Quality of content is really Great sir, Very great explaination.... Not any coaching institute matches your range of explaination in this short span of time sir.... I will surely buy full course as soon as i collect money into pocket....I'm confident that i won't regret buying Full course....
I'm watching all your lectures ... This is the first time I understood what armature reaction actually is!!! Thank you Shukla sir I myself am a teacher by the way and very much impressed with the way you teach..... Thank you very much once again for being so enthusiastic and curious And I love the way you use this camera ... perfect ...🙏🙏🙏🙏
Sir thank you 1st of all!! It is a request to you from all the EE students that please start Synchronus Machine after completing DC machine and keep Induction Machine aside and if time permits we will love to hear the lecture of Induction but we need synchronus badly.. Just consider it sir..
Sir please tell me armature occur in dc machine and synchronous machines both . In dc machine we don effort to eliminate the adverse effect of armature reaction .in synchronous machines we do not do anything for adverse effects of armature reaction.what is the reason behind this??
Sir please provide solution. A DC series motor has an armature resistance of 0.06 om and series field resistance of 0.08 om.The motor is connected to a 400v supply.The line current is 20 A when the speed of the machine is 110 rpm.When the line current is 50 A and the excitation is increased by 30%, speed of the machine in RPM is?
Sir 47:15 It means that the de-magnetizing effect occur only in motor Because the Armature flux shift only in motor In generator armature flux and the main field flux are at 90° to each other ..
Sir mera ek question hai...sir agar delayed commutation generator ka case me ho raha hai to motor ka case me forward commutation hoga mera mtlb generator me late se commutation ho raha hai to motor me pehle hoga??
A dc shunt motor on load current 30A armature resistance 0.6R. Supply voltage 240V. If 1R resistance is added in series in armature resistance. Torque ratio will be... UPPCL AE 1 JAN 2018
Greeting of the day sir...your lecture class is very nice and your class makes a clarity in this subject. Sir plzz upload single phase transformer. For this kind of act it will be very thankful for us.
Sir 17:43 D-axis for one pole pair is when..when the field line go through the north pole to south...but in case of 2 pole pair the d-axis is shown from north to North , south to south Why...?
Samarpreet Singh current sirf uss conductor main zero hoga jo brush axis main hoga. Baki sare conductors main current hoga,aur woh current brush se niklegi
@@umeshsingh-du3pk No. I asked my teacher and he explained me. At the instant of reversal current at the brush conductor should be zero otherwise sparking will be there(only at that instant). This was the point to be understood here . Suppose that positive polarity is there at brush A . At that time current will flow through it . When brush A is at negative polarity then also current will flow through it . But when the current is being reversed from positive to negative polarity, at that instant the current passing through the brush should be zero.🙂 I hope you get it ,otherwise ask again,i will explain again!
Samarpreet Singh current through the brush is zero. I didn't get that part. Since it is a DC generator, all conductors are connected to slip ring, and the conductor that is in the same axis as brush that'll have no current but all the other conductors that is connected to the slip ring will have current right. And the brush will collect the current from the slip ring only. Am I right?
@@umeshsingh-du3pk see ,when would the polarity be reversed ,when current goes from maximum positive value to maximum negative value . Right! So here also at the time of reversal current would first attain maximum value ,then become zero and after that attain maximum negative value. Hence reversal occurs when current is zero (average of ac). And at that instant of time current through the brush should be zero. This is because alternating current is generated in the armature winding.🙂

How much full time course fees
@@advait2018 check their website
I'm watching all your lectures ...

