sable alag explanation bhai, or sabse logical but ye bataiye mera doubt ye haiki, hum jab rortor me resistance lagate hai to, rotor me current ko aane se rokte hai, matlab current kum aa raha hai, par torqe ko drive karne k liye current chahiye n???, agar toque badh raha hai matlab load badh raha hai, or agar load badhega tab current apne aap badhega. pr hum resistance laga k current ko rok de rahe hain. or baki jitne youtubers ka video dekh raha hon, wo log keh rahe hai, resistance jyada hone se current kum hoga jisse torque badhega jispe mujhe thoda v vishwas nhi ho raha
Bro, Actually adding external resistance to increase the torque in the starting condition only not always. So, when motor will run as it's full speed the external resistance will be terminated.😊

Thanks sir for clearing my doubt. From many days I was having this doubt and no one was able clear my doubt in a easy way but you made it so easy to understand that I will never forget it 🙂
How much power factor increases, that means higher limit. Also only p.f. is sufficient to increase the torque or any other parameter variations required. Thank you very much
You are right. When we add external resistance rotor current will decrease and power factor will increase till some value of resistance i.e., r2=x2. Untill r2=x2 the decrement of cirrent is less than increase in power factor so total power will increase. But when r2 is increased more than x2 the total power will decrease.

nice explanation cos0==1 multiplying factor!. voltage current in phase or current following closely with voltage will absorb energy faster hence produce more torque, also lesser heating due to copper losses in winding.Heat always weakens magnetic field!. Divert heat to resistance than copper winding!.
Yesterday i was discuss this topic with my frnd... But i don’t understand whole concept and today i found your video... Thanks brother my all doubt are clear now regarding this... 🥸👍
Agar hum log external resistance ki nikal de aur uss jaga pe ek drive install karke let ek Crane ki chalaye toh starting torque kaise improve hoga can u explain.
Hi sir, very nice explanation. I have 1 doubt , Tst ke formula me sX2 ka term to neglect ho jata h aur denominator m sirf R2 rhta h, to R2 to inversely proportional kyu nhi hua torque ko?
galactic cosmic rays attracted to cooler stator windings. Cosmic rays help increase magnetic flux hence torque. Same galactic cosmic rays cool poles, solar cosmic rays heat equator. Both solar and galactic cosmic rays oppose eachother. same reason earth poles have high magnetic field.
Sir question h sir ek baar ye clear ker dijiye ki transmission kitne voltages tak hota h or distribution kitne voltages tsk hota matlab sir hmey kese pta chlega voltage level dek ker ki ye transmission h ya distribution ek video m samja dijiye sir please 🙏🙏🙏🙏
Okay, noted! 😊 Waise ishe video ko bhi check kr sakte hain Yahn bhi thora Start and delta starter par baat ki hai. Which motor draws more current start or delta : th-cam.com/video/AUSntMkM7mI/w-d-xo.html
Ji aste aste har ek concept cover krne ke koshish kar rahe hain different different topic ke form mein, aap motor wali playlist jarur check kijiega already Kafi kuchh discuss kar Liya hai.

Sir u are great Sir,
Aap Toh Topp ho India ki ek matra Hope Ho🎉😊

Thank you sir,
Aapka video bahut hi usefull hota hai ham jaise electrical engineering students k liye
Sir please continue video dalte rahe 😊
Gjbbb sir thankyou so much sir very important information 👈👈❣
Very very nice video. your video helps a lot me and my friends. thank you so much keep it up.👌🏻🤗
Fantastic sir, by adding external resistance in the slip ring type induction motor can increase the power factor. 😊
Thanks for sharing such valuable content ☺️
❤️❤️
Thank you very much sir . Ek video transducer pe bhi banaye sir. Sir apke wajah se mujhe bahut kuch sikne ko mila . Aap mere liye Great teacher ho.
How much power factor increases, that means higher limit.
Also only p.f. is sufficient to increase the torque or any other parameter variations required.
Thank you very much
Very good explain .. Very simple... Now no confused... 👍
I have a doubt, If we apply external resistance then it will limit the rotor's current (by ohms law) which will further reduce the torque.🤔
Same question?
ohms law work in some condition..
You are right. When we add external resistance rotor current will decrease and power factor will increase till some value of resistance i.e., r2=x2. Untill r2=x2 the decrement of cirrent is less than increase in power factor so total power will increase. But when r2 is increased more than x2 the total power will decrease.
Final conclusion is resistance increase then torque also increase with rotor sleepring
Actually adding there external resistance to increase the torque in the starting condition only not always. So, when motor will run as it's full speed the external resistance will be terminated.
sir i watching all your video very valuable video , and learn many more Thanks for your efforts.. 🙏🙏😀

Heat always weakens magnetic field??
Thank you Sir.... Valuable for EE students...

