I think these classes are more than enough for the people those are preparing for SSC JE exam Not even a single bit getting out of these lectures Thank you sir...
Hello sir I have one doubt At normal condition Emf induced at the conductor placed at MNA axis is zero so there is no current through that conductors. Whe we are discussing armature mmf, at MNA axis maximum mmf is produced, why? If no current through conductor, how mmf will produced? Please clear my doubt
Sir bushes are placed at gna and whichever conductor wiil be at gna will produce zero emf as angle b/w flux and velocity is zero or 180. So How the emf is transferred to the load through brushes as the potential at brushes is zero?
@@lecturesinelectricaleng 🙏🙏🙏Sir Plz clear my doubt and give answer. 1. The shape of main field flux 2. The shape of armature MMF 3. The shape of armature flux 4. The shape of induced emf in armature conductor 5. Flat topped & Trapezoidal both are same.
Sir earlier you said that by increasing the number of conductors in the slot we will get a stepped wave form. But here it's a ramp type waveform for armature flux. Sir why is it so?
Sir can you pls once draw the diagram of shifting of MNA in case of motor Bcz in case of motor we give supply to armature and then find the direction of rotation And then the same current of armature current is used to study it's effect on maine field Infound that it is same in case of motor too MNA shifts in direction of rotation

Thank you sir...
All the lectures are awesome...
thanks, sir
I'm a big fan of you.
What an explanation, covered even minute concepts as well....thank u sir
Very effective explanation sir.Thank you so much sir.
And I am happy that entire machines subject u r uploading...thanks a lot
Thank you for the easiest explanation ever... 😊❤
Thanks Sir. Really timeless content.
Sir , at 10:12 why only South Pole is considered for armature flux ?
Tq very much sir ur giving us to the wonderful lectures I am big fan of u sir
Very good lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Sir practically we place the brushes at the commutator segment which is outermost part of armature but why here brushes are considered in the armature
Neatly explained sir...
Hello sir
I have one doubt
At normal condition
Emf induced at the conductor placed at MNA axis is zero so there is no current through that conductors.
Whe we are discussing armature mmf, at MNA axis maximum mmf is produced, why?
If no current through conductor, how mmf will produced?
Please clear my doubt
@@lecturesinelectricaleng thank you sir 😊😊😊👍👍
Thanks sir understood very well

Sir, For motor MNA shifts in which direction ?
The shape of induced emf in armature conductor of a dc machine is ?

2. The shape of armature MMF

Good explanation sir

Ok sir
Sir, What is the shape of main field MMF ?
Is M.N.A shifted at counter clockwise from G.N.A In Motor ?
Sir
Thank you sir love you sir
@@lecturesinelectricaleng sir could you please tell me the important software related electrical Engineering
Sir, how do we know that saturation in DC generator takes place at TPT
thank you sir
Sir pls explain how maximum value of flux density is increased
Thank you sir.
Thank you sir...

Sir can you pls once draw the diagram of shifting of MNA in case of motor
Bcz in case of motor we give supply to armature and then find the direction of rotation
And then the same current of armature current is used to study it's effect on maine field
Infound that it is same in case of motor too MNA shifts in direction of rotation
