Bde bde academy ke teacher bhi itne achhe se nhi samjha pate hai jaisa aapne smjhaya
Thank you very much 🙏

[@fitnessadda5815]

Tnx sir aaisa kisi RUclips teacher vale nhi padaya jaisa ki AAP samjaye

[@electricalmaster5716]

Super teaching i very well understood from you sir

[@akashsarkarofficial1183]

Thanks❤❤.. Bahut achha se clear hua☺️

[@sanwariya02]

Thanks a lot😊...I was confused in this topic but now I completely understand this topic thanks once again...

[@mrx_3268]

Mana subha sa 'armature reaction' ko la kar batha tha par mujha thik sa samaj ma nahe aarahatha,par app ka 23.21 min ka explane maa mujha sab kuch samajma ahgea.thanks sir.

[@biswajitlaskar6071]

Thank you bhaia. Mere eha pe eisi tara explanation koi nehi kar sakta. Apne bacha lia bhaia. Exam tha mera. Apna video dekhke ekdam samaj gaya. Love you bhaia. ❤️ Best wishes and keep it up bhaia. Thank you 🖤 for your work.

[@electricalacademy2783]

Thank you very much....

[@gmallrounderbhai1.m275]

Thank you sir ji osm explanation

[@c_70_mohammadajmalturk46]

Nice explanation

[@kamalakantachhanda9681]

Bahar badhiaa sir

[@cutecrafts4557]

Sir ur hand movements super...I am able to understand easily..

[@sayanparui2617]

But sir in DC machine the carbon brushes are not shifted . They are all fixed but their is no sparking . This is my confution

[@keepsmiling4837]

Great sir, i understand properly. Thank you very much.

[@electricalacademy2783]

You are most Welcome

[@apoorva158]

I like your explanation.

[@biswajitkundu8278]

Very goodly explanation thank you sir . God bless you .

[@electricalacademy2783]

Ur Most Welcome sir.

[@ziaurrahaman138]

I understand very well, Thank you Sir

[@sharathnair1702]

Best possible explanation. Thanks man

[@ishaqahmed6247]

Thax sir it's very helpful

[@patelchirag9530]

Thank you so much ..its very detailed and understanding..keep it up sir

Excellent explanation.....

[@kavyak809]

Very helpful

[@surajphunde1111]

Very very good video sir,thank you sir

[@electricalacademy2783]

Welcome sir

[@sushantkhetle5919]

Very Nice video sir ❤️

[@rajaramyadav7546]

👍👍👍

[@markdavid5254]

Very helpful... Thanks

[@electricalacademy2783]

Thank you Sir😊

[@sanwariya02]

But I have one doubt brushes always placed they not rotate why they change with M.N.A.

[@nitikeshyewale3006]

👌

[@gmallrounderbhai1.m275]

can you
Explain Purely Resistance Circuit in brief.
Very Soon

[@mohdfaizan5317]

Brushes are placed on gna not mna clarify

[@koushikkar1601]

Thank you sir

[@Nandita_APO_Nabagram]

sir how crossmagnetizing and demagnetizing effect neutralised?

[@RAHULTIWARI-gc8hx]

By using Compensating winding ,Interpole and High Reluctance tips .

[@vijaykumarpasupula8676]

👏🏼👏🏼

[@tusharkantidebnath2316]

You are awesome sir..

[@electricalacademy2783]

Sir cross magnetisation and demgnetisation effect ye armature reaction ki vajha sae hi hota h na ??

[@electricalacademy2783]

Yes

lv u sir

[@pankajsanwal2010]

आपका way of explanation अच्छा था । लेकिन यह बात क्लियर नहीं हुई कि जब MNA variable है तो carbon brush को set करने की exact position क्या होनी चाहिए ?

[@electricalacademy2783]

Now there is no need of shifting position of carbon brushes because interpoles and compensating winding can eliminate the effect of armature reaction effectively. So there is no need of shifting of brushes.
Comepensating winding is placed on field poles and wound in opposite direction to the field current. And interpoles are created to in opposite direction to the armature flux so that overall effect of armature reaction can be nullified.
Thank you for asking.
Stay tuned with us

[@pankajsanwal2010]

धन्यवाद , मैं भी लगभग यही बात सोच रहा था । क्योंकि जब हम practically किसी D.C मोटर को देखते हैं तो एक सेट तो कार्बन ब्रश का GNA पर ही होता है । thanks a lot for quick response and read my comment carefully.

[@pankajsanwal2010]

Sir जिन मोटर्स में जिनमें इंटरपोल और compensating winding नहीं होती है , उनमें armature reacton कैसे menage होता है ?

[@electricalacademy2783]

Small size i.e. for small rating motors ,the effect of armature reaction is very very less under normal conditions as the armature current is very less so that we can simply neglect it. But for the Large Size i.e., large rating motors we cannot neglect the effect of this reaction, in that case compensating winding or interpoles must be there to minimize the effect of armature reaction. In some cases both compensating winding and interpoles and in some cases only compensating winding or only interpoles used. This all designing factors will depend on type, rating or size, cost and life of the Machine, effect of sparking.
So according to requirements all the provisions will be decided.

Your Hand desturbunce create kar raha he

[@electricalacademy2783]

Now issue resolved for further videos

[@PawanKumar-ks5su]

Motor me armature reaction nahi hota armature reaction sirf generator me hota hai

[@electricalacademy2783]

No dear.armature reaction is taking place in both motor as well as Generator
