सर जी आज तक ये बात युट्युबपर किसिने नहीं समझाई ,थँक्स सर
Aapne bhut acchi tarh se samjhya esse pale you tube par aisi video nahi thi
भाई आपकी विडियो देख के संतुष्टि मिली ।बिल्कुल डिटेल से समझाया है❤
Acha...smjate hai.....good..bro...
Excellent and very very useful details given by you. Thanks
bahut acha video hai
Nice video sir
Sir good vedeo
Sir osm best sir stator dekhke ciling fan Rewinding sikhaye
Bahut sundar
Thanks sir
Nice
सर डबल फेस मोटर को सिंगल फेस में रिवाइंडिंग करने का फार्मूला बताइए बहुत ही दिक्कत का सामना करना पड़ रहा है कोई बी वेंडर से पूछता हूं तो नहीं बताता है

Supar sir
Thank u nice video 👌
Sir 3 phase motor ch double delta or triple delta connection kasa karta na
Good formulla bara vai
Thank you
Nice
Which fan stator is better 12 vs 18
Transformer winding Karne Ka Tarika batao na
Iss par kaafi video bana rakhi hai
@@PerfectEngineer Transformer data kaise nikaalte hain
Good Evening.
Sir Iam very much impressed by your explanation .
Pls can u help me ,iam looking for low speed celling fan RPM 230.
Regards
सर जी हाई स्पीड सेलिंग फैन 6+6=18 स्लॉट का डेटा बताइयेगा क्या होगा
Meraj bhai 34 number elimuniyam wire se Pankha winding karen to kitne turn dalni chahie jisse pankhe ki speed sahi hai aur Garam Bhi Na Ho winding lacchi wali h
RPM increase karne ka formula bhi bataye.....
Sir RPM ka full form Revolution per minute he
Kahan se padhaai ki Hai sir aapane Maine ITI aur diploma donon kiya hai aur RPM ki ful form hamesha round per minut hi padhaayaa gaya hai aapane kuchh naya Bata Diya
Aur Delhi Pusa ITI aur Pusa diploma se
@@ankitnagora5161Rotations per minute is right answer! Revolution per minute it's for engines not for fans.
brother stator material, core size, wire number, number of turns change karnay say bhi rpm par farq paray ga... 18 pole k stator par mein 50, turns ki winding kar dun ... lekin number of poles to 18 hi hein na is condition mein formula kaisay chalay ga...

Sir Kannada people benefit🤗
keya matlab 12+12 K RPM Sab say zeyada hotay hein .... us par winding bhi 18+18 say kam ho gi magnetic field kam generate ho gi to rpm zeyada kaisay??
Jab number of pole kam hote hain to RPM jyada or pole jyada ti RPM kam hote hain
@@PerfectEngineer to brother wohi pooch raha hun aisa q hai ...technical way mein jawab dein...
Bro bataya to wahi tha but aapko simple bhaasha m samajh nahi aaya to technically samajh lo,
RPM nikalne ka formula hota hai,
N= F×120/P
N= Syncronus Speed
F= Frequency
120= Connection ki °( Digree)
Yani 360°/3phase=120°ka kond bana
P= Motor k Pol
Isiliye Formula hai
N= F×120/P
N= 50×120/12=500
To 12+12 k RPM hue 500 Ye Syncronus Speed hai Ab Load pr RPM bachenge
500-5%=475
475 Motor k Standard RPM ( Speed) hai
Bro isse jyada ab m nhi samjha sakta 🙏🙏🙏.
@@PerfectEngineer ghussa hi kar gaye aap to brother..phir bhi wohi sawaal hai aap ghaur say nahi parh rahay.... aap technical way mein formula samjha rahay hein working nahi... mein yeh poochna chah raha hun k theek hai rpm 14 k sab say zeyada hon gey lekin phir hum 18 ka stator ya 21 ka stator q banatay hein 14 ka hi laga laitay hein winding bhi kam karni paray gi waqt bachay ga... rpm bhi zeyada milein gey... 36 ya 42 slot stator q banatay hein phir hum?

Dear friend
Pole and coil is not same thing
Example
a motor in 12 coil but it Motor rpm 1440
So please tell me how it com
Because
it Motor 4 pole
Each pole 3 coil set
Don't confuse your viewer's
Iska matlab science ke formule wrong hote hain
12 coil 3 phase ki motor m hote hain
12/3=4 pole
Use formula
N= F120/P
( N=50x220/4) = 1500 RPM
1500-4/5%= 1440 RPM
Kahne ka matalab ye hai ki 12 coil ki 3 phase motor k ek circuit m 4 pole hote hain

Let's we have an induction motor with p=2 and feed it from 50 Hz grid. Then we re-connect the winding coils to arrange p=4 and feed if grow 100 Hz grid. Are performances of these two motors different or the same?
Please note excluding frequency and inter-coil connections all remained the same.
It depends on the required speed. n (rpm) = (60 x f) / N where
f = frequency and N = number of pole pairs.
The 60 is there to convert from revolutions per second to revolutions per minute as the frequency is in cycles per second. Pole pairs is there because that any pole must be constructed in a pairs top and bottom / left right, so with one cycle it will move half the distance.
If you are using 50Hz and have a two pole motor 60 x 50 / 1 = 3000 rpm. The induction motor will run at a slight less speed due to "slip" which is what gives the motor its torque. For example 5.5kW, 400v, 2 pole motor will run at approximately 2880 rpm.
For a four pole machine, 60 x 50 / 2 = 1500 rpm so the same size motor at 5.5kW, 400v but 4 poles will have a nominal speed of 1500rpm but will run near 1455 rpm.
👉When selecting a three phase motor,
the number of poles is chosen to achieve the speed of rotation that you require. Here are two tables, one for a 50 Hz power supply and one for a 60 Hz power supply:
The formula is n = 60 x f /p where n = synchronous speed; f = supply frequency & p = pairs of poles per phase. The actual running speed is the synchronous speed minus the slip speed.
For a 50 Hz three phase supply:
2 poles or 1 pair of poles = 3,000 RPM (minus the slip speed = about 2,750 RPM or 6 -7% n)
4 poles or 2 pairs of poles = 1,500 RPM
6 poles or 3 pairs of poles = 1,000 RPM
8 poles or 4 pairs of poles = 750 RPM
10 poles or 5 pairs of poles = 600 RPM
12 poles or 6 pairs of poles = 500 RPM
16 poles or 8 pairs of poles = 375 RPM
For a 60 Hz three phase supply:
2 poles or 1 pair of poles = 3,600 RPM (minus the slip speed = about 2,750 RPM or 6 -7% n)
4 poles or 2 pairs of poles = 1,800 RPM
6 poles or 3 pairs of poles = 1,200 RPM
8 poles or 4 pairs of poles = 900 RPM
10 poles or 5 pairs of poles = 720 RPM
12 poles or 6 pairs of poles = 600 RPM
16 poles or 8 pairs of poles = 450 RPM
To determine the number of poles, you can read the data plate directly or calculate it from the RPM stated on the data plate or you can count the coils and divide by 3 (poles per phase) or by 6 (pairs of poles per phase). Where the power of the induction motor is constant, the torque increases at the rate that the speed decreases
👉 I hope you understand
