- Speed control of three phase induction motor is explained in this video. Induction motors are the most poplars motors due to many advantages like they are robust, cheap in coast, require less maintenance, can work in polluted environment. The methods used to speed controls are;
1) Stator Control
a) By controlling voltage though auto transformer
b) By controlling voltage through Rheostat
c) By controlling Voltage through ac voltage controller
d) By controlling frequency
e) Constant V/F control
g) By changing number of Poles
2) Rotor Control
a) Rotor resistance control
b) Cascade control
now i finally find one of the best channel for electrical engineer.
Superb explained sir kaas ki aap se pura electrical ka subject padhta Ur amazing all doubts r clear
Sir aapki hur vedio bhut achchi h sb bhut achche se samjh aata h I'm wetting for your next video
I'm desperately waiting for your videos sir because it has its own quality and awesomeness than other videos.
SIR, great lecture Maine 1st video me hi channel subscribe Kr diya, aap 1or 2 question bhi liya kijiye ki application kaise krna h. 🙏🙏🙏🙏🙏🙏🙏
Way of explanation is very good 👍
Kis device se control kaise kar rahe h or kya kar rahe h, ye chiz mujhe bahot acchi lagi,
Please ek video direct of indirect field oriented control (FOC) pe v lecture banaye ...
Very useful video. Thank you.
Very useful,thank u sir.
Dete to bhut accha rehta sir and thankyou sir
Dil se Shukriya :)
Amezing 3d and explaination
Nice explanation
Best video sir 👌💯
awesome video
Thank you brother 👏👏
Nice explain..sir g thanku so much
Thanks sharma ji
Transformer m konsa test krne m 2 transformer use hote...sampner.test .short circuit test..open circuit ya phir direct loading test
Thank you bro
Ek qustion tha ki sbse km luman efficiency konse lemp ki hoti.
Hellogen lemp.. florocent..sodium or murcury lemp
Thanks sir❤️❤️🙏🙏
Video bhai Aachha hain
सौरभ शर्मा जी आपने जो भी इलेक्ट्रिकल के बारे में व्हिडीओ बनाये है, वो बहुतही अच्छे हैं, इसें इलेक्ट्रिकल के विषय समजने मे बहुत आसानी हो गई है, आप भविष्य मे ऐसें व्हिडिओ बनाते रहे, मेरी तरफसे आपके ये सामाजिक कार्य की बहुत सारी शुभ कामानाये देता हूं.
Please tell us all definitions of dc machine as pole pitch , single double layer , simplex duplex windings
Ok nice topic, thanks we will make a video on that
Sir very nice vidio
Sourav ji, control wiring and interlocks ke upar video bana payenge plz.
Thanks sir 😀😀
Thanks sir
Very good
Single phase and three phase with giving constants value
Thanks for your support
Ek qustion tha ki..sbse jyda age konse cell ki hoti.option the...solar celll ..led acid..nikl cadmium..or nikl alkine
we apply low voltage by auto transformer ,this time may current high
winding may be burn or not?
That is why we apply low voltage at starting to prevent the induction motor from drawing high current
Ek qustion tha ki universal motor motor ki spehere control ki konsi methods nhi h
Tq sir
shukriya.I want a motor capable of dragging/pulling or lifting a persons weight through a pully connected to shaft.weight within 75 kg.how to reduce speed of a motor to 10 or 15 rp minut?will u inform?or if available in the market pl.mention detail.that pully is tied to shaft of that motor should be able to lift up to 10 or 15 feet slantly by 60 or 70 degree like 10 or 9.30 pm (small angle in a cloak
Sir. If we feed three phase supply to a stator without it's rotor.we know it will burn but why pls derived briefly with mathematically ..
I don't think so,
In absence of rotor we can apply rated voltage to the stator it will not burn, because it always have sufficient resistance and reactance to maintain rated current.

Sir sabhi type ki motor ka video bna dijiy please
JI
Sir aap kuch electrical engineering machine me se puche jane wale question ka bhi ek video bna
Single phase motor m use rotor konsa
Please make a video on this topics
Sir cable contecto circuit breaker farmula ke aadhr per
Sir want know the formula to calculate turns of induction motor
👍
Sir kya ham 1 phase induction motor ko capector ki jagah bade recifier ko reverse me lga kr self start bana sakte hai ?????
Please reply sir ..
Capacitor or rectifier dono ka work bilkul different hai, mujhe nahi lagata ye mumkin hai. fir bi mauka mile to aap try karna, lekin saavdhaani ke saath
Sar all machine ka part kiss kiss material ka bana hota hai is par lectures banaye
🙏
Full information dete jao aisi animated video bnate jao
How to change no. Of pole by switch?
Sir motar kitane prkar ke hote hai sabhee par vdo banaie
Ji ham saari motor ko cover karege
10 cell 10 ohm resistance sb parelll m jude sbka eq.resistance btana tha
Sir jese ham motor k name plate may 50Hz likha jata hai is ka matlab ki 50Hz frequency may chalne wala hai. To sir ham jab VFD laga kar frequency Chang karte hai to moto kese chalti hai...
Bhout accha question
VFD sirf frequency hi change nahi karti, wah saath me voltage bhi change karti hai.
Frequency km karti hai to voltage bhi km karti hai, or frequency badhati hai to voltage bhi badati hai.
Is se motor ke upr koi bad effect nahi padta
@@sourabhsharmahindichannel3000 thank you sir...
@@sourabhsharmahindichannel3000 sir app utility maintenance k bare may video upload karo. Jese ki industries may kese maintenance kia jata hai. Or us k sath interview questions bhi discuss karo.
Sir Torque ka equation galat hai
Equation mein niche rootover(√) nhi hoga
At 3:52 , the equation of torque is wrong. The denominator shouldn't be in under root.

Sir paper ka level bhot moderate tha..kuh qustion toh smjh hi nhi ay

Sir apko tower cranes ki motors ka koi idea Hy k wo kaise Kam krti hn unki speed ko kesy manage krty hn oska ka Kia method hota Hy muje reply zaror kren or kindly apna koi WhatsApp send kren
Drive me bare me kuchh jankari hain to bhai baatwo
Auto transformer kaha milega
Mere ghar pe hai ake leleo 😂😂😂😂
Sir ,pdf provide
Saurav what is your email
Dso na putt
English very charge.
Your torque equation is wrong
