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.
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.
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...

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.
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.
It's just smaller high frequency transformer with feedback winding If you don't know you shouldn't be messing lol and there's loads of videos about it... FFS you lazy fucker
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.
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
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
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.
This transformer has power ~1000VA. For primary winding we need a~ 3mm^2 cooper wire. On this moovie I see max 1mm^2. It's a triumph of form over content
@@mujianto1420 aku masalah bikin trafo mulai ukuran kecil 1a - 15a aku bisa ngitung cara rumusnya. Klo ini aku belum pernah bikin trafo memakai gabungan kayak gitu mas broo. Nanti akan ku coba beli trafo dipasaran 5 biji mau aku gabungin juga jadi satu dirangkai ulang.
I thought that the transformer formula was in metric, such as core square CM. Also gauge of wire formula is as 700circ mils times current times duty cycle. If power not on all times during time period , then the gauge wire can be smaller. circ mils times % duty cycle. Also, if choosing a LARGER core than required, then there is less turns that have to be wound on bobbin because of formula. Assembling a low frequency transformer with E and I laminations can be interleaved, or separated , so as the top I set comes off, so as bobbin quickly removed for rewinding. The separate laminations type requires strap over unit to hold together. The old style radio chokes were like that method.

@@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)
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.
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.
Que sentido tiene esto? lo unico que veo que aumenta es el peso y el volumen del transformador, si no aumenta el diametro del cable del secundario, no va a aumentar el amperaje.

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
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...

При такой длине провода надо пролачить на горячую, а вторую обмотку мотать сразу двумя проводами, чтобы сопротивление было одинаковым

super bro good idea before iam also done same this for 45 0 45 v amplifier

Good job! total VA ratings of the 2 transformers will be the VA rate of final product.

Very informative I expect this type of evaluation by the way I can earn money.thank you , God bless you.
Excelente ideia usar três núcleos fica melhor a distribuição do peso.
Pois ficou longo o transformador .
Fica também com pouca altura .
Muito bom 👍👍👍👍

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

What does this to increase your amperage?
super! bravo!
O transformador ficou desproporcional! O comprimento não deve ultrapassar o dobro da largura do núcleo! Seria melhor fazer dois trafos! Abraço!

He uses Winding Rule '42', A lot of guys use the rule similar to this one.
300 winding :220V=1,36 winding 1V, ....35Vx1,36=47,6 (48 winding)
Thats gangster that would make a sick 1 to 1 isolation core

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

sensacional.
Sir can you explain all in other vid?
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!

thank you useful
42/32.5 = 1.29 means 1.3 turn per vot.

For 35 volt tranformer need 45 turns
