Induction motor me torque ka formula kaise derive karte hai usi ko maine simple way me explain kiya h , #electricalpaathshala #inductionmotor #electricalmachine
Dekhiye jab rotating magnetic field rotor conductors ko cut karti h, to emf generate hota h or fir current banta h. ... Finally ye current jab Magnetic field se interact karta h to torque develope hota h, Jiski vajah se rotor rotate krne lagta h. (Ye sb kuch maine already starting ke kisi lecture me discuss kr liya tha). Now, Rotor Rotate kar raha h kuch Nr speed se ... And, Stator and rotor ke beech me Already Rotating Magnetic field present h jiski speed Ns h. To induction motor ke case me Ns hamesha Jyada hoga Nr se, It means ki rotor hamesha kosish karega ki vo Magnetic field ki speed ko catch kar sake ... Or jo Ye Nr and Ns me relative difference h dono ki speed me... Yhi Slip hota h. Basically Difference between Stator magnetic field speed and Rotor speed is called Slip. And in Per unit system we write it as (Ns-Nr)/Ns. Agar abhi bhi koi issue h to m aapko ek video banake explain kr dunga kuch time me.
Sir aap ka explanation wakai kabilatarif hai sir aap sa ek gujarish hai ki aap protective relay per video banay iske liye main aapka sada aabhari rahunga
Thank you so much sir 😊 But you didn't explain torque at synchronous speed. Actually I know torque at synchronous speed is zero because here is synchronous speed & torque developed is zero but given the extra explanation in the my book.
Sir, while finding the condition for maximum torque, we can find the condition of minima of the denominator by differentiation and then equating with zero?
Sir aapne te1/te2= E1/E2 likha phir usko e2o kyo kar diya because aapne to max torque is directly proportional to v1 ka square bola h na to jaruri h kya ki max torque standstill conditions me mile kyoki aapne s ko bhi one rakha h yeh samjh nahi aya
Starting torque and maximum torque ratio 80 percentage in an induction motor .if synchronous speed 1500 r. p.m when speed on maximum torque ? Plz solve sir
Sir from a reference book I found that T=K×{R2×s(E1)^2/(R2)^2+(sX2)^2} He use E1 instead of E2 . I read all his assumption and I found correct.pls reply
Dekhiye aap letter kya use karte h usse koi matlab nhi hota , uska meaning sahi hona chahiyeh ..m yaha E2 ko rotor induced emf at standstill bol raha hu , and E2s ko rotor induced emf at slip s , bol raha hu .... ab us book me shayd E1 ko rotor imduced emf at standstill bol diya hoga .. isliye vaha per esa likha hua h ... main baat jo samjhne wali h vo ye h ki .. induced emf of rotor at slip s = slip x rotor induced emf at standstill .... I hope ki aapko clear ho gaya hoga .. agar nhi clear hua to m aapko video ke through samjha dunga .. ek baar aap apne level pe samjhne ka try kijiye , nhi aaye to mujhe btayiye
@@Electricalpaathshala He assume E1 as applied phase voltage.... I am confirming in this two formula First of all he find T=K×(flux)×rotor current×rotor power factor
Ok, as you read in transformer that the induced emf of stator say E1, induced due to flux .. now this opppses the supply voltage (you can see phasor diagram) , as we all know the induced emf of rotor is also generated by the same flux (sayE2) .. so basically both induced emf are same at standstill condition after that slip comes into role .. so you can use any sign convention . I hope above explaination will help you .. try to relate three phase induction motor with transformer.
E1 or V1 is the voltage/emf supplied to the stator in this case. Also Tmax proportional V1 So more *supply voltage* more Torque developed in rotor (up to a limit only)
Yes , it is your choice , you can use whatever u want .. i have tau d to show it in a simple way that it is a developed torque .... but if you want to mention it with only tau .. then please write there that .. here tau is developed torque ..
K and k1 both are constant terms .. i put k1 in place of k and E2(square)... You can see in that step clearly that k1 comes in place for both ( k and E2 ( square) . I hope this will help you to understand
You know what i love you..you make me so comfortable with this electrical technology..😭😭😭.. thank you so much
Thanks sir perfect explain love you Electrical pathashala
You have done great work .. u completed asfak hussain completely
Yes I was reading that book that time.
Thank you 😊
The way of your teaching is excellent sir ... Barabar samaj hogaya sir......
Thank you sir , for making it simple.
Thanks sir, you have explained it very well
You are the best teacher sir best explanation sir..
Thank you very much sir
your way to teach is amezing sir
Thanks umang for watching our videos.
V good brother i understand this very well❤️
I love you sir for your teaching style ❤️❤️
Thanks sir...ache s smj aaya
Thanksss bhai kya smjhaya hai👍👍
Sir,
I love the way you teach us
Thank you so much sir
all concepts have been cleared
Tanks sir ashe hi powe system ke bhi video banaye plz sir i request you sir apke video dekhne she kabhi kuch shamj me aaa jata he.
Speechless explanation bhai ....👏👏👏👏👏👏👏💯💯💯💯💯
Bhi slip me thoda confused hu ki acutely hota kya hai.....
Please btao do..

Excellent
sir, turn ratio vala relation kaha se aaya .mujhe smjh nii aaya thoda vaha pr

Sir Rotor copper loss ka formula kaha se le Liya hai 3IsquareR2
can u please help me up with running torque of 3 phase induction motor ?
Nice work
15:48 negative term positive kese hua
Sir mai diploma ka students hu agar mere exam mai ye 10marks mai ya phir 20mai aa jai to kaise karu
sir torque at full load ya torque at no load kaise nikalenge??
Sir note milega em-2 ka imp..
Do tell what the E2, I2 mean, sir not everyone wants help in each topic from RUclips
Thanks sir
Good
thanks
Positive term negative kaise hua sir
Sir last video kaha see dekhe
At 20:55 Is E1 the rotor induced emf or Stator?
E1 or V1 is the voltage/emf supplied to the stator in this case.
Also Tmax proportional V1
So more *supply voltage* more Torque developed in rotor (up to a limit only)
pls explain individual terms present in equations
Plz watch previous videos also. I explained everything.
Sir iska equivalent ckt pura explain nahi kiye kyun
ruclips.net/video/7b1bbRMUL5k/видео.html is video me complete equivalent diagram h, isko dekh le aap
Sir iska full circuit diagram nahi dikhaye aur video khatam ho gaya
ruclips.net/video/7b1bbRMUL5k/видео.html
powers ka relation kaha se aaya ?
ruclips.net/video/juuRBfrDthc/видео.html
Jo link maine upar diya h .. uss video ko dekhiye vaha se power relation ka pata chalega
☺🙏
Why we use Tau d?
Can we use only Tau.........
Yes , it is your choice , you can use whatever u want .. i have tau d to show it in a simple way that it is a developed torque .... but if you want to mention it with only tau .. then please write there that .. here tau is developed torque ..
less theory
sir where is k in 12:52,,,,,you put k1 but skipped k why??
K and k1 both are constant terms .. i put k1 in place of k and E2(square)... You can see in that step clearly that k1 comes in place for both ( k and E2 ( square) .
I hope this will help you to understand
@@Electricalpaathshala thanku sir,,,,later i understood but then i forgot to delete my comment,,,sorry for inconvenience sir
No problem . Happy new year , may this year brings you lots of happiness.
