Armature mmf shape | Space Harmonics vs Time Harmonics | (Subtitles included) PiSquare Academy

[@fivosteren1382]

He is dealing with very interesting and least explained issues. Congratulations

[@I_love_doracake]

yes.. 100 percent i liked your video sir... i am working as a lecturer in an engineering college... i played your videos in my class... students listened that very interestingly.. so i request you to explain about eee concepts with more practical session than theory section.. thank you

[@ThePiSquareAcademy]

Thank you Mr. Selvi, Keep watching and keep sharing the videos with your students, much more videos are coming up next, subscription to our channel will help them to stay updated with our new uploads kzbin.info.

[@abinessg6895]

sir your way of teaching so good and i like it very much ..it would be nice if you make a playlist of dc machine covering entire syllabus bocz none of the videos for dc machines is good ..plzz sir help us out

[@solarize.your.site85]

Thanks sir for clearing this concept.

[@Praveen1991917]

Most underrated video regarding time and space harmonics.thank you sir

[@mohadinthu]

Sir pls answer my question u explained that MMF waveform is stepped wave form then how and why are u considering armature MMF as perfect triangular wave form in armature reaction..thanks in advance

[@jeniferroselin5198]

Thank u for your videos sir, plz upload dc machine characteristics

[@rishigautam9295]

How armature mmf is triangular, you asked in armature reaction lecture to visit this video. Clarify this..you have taken my time..

[@parmarbhuvnesh1416]

please tell us more about time harmonics in 3 phase and various losses on machines and transformer due to time and space harmonics.And please do it by animation, as it gives a better understanding. Thank u

[@flowerpots7289]

Sir, I have a doubt regarding the shape of mmf with dc current in one coil alone is given as square wave in this lecture vs shape of mmf with dc in one coil in lecture " time axis vs space axis" being given as sinusoidal..and mmf zero crossing instant with respect to conductor placement is shifted by 90 degree with space where as in this lecture it is given as zero crossing in mmf wave exactly at where the conductor is placed.plz explain

[@enweluhananayah9059]

Greetings and happy New year. I listened to your discussion on space harmonics and was very impressed. How do we avoid it? Does the waveform look the same like back-emf waveform or it appears in bar chart? Thank you

[@narayanamjairamdesik9007]

Awesome explanation

[@Iamchiru123]

Please discuss physical significance of reactive power

[@haribabu9671]

Sir do video on why motor starters using star to delta why not delta to star Why small rating motors mostly use star connection

[@ajinkyadagadkhair5474]

Hello Sir, Can you please explain that the waveform of mmf for a single coil armature has positive constant value in between the slots though the flux direction is downward in it and same for the other part of the waveform

[@ElectricalEngineeringTelugu]

Why the frequency is standardized at 50hz and 60hz why not at other frequencies ? Please explain it sir.

[@amarnathmishra1461]

Good presentation of a difficult subject

[@ThePiSquareAcademy]

Glad you liked it

[@Sanjivanii]

Thanks sir, I kindly requested to you,please make video on actuall dc and ac winding connection and how different factor affecting them.

[@ThePiSquareAcademy]

we already have a videos on that please go through our channel kzbin.info/www/bejne/porEZomFlrZ7r9E kzbin.info/www/bejne/e4vNoYGlpLiLf9E

[@puneetshrivastava4676]

Fantastic

[@krishnateluganti3312]

Kindly make a video on HT operation and maintenance

[@debashisjana5570]

Is it true that armature mmf will b stationary w.r.t. stator magnetic field for dc m/c? or there should some cases exist?

[@Praveen1991917]

Sir please try to tell the difference between electrostatic field and electromagnetic field.

[@sonalgarg6632]

Sir please upload lectures for synchronous machine also. Basically armature reaction in synchronous machines.

Wonderful video sir. Keep your good work going.

[@sivanarayanabojja3089]

Can you please provide concept of relay coordination

[@rittikbiswas]

Sir we know dc machine armature current always flow AC , so how you feeding constant current (DC) in armature ? 2:20

[@parmarbhuvnesh1416]

One more request ,can u do live session on you tube rather than facebook .

[@laxmipadhi6068]

Hi Sir, Pls make animation videos on location of brushes & how brush gets short circuted with commutator segments.

[@rahulsr7918]

slip power recovery scheme in induction motor, introduce it plzz

[@ThePiSquareAcademy]

sure dear rahul

[@kannanr9016]

Volume quality is very poor sir please improve that ....

[@patakotisrinivas1918]

good explaination but still we want more information

[@ThePiSquareAcademy]

Sure Dear Srinivas, as we are tying for entry level things in electrical engineering we could just give you the glimpses of basic to avoid the misconceptions. In future we will dive in to the details.

[@kurapatianwesh9114]

sir i think the height will be 2Ni

[@ThePiSquareAcademy]

Dear Anwesh, if two conductors are there per each slot then it will be 2Ni, as there is only one conductor/slot, it will be just Ni.

[@Adityasingh-sq7gd]

Sir upload video

[@jeganmuthu6962]

Sir, Please upload videos in English,u don't know Hindi ,so please re-upload lift two button and Electrical statistics in English.

[@ThePiSquareAcademy]

Yeah sure we will re-upload the same, don't worry

[@wabstreetart8764]

Ffm

[@kurapatianwesh9114]

ni-(-ni)=2ni

[@ThePiSquareAcademy]

It is not ni-(-ni), total peak to peak itself is NI, as ampere turns means, product of no of turns(N) and the current flowing through the conductor (I). so one turn contribute NI mmf, with NI/2 in positive direction and other half in negative direction.

[@manojkumarsinha1239]

Your way of teaching is too boring. And you take too many pauses. God bless you.

[@ThePiSquareAcademy]

Thank you for your feedback.

[@ganeshd480]

very nice sir