Agar hum log external resistance ki nikal de aur uss jaga pe ek drive install karke let ek Crane ki chalaye toh starting torque kaise improve hoga can u explain.
Torque k equation me inversely proportion me R^2 hai uska kya?
appreciate your work bro.., keep it up, your explanation is unique
Bahut badiya video banate ho janab aap aap printing press machine pr banaye ek video
Sure, Noted! 😊
Hi sir, very nice explanation. I have 1 doubt , Tst ke formula me sX2 ka term to neglect ho jata h aur denominator m sirf R2 rhta h, to R2 to inversely proportional kyu nhi hua torque ko?
Sir sabhi videos par series wise 1, 2, 3 marking kar dijiye ta Jo step by step knowledge mil sake
Very very thank you sir to explain this topic 🙏🙏
Sir ji biot savart law ke upper ek details video banayie n
Motor ke stater ma iron ke pati keyou hoti hai
Great....Technical Answer............
If we increase the active power total power bhi toh badhega to kaise pf improve hoga
But Resistance badhane se current bhi toh decrease hoga n
Torque directly proportional current
Very nice and well explained !
galactic cosmic rays attracted to cooler stator windings. Cosmic rays help increase magnetic flux hence torque. Same galactic cosmic rays cool poles, solar cosmic rays heat equator. Both solar and galactic cosmic rays oppose eachother. same reason earth poles have high magnetic field.
What a great explanation 😮
Bohot achcha
Thanks
sir, rotor circuit me resistance add karne se power factor improve hoga but sath hi rotor current I2 decrease hoga. please explain.
Adding resistance is used only for starting. Later this additional resistance is not applied or removed during normal running.
Product of I2 and powerfactor will increase by adding resistance till r2=x2 because increase in power factor is more than decrease in current
Knowledge 👍
Sir mera ek question hai....rubber or koi v high resistance cheez .... maximum kitna amp current sahen kar sakta hai....
Ek question h sir
LT motor me CT ratio se realy ki seeting kese kre
Sir question h sir ek baar ye clear ker dijiye ki transmission kitne voltages tak hota h or distribution kitne voltages tsk hota matlab sir hmey kese pta chlega voltage level dek ker ki ye transmission h ya distribution ek video m samja dijiye sir please 🙏🙏🙏🙏
Sir video bna dijiye please 🙏🙏🙏
Neutral aur Earthing short hone pe RCCB trip q ho jati h detail me bataye ???

Super sir 🙏, thanks for it
Sir in some videos they are saying that as armature current decrease torque increase
❤
Sir rotor current decrease hoga na to torque badhega kya
Sir Star_delta starter pe 1 video banae full concept ke sath
Okay, noted! 😊
Waise ishe video ko bhi check kr sakte hain Yahn bhi thora Start and delta starter par baat ki hai.
Which motor draws more current start or delta : th-cam.com/video/AUSntMkM7mI/w-d-xo.html
finally I got the answer. thank you.
😊❤️
Sir rpm ke bare me bataiye
External box main electric kahan se aata hai ?soch soch dimag kharab ho ho gaya hai please help me
Sir आप three phase induction motor topic par pura vedio banao please.
Ji aste aste har ek concept cover krne ke koshish kar rahe hain different different topic ke form mein, aap motor wali playlist jarur check kijiega already Kafi kuchh discuss kar Liya hai.
Thanks 👍 sir
Nich
If we connect external resistance then are we not wasting electricity in the form of heat?
Yes we are wasting, thats why we have to cutoff the resistance after acceleration period
Tysm ❤️
Nice brother 👍
Now double cage induction motor is made for high starting torque
Nice video🥰
Rotor main electric Kahan se aata hai?
Starting current ज्यादा क्यो होते है
Sir, can we increase the power factor by connecting the capacitor instead of Resistance.
Capacitor takes reactive power bro.... So power factor will be less if we add capacitor or inductor..
👍👍👍
But resistance also reduce the rotor current .
😍😍😍😍😘😘😘
