THANK YOU
Stay Connected!! :)
बहुत शानदार तरीके से बताया आपने मज़ा आ गया सही मायने में teacher आप जैसे लोगों को ही होना चाहिए
Best explanation till date… I had serached quora, chatgpt and many youtube videos for this type of explanation. Thank you so much
10:30 Answer- the rotor can never reach the speed of rotating field, if it did then there Would be no relative speed b/w rotor and rotating field, hence no induced rotor current therefore there's no torque produced to drive rotor,,,then friction n windage will slow down the motor...
Bhai kya explain karte ho yaar acha kaasa revise hogaya.. 🤩
Aapki vedio bhut conceptually clear h plz banate raho vedio
Apki video dekh kr saare doubt clear ho jataa hai
Very good 💯 Sir ji..🌹🌹🌹
Mast video tha bhai. Go on with this flow. 💯
Sir aapka samjhane ka trika bhout aacha hai
Sir , Yeh Jo R2' (1/s - 1) hai , this represents the mechanical load of the drive concerned to which the induction motor under consideration , is coupled na .
Yes
Mast laga
Slip 0 ho gaya to koi relative motion nahi hoga, to koi eddy current develop nahi hoga to rotor rest pe rahega lekin yadi rotor rest pe ho gaya to relative motion bhi hoga....
Ok, due to slip one can say the initial current fetched by induction motor is more. But why it is 5 to 7 times the normal require current? Any derivation pl
Very nice explain and very informative video's keep it up.
The motor load, under normal operating conditions (and not a jammed rotor!) Will affect the time taken for the motor to accelerate to full speed and therefore the duration of the high starting current, but the magnitude of the starting current.
Is it correct ?? Please justify!!
Sir motor starting me slip s=1 he to resistance= 1-1/1 = 0/1 means infinity hota he naki zero.......
Very nice
Sir what are different between REF & Differential relay plz sir es pr ek video banaye ...bhaut jayada confused hota h
Sir,
Induction Motors ke upper ek video's banao please.
Thank you very much
Bahut achha
Sir there is one confusen if moto taking high current in starting then why we use star connection according your lecture in star connection Line current is less than delta connection. Reply me please
Aapke sawal main he jawab hai, kyun ki woh jada current leta hai isliye different different starter use ki Jaati Hai unmen Se Ek Hai "star-delta starter".
Jahn motor ko start krte waqt uske winding ko star main connect kr dete hai kyun ki agar Delta main rahata toh woh aur bhi jada current khiche ga and you know the reason why already explained in the previous video.
Sir your teaching is nice 🤩🤩
To sir is hisab motar pe kitne appear ka contractor aur over Losd rely kitne ka lgaye ?
Mast video bro ❤️👍
Pls make a video on equivalent circuit of motor and transformers and explain ...
Sir , 3 Phase Induction Motor mein Unbalanced loading kaise overheating create karta hai ?
Aur 3 Phase Induction Motor mein Overload aur Overcurrent ko bhi differentiate kardijiye .
Sir , Aapne Dekha Hi Nahin Abhi Tak Mera Yeh Comment ; Please acknowledge kardijiye Sir ki Aap iske upar bhi dedicated video banadenge .
sure, brother, I will make
Very good
Due to relative velocity will become to 0
Hence not rotate at slip is 0
Nyc teaching
Sir 10hp motor. 3phase per phase ma kitna current hona chahiya
Nice explanation
Thank you sir ❤
Very nice explain and informative video's keep it up
Please reply I was sending many doubt to you so please reply I like your video very much
Mast hay bahi
Thanks 🙏
Hmmmmmm......good
Thank you so much
Jabardast
sir ek single phase 3hp induction moter starting amps kitna legi
7*jada
6-8 times the full load current
Upload more video
Thank you
Bhai very 👍
Sir induction motor m back emf ka concept kyu ni implement krte
Sir Agar Rotor Synchronous Speed pe Ghumne Lagega To Phir Rotor Bars Stator ke RMF ke Flux ko Cut Nahin Karpayenge Jiske Wajah se Rotor mein EMF hi induce nahin hoga jiskeliye rotor bars end rings ke dwara short circuit ho kar circuit complete karneke bawabjood unmein koi current flow nahin karega jo ke lenz's law ke hisaab se producing cause RMF aur uske khud ke bichchhh mein jo relative speed hai , usko oppose karne keliye RMF ke direction mein ghumna chalu karega so that induction motor simply ghum hi nahin payega .
Induction Motor rewinding ke dauraan Agar Heating chamber mein galatise overheat hojaye , to kya hota hai . Main apna understanding post karna chahoonga which you please refine Sir zaroorat ke hisaab se .
Agar slip 0 hua matlab rotor aur rmf dono sath mein agya matlab ab rmf us rotor ke conductors ko kaat nhi payega.
Kya ye shi h
Yes
Nice
Sir star delta starter men motor starting current jyada lega ya kam
Jyada
Sir please tell that how induction motor rotor speed is less than synchronous speed
It isn't. But there's a slip, a difference between the angle the rotor is at and the angle the rotating field is at.
Super
Sir single phasing par bhi banao vido
3 me 1 phase cut hota hai use bolte hai
Nyc
Suru me star me keu chalate hai
Slip = Ns - Nr/Ns X 100 hota h
Bhai aajkal vedio nahi aa rahi
Sir aap knha se ho
Sir frequency kam hone par starting current kaise badhata hai plz help🙏
N= 120f/p
Torque saga formula details
Over all explain
Sir ap konsa job karte hain ?
सर 27/4.5 गोपाल आयल एक्सपेलर 9 बोल्ट को चलाने के लिए कितने एच पी की मोटर लेना चाहिए
मोटर उल्टी क्यों gumti hai
Do phase ko interchange karne par
Bahut bolte ho ! Jo Topic hai uspar baat karo na ..bhai . 😮
Aap samjhane main 100 percent fail hain is video main
Go, watch pogo
Very good.explaine.....
Very good