बहुत ही अच्छी तरीके से समझ में आ गया सर जी
I bow my head to the God of Electrical machine
.
One of the best lecture on armature reaction
Pankaj sir is best
You are the best teacher for machine
Sir thank you 1st of all!! It is a request to you from all the EE students that please start Synchronus Machine after completing DC machine and keep Induction Machine aside and if time permits we will love to hear the lecture of Induction but we need synchronus badly.. Just consider it sir..
Oh my god ! What an explanation sir..how can you exaplain in such a lucid manner..hats off to you sir
Best explanation i ever seen before... 🙏
One of the best lectures on armature reactiin for tge average student
great explaination sir...finally found someone who explain it very breifly
Respected sir
Your explanation is very good
Plz provide of full courses
Ajtaka koi bhi you tube par itna acha armature reaction nahi padhega great sir I salut you
Sir the explaination is very good... Every conception has been covered....
Nice explanation sir ji...phli bar koi ye concept clear kr paya h..ty
Sir synchronous machine upload kijiye ... Thank u sir ..
Best h revision ke liye mna and gna mai confusion ho rha tha ab all clear thank u sir
I didn't learn this in my 4 years sir... thanku so much genique
Esa quality content ab kaha dekhne ko milta hai
Solid, In detail explaination. Thank you.
Rare teachers teaches to satisfy. You are amazing sir
hats off !! im very lucky to get this knowledge for free
Thank you so much sir....excellent explanation
shikshanagari
Good explination sir
It is really helped me to understand the concepts.
Wah sir maja aa gyaa
Aise hi knowledge batate rahiye

Sir aap jaise koi nahi.
What a explanation sir!,thank u so much.😊😊😊
Wow..What a lecture... 👏🙏
My favourite electrical lecturer ❤️
best explanation...
go ahead sir
from Bangladesh
प्रशंसनीय,
अद्भुत
Badhiya
thnk you sir for such great explanation

Thanks for this lecture nice video

Very well explained sir ,Thank u sir
Sir 47:15
It means that the de-magnetizing effect occur only in motor
Because the Armature flux shift only in motor
In generator armature flux and the main field flux are at 90° to each other ..
Best explanation ever 👌
Sir mera ek question hai...sir agar delayed commutation generator ka case me ho raha hai to motor ka case me forward commutation hoga mera mtlb generator me late se commutation ho raha hai to motor me pehle hoga??

Very well sir
Quality content nice session
Sir 17:43
D-axis for one pole pair is when..when the field line go through the north pole to south...but in case of 2 pole pair the d-axis is shown from north to North , south to south
Why...?
Bcoz D axis is always a straight line. It is not necessary that d axis goes from N to S.
excellent sir. your student from pakistan
Aap se aacha koi nahi padha sakta.
!note 18:24 thita electrical
Respect🙌
All doubts r clear
Sir, the armature is vibrating, so what could be the problem when the motor does braking when the vibration does?
Best concept .
Sir genique par machine kab tak khatm ho jayega. Thank u very much sir ji
Awesome .....
Nice explanation sir
Full course kese purchase karna hai
Sir 2 pole k liye to sab samjh aa gya but sir 4 pole m d-axis and q-axis samjh nahi aaya. Sir please can you explain it again in 3D view.
Better than madsy
Awesome sir
Excellent lecture sir
Great lecture.
Sir mereko ek dout hai kie no of conductor used in compensating winding is less than the armature winding why it is pls explain any one
great sir
God of machine
Thanks sir
sir aap ssc je ae ka bhi lacture banao
Thanks
👍👍👍
thanks a lot sir
sir vo mortor k case me anticlockwise rotation current direction assume karne k baad rotation nahi mil raha hai
Smart lecture
Excellent
Nice to see you
Sirji apko pranam
40:35 par motor case me weakning nd leading wrong bol diya frequently but smjaa achee se rhee ho
Good sir
Sir this is crash course so hows a full course 😁
Isse bhi accha hoga
Nice
Thanksss sirrr
Most welcome
Sir how can I get paid course
Agar brush axis k conductor pr current zero hota h toh brush k through current bahar kaise jayega?😥

Samarpreet Singh yeah you're right, but brush is connected outside the commutation circuit right. So it's always collects DC current not AC I guess.
Thanks...

Sir which book is better for complete gate tutor

Suppab sir but likhe kese samaj nahi aa RHA hai
Correct hui thi na bat
.... 👍👍
Sir although I don't have any idea about armature reaction, shall I skip this video if it is not that important (gate point of view)?
boss video
bhai gadar phadaya
Jalde jayda karte ho
