Really great video....... Good luck !!!

[@janami-dharmam]

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.

Big respect sir. Tnx for your value knowledge

[@uryyuryy7336]

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

[@kheavmady8780]

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

[@Yoyo-me]

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...

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...

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.

[@antoniosilva5933]

Excelente ideia usar três núcleos fica melhor a distribuição do peso. Pois ficou longo o transformador . Fica também com pouca altura . Muito bom 👍👍👍👍

[@Dave_en]

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.

[@user-rj2pm8nu5t]

Пропитка слоёв на таком каркасе обязательна. Потому что, очень быстро произойдёт пробой изоляции между витками. Кто разбирается в этом тот всё это знает. Удачи

[@shuashuashua1]

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.

[@suryapatnaik5720]

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.

[@edwardbartolo6382]

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.

[@adam207321]

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

[@peterream9437]

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.

[@cartoonfunhindi2024]

yes there's is formula for number of turns it's depends on you that how much power you need

[@user-in8gu6hg8z]

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.

Wrapping the bobbin with masking tape is a poor choice - use Mylar tape, it’s designed for high temperature and high voltage.

[@newtechinvention105]

Crative and good video, thanks for sharing

[@RovereTano]

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

[@jocionemachado1736]

Amigo, falo aqui de Fortaleza CE. acompanho seu canal e gostaria de tirar uma duvida. Preciso para meu projeto de amplificador um trafo com as seguintes características. Primário: 110/220V. Secundários: 35V 0 35V 5A e 15V 1A. Quais seriam os cálculos do trafo?

[@electronicsdiypcbdesignpro6881]

wonderful transformer making for powerful amplifiers

[@waterfuel]

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.

[@samohraje2433]

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

[@elrusosolda5386]

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.

[@youssefdirani]

Why ?

[@Dave_en]

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

[@ronniepirtlejr2606]

What does this to increase your amperage?

[@piotrjader8914]

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

[@yashdodia8048]

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

[@junexjeyesmallbrain3477]

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

I have made a Transformer like that how many years ago, but the result ???, not effective !, Only 50 - 70% of the output, the rest is in the form of heat loss .... My experience is for more than 20 years, ... Thickness Effective Kern must not be more than 2 times the size of the Kern, for example the size of the Kern E25 (2.5 cm), the thickness of the effective 2x 2.5 = 5 cm.
