You mean the number of turns? If yes, it depends upon the size of your transformer inner core, Just follow the formula that i have shown in this video.
It depends on how many watts your pump can operate. For this pump, it can operate 4 watts, so i used #38 wire. Each wire size corresponds different wattage. You may use google for the wattage of each wire size.
@@ronnelmindo898 if your core is not the same as mine in this video, you should compute it using the formula I used in the video. Do not follow the number of turns I used in this video because the size of the core we are using is different.
Wonderful I have a DC aquarium air pump the circuit board is damaged I tried to connect the transfer directly to 4 v battery but I found interrupted moving and didn't run well do have any idea to make it run
The best way is to repair the circuit board. You must test all the electronic components with a multimeter and replace those faulty componets. Just test the voltage rail from the battery socket going to the motor. What is the recommended operating voltage of your DC PUMP?
@@ronron322 the old battery was 3.7 v I'm using li-ion .the electronic components are damaged and the transformer doesn't work well when I connect it with the battery
@@captmohelsaadany6751 The transfomer should not work if you directly connect it with the battery. The transformer needs a switching TRANSISTOR to oscillate in the primary winding in order to produce the desired voltage in the secondary winding. The Transformer cannot operate without a ciruit.
@@jingleoropa1524 it doesn't work if 4620 turns doesn't fit in the inner core, i don't really know if avr transformer windings will fit. Just try to use the primary winding of the avr.

What is 42
@@atishubhamkumar9404 42 is a constant number and cannot be changed.
What is wire number sir
sir, i want to question forconstant 42? diameter wire or what?
Seriously what I wanted to know you gave me each and every details thank you so much sir
Sir. Where did you get the 42 in your computation?
Sir how many times we had to make round for single outlet pump
You mean the number of turns? If yes, it depends upon the size of your transformer inner core, Just follow the formula that i have shown in this video.
@@ronron322 yes yes i was asking about that and 🙏🙇 thx for reply
Where can i buy it my pump is not working anymore
Which is the right specification of wire to be used ?
It depends on how many watts your pump can operate. For this pump, it can operate 4 watts, so i used #38 wire. Each wire size corresponds different wattage. You may use google for the wattage of each wire size.
Is 50grams of #32 will fit for 4620 turns?
if your transformer is big enough it should fit.
Bhai transformer kaha mile ga
I have 25 gauge copper wire, can i use that for winding ?
If i can do so, then how many turns will be needed or how can i calculate that ?
Thank you 😊
220*50=5500 turns
Constant what does it mean?
Please help me
fixed value, a value that does.not change.
@@ronron322 o me I have a sobo sb-988 but it got burnt ,How do I re-coil the transformer?
@@ronron322 How many mm wire and how much trans will please tell me sir?
@@সখেরবশেকরেছি #38 wire. just compute the number of turns using the formula that i used.
Clearly explanation, but what is the wire diameter that recommended ?
Just identify the current consumption of your device. The airpump in this video is rated 4 Watts and we are using 220V in our country.
Current = 4 Watts / 220V
Current = 0.018
Wire Guage = 39

if i use gauge #39 or # 38 how many turns if my pump transformer is 8 watts thank you
Use bigger wire for 8watts, maybe #34, same number of turns.
@@ronron322 my core is 1.7 cm x 1.7 cm would #34 will fit doing 4620 turns???
@@ronnelmindo898 just use 36 or 38

The constant should be much higher than 42 because this core has a big air gap! The reactive power would be unnecessarily high!

If i used 36 wire gauge no. How many turns need it
Still the same. Just follow the computations for the number of turns in this video.
I will do 4620 turn,i have same transformator but when she work is very very hot, i think that will burn.why ? I think i need 5612 turn of 50 hz
Which gauge wire used
You can use gauge 38 or 39.
Sir i want to know that you cut the wire between 1k, 2k, 3k, and 4620
No, its continous. And if your wire is shorter, you may extend the wire and connect with another wire, you may solder both ends and cover with a tape.
I put those markings 1k, 2k, 3k etc. in case i forget the count, ill just go back to those markings.

Just follow the same formula, as long as the thicker wire fits, it will be fine.
@@ronron322 so i just make 4620 turns?even its thicker?

Thank you.
Don't can long time bro you coil so heat because coilwire medium.
Ggs bro
Damn....too much work!! Better to just buy another one. Lol!
This is unrepairable.
Continue round ya insulation and continue round 1k,2k,3k sir
Just continue, do not cut.
the formula is 7.5 not 42
It is 7.5 if the core dimensions are in inches and 42 if the core dimensions are in cms
कुछ समजमे नही आता है आप बातोंसे बताओगे तभी समजमे आ सकता है
Sir i have the 42 number wire.. Can i use it,and how many turns i need?
same number of turns.
