Good job. Two suggestions: after you finish the windings, soak the bobbin with the coils in varnish and allow it to dry completely before you insert the lamination. Otherwise the coils can make some noise. second: The lamination stack should be pressed in a vice and bolted very tightly otherwise some magnetostriction hum will come.
if m not wrong, each tranformer is a step up 12v to 220v. Just connect 2 primary of them in series to make 24v and connect 2 secondary of them in parallel. No need to rewire
Nice work.!! But it gives 32-0-32 instead 32 0 35... why ?? Coz u added 38 (362+30) extra in primary but not in secondary... use extra round in secondary also.. in order to get 35 0 35 in working amp it should be 37 0 37 without load...
Пропитка слоёв на таком каркасе обязательна. Потому что, очень быстро произойдёт пробой изоляции между витками. Кто разбирается в этом тот всё это знает. Удачи

can i have a question? on how to identified the gauge/size of magnet wire that can used on winding the transformer? before i'll make this kind of project but i can't finish it due to the size of magnet wire's that i used is big instead of 50v-0-50v target on dc output the result 32v-0-32
But according to design principle you have to avoid making stack height to width ratio > 2. I have found that the square core has the best fill factor and most efficiency. Though you could make upto 1.5 ratio to match the desired VA of transformer. These kinds of design makes low efficiency transformers with more iron losses. Better use bigger core to increase power handling capacity.
You should add insulation between layers, shortcircuit between layers is common problem in transformers even with good enamel on copper. Ofcourse this insulation gonna incerase Your transformer stray capacience but its worth to add it if frequency is low (when You made it by hand coz You have no option to vaccum impregnate it) Also Your insulation tape looks like masking tape... never use it to insulate windings.
Sir agar ham isi bobin ko 13 cm k bajye 15 cm karke 45 0 45 banye to kitne turn primary aur secondary turn dalna padega please reply jarur dijiga ham inzar me rhenge
Además para tanta "potencia" uso alambre muy fino, y tenés como desventaja la reglutancia magnética (distancia que recorre el magnetismo) así que además de menos potencia menor rendimiento.. hubiera sido mejor usarlos con primarios en paralelo y hacer un arreglo serie en los secundarios.
There's a formula for the number of turns and wire dia , for primary and secondary windings on a transformer. Not something you would really want to mess around with , unless you understand the basic principles of electricity.
What about using the stator iron core of an electric motor? With that you get a toroidal iron core. All you would need is to cut off the edges of the innerside grooves where the coils are installed. That way you will have a ring core which you can use for a toroidal transformer which is known to be better than other transformers.
The laminations are facing the wrong direction and also the inner core of a induction motor is not suitable for a transformer because of the actual material used for it. Remember a transformer is not as simple as a lug of iron and copper wrapped around it
Wrong calculations ! What is the watt's of it? He will gets 140 watts .some of the input energy is consumed by the device itself as it converts the energy into another form, typically heat, and that energy is lost.
А чего ж мотает проволоку в ручную? Сделал бы приспособу для перемотки катушек..... и внутрь катушки надо деревянный брусок влаживать, чтоб катушка не ужималась внутрь. Пару раз уже было - намотал проволоку, а железо вставить не могу, потому что катушка вогнулась.
И к тому же, так как он мотает, он не может натянуть проволоку как положено, из за чего при работе трансформатора возникает микровибрация и со временем изоляция на проволоке сотрётся и произойдёт межвитковое замыкание. Ляпов тут у него вагон, но задумка не плохая.
bro for frimer coils, 1mm wire in double or in parallel so that 2mm will be rolled together at the same time or not, then the N ends are joined with N and the L ends are joined with L or each end is joined thanks.
@@retsain ... dont think in amperes... try to focus on watts...so, the volt-ampère (VA) rating is directly proportional to the product of core area and the area occupied by the wires (copper areas)
A person who eats bread and transformers for breakfast hehehe. But shouldn't you also take into account the height of the winding? Use a plastic hammer, with the iron one you ruin the sheet metal You are wrong by 2 volts in the secondary because you have not taken into account the increase in size that the primary gives. Anyway Bravo

Big respect sir. Tnx for your value knowledge
I learn many things about transformer making .this is one of the best channel I found from youtube about electronics .thanks for your videoes sir .
Hello Hello 😃😃😃😃
Yesa video hammer pure RUclips channel par nahi dekha nice video
No one make this transformer in online but i have made one 😍 From this

Very good! I have done this o lot of times 😁.
When the support of few transformers get burnt or destroyed, remain the E+ I parts...
Your work is out standing .
Very well done my brother.
I hope is it very havi .
You are creative, sir ... I watched this video until it's finished ...👍👍
Muchas gracias!!!el truco de poner cinta por cada pasada de alambre en los extemos de la formaleta me ayudo a que el bobinado me ocupe menos espacio

Excelente ideia usar três núcleos fica melhor a distribuição do peso.
Pois ficou longo o transformador .

He uses Winding Rule '42', A lot of guys use the rule similar to this one.
Bhut badiya idea h 👌👌👏👏

why not,please? what to use then?
Thanks very much I got very good idea
no comments?? bet im the first one eh.. nice build btw.. just have one question is it more efficient over toroidal??

Dude this type of transformer you've made is less efficient than 3 transofrmers you've just used to make this one.

Why ?
@@youssefdirani practically the fill factor is less in this stack height to width ratio. Best practice is to use square core if possible.

yes there's is formula for number of turns it's depends on you that how much power you need
Does 42 also applies for the Philippines?

Pro total primary winding terns how much.
U have not specified used wire was aluminum or copper?
U r using aluminum wire for both primary and secondary winding, that's it's easy to wind. Normally it's hard to wind 18gauge copper wire.
He is the king
Is it for sell? I need one like that but primary 110vac.

How many output Ampears give In This video Transformer .
Average 140 watt's !
Wow bro brilliant
300 winding :220V=1,36 winding 1V, ....35Vx1,36=47,6 (48 winding)
This is what you do when you don’t have RadioShack in your village.
Hey you said in this video that Ac220v but actual ac220v is rms value so peak voltage around 300 so your winding should according this value 330v

What was the meter reading?
what is the size of the primary and secondary copper?
the iron core is too large The wire should be 2.2 mm if the wire (primary) 1.2 then the iron core is 18cmm2 (otherwise there is little space Üdvözlet!
A person who eats bread and transformers for breakfast hehehe.
But shouldn't you also take into account the height of the winding?
Use a plastic hammer, with the iron one you ruin the sheet metal
You are wrong by 2 volts in the secondary because you have not taken into account the increase in size that the primary gives.
Anyway Bravo
