriving emf EQ... I'm getting confused between no of parallel path and no of conductor...r both same? Or, parallel path is slot?
@@jimitkshukla sir are you in Telegram? So that if I stuck anywhere I can ask doubt there if u don't mind then...
Yes.
The way of explaining is exceptional, the model, concepts were amazing. No one explains as such. The video i was always searching 🙏🙏
Thanks for ur explanation. I got best idea from ur video.
You are welcome. Thanks for your appreciation!
Crazy explanation pls just keep uploading video we guys are with u❤️🐱
So many thanks sir, explaned a complex topic in very very simple way.
It's great idea actually 🤩
Very good. Thanks 🙏🙏🙏🙏🙏
Best explanation ...Pehli baar back pitch and front pitch ka funda clear hua he thank u....Sir agr possible ho toh special machine par lecture di jiye
Thank you very much.
thank you..for your clear explanation ..thank you so much
Wonderful explanations 🙏⚡
Thank you 😊
The best explaination!
Thank you so much.
Thank you so much sir
Better than a book
Very excellent explanation. Thanks so much and God's blessings! I have some more questions about DC machines, how do I reach you please?
Thank you sir🌄🙏
Best one..
Thank you
Nice explanation
Thanks ❤🙏
Awesome. Even my College Teacher failed to explain like this. Kudos!!!
What is the use of double layer winding and single layer winding??
That helped a lot. Thanks
Glad it helped.
Thanku sir.You explained it very well
You are welcome. I am happy you appreciate it.
The method of explanation is exceptional, and the model and concepts presented are truly amazing. No one explains in such a thorough manner. This video is exactly what I've been searching for. ❤❤
👍👍👍👍👍👍👍👍👍👍👍👍100% concept
Sir at time 10:17, ek coil jb full pitched h to uske dono conductor me induced emf out of phase hone chahiye na Qki ek conductor N-pole side h and dusra conductor S-pole side h. Sir please explain ❤❤
What's the cause for excessive sparks on the commutator bars?
Thank you very much sir
You are welcome 🙂

Pole pitch= Z/slots , here(7:41) both are equal so pole pitch should be 1 . But you are writing it 8. How?
If we have n conductors , we can create a single coil of many (n/2) turns or n/2 coils of single turn . Am I correct????
Beessst explanation...... 🗣️
Glad you liked it
Sir
Can you explain what are the advantages about each winding systems pls
new subsripber after watching only 2 min video
well explained
thanku so much sir
crystal clear explanation. Thank you so much for making this video.
Realizing it that pitch means the distance between two entities of an armature.
Super Jimit
Please send any pdf Armature winding
Amazing way of explanation by model
Why average pitch is taken as pole pitch in lap winding?
Thank you Professor!
Thank you dear 😇. "Professor" 😎
excellent presentation ...Thank you sir
☺☺😃
Best explanation method
Thanks a lot
Aap back pitch ko 4 (@16:52) bata rahe hai aur sath hi ye bhi bol rahe hai ki back pitch hamesha odd number hota hai. How????
English kiyu boltiho hindi bolneme sharam atihe keya. Hindime samjao na
Sir good explanation 👍.
7:39 pole pitch =Z/pole =Z/slot . Could you pls explain.
That is a mistake. Z/slots is wrong. It would be slots/p.
I have mistakenly interchanged slots with poles in the last equation.
Correction is as below:
Z = no. of conductors = no. of slots in single layer winding.
No. of poles = P
No. of pole pairs = P/2 = p
Pole pitch = Z/p = Slots/p
Thanks for your question, as it identified the mistake. I would add this correction in video description so that future viewers/students are not confused.
aapne bade bade grapics walo ko bhut peeche chod diya sir,...hatsoff to you and your technique of explanation
It was helpful. thank u
Bro very well done.... i have seached it on internet every video but doesn't found this type of practical information. Thank you

Very helpful with the practical demonstration as well as the pictures popping up. Keep it up sir.
Very informative video.
Thanks 😊
What an effort! Great explanation, sir. Lot's of love😍
Hands up
For explaining back pitch you placed the coil sides in such a way that back pitch is 4. And then told that it will be an odd number. Please give clarification. Also please clarify, for pole pitch calculation, if fore example north pole comes at slot 1 and south at 8, pole pitch is 7 or 8.
The placement is to demonstrate and for better understanding of concepts.
I did not realize (as my focus was on explaining) that I placed it in such a way that back pitch happened to be 4, an even number, which is contradicting the concept which I was explaining.
Please pardon me as it created confusion in understanding.
I appreciate your observation. Your comment made me realize that I must also keep these small details in mind while demonstrating concepts. I will take care in future.
Pole pitch calculation:
North pole at slot 1, and next south pole at slot 8, then pole pitch is 8 - 1 = 7. (Understand by example: distance between 1 cm mark and 8 cm mark on a scale (ruler) would be 8 - 1 = 7 cm).
This pole pitch is in terms of number of slots.
Other methods:
Pole pitch (in terms of slots) = total no. of slots / no. of poles
Pole pitch(in mechanical degrees) = angular distance between 2 adjacent poles = 360/P or 2𝛑/P
Pole pitch (in meter or inch) can also be calculated as arc length between 2 adjacent poles on stator inner circle with diameter D
So Pole pitch (in meter or inch) = circumference / no. of poles = 𝛑D/P
Nice nd proper explaination with that model..
Best video ever. Everything is crystal clear. Thanks a lot!
Everything is as clear as water. Thanks a lot sir ❤
Best explanation ever, Gratitude
Wow awesome 🎉😊thank you 🙏🏻
Bro! You Nailed it.
Thank you!
Hatsoff to ur teaching sir 😢
