Hey did yours overheat? Mine did after a few minutes, and after I thought about it, microwaves are usually only on for a few minutes to heat your food, so they might not be designed to run for long periods of time like if you were to use it to charge batteries for example. Do you think if I were to add extra windings to the primary it would help stop it from overheating?

I found that putting a resistor on the positive output limits the current draw and after that the transformer was warm but not hot.

Wow another great demonstration your about the only one from you tube that is real and not fake

It can be a wonderful tool for running the cars during a battery charging performance

this is real, about to go try it out. Thanks man.

Wow crazy stuff like👍👍

Great skill u make it look easy other people make it difficult to understand

Nicely done

Ok selber gerade ausprobiert , gute Idee !

May be the fun can't cold that transformer, use water cool with motor pump or freezer system cooler

Very good project 👍

Very clear and clever ... thanks

muito bom

BRAVO how mani turns you made this secundary.Thanks

Good idea 💡

Excellent presentation. 👍

Your project is very educational, it can also be used as a battery charger, the transformer has very good amperage and with the two full wave rectifier diodes and the capacitor, the output of the 12 volts ac transformer is increased, transforming it into 17 volts dc, thanks Greetings from nezland City Mexico.

Nice project, well done video 👍 Did you find the transformer issue ? I believe it's from the eddy currents caused by the loose plates. Compare this transformer now, with how it was BEFORE tear down. The plates are compressed,welded, and resin sealed under vacuum . But for now you could bolt it together using high grade non-magnetic bolts.

Esxelente video

Verry nice. You are not need a fan. The problem is the copper isolation and occuped space of secundary coil.

Ola .. saludos .. desde Quito-Ecuador . Muy bueno lo que ase ... pero una pregunta .. Cómo es que se llama es coso azul... Y como puedo conseguir. . Los motores .. Como se llaman.. Y de cuantos voltios es el motor. . Gracias .

Put this transformer on a aluminium plate and install some peltiers plate in paralel/serial to take the heat from transformer and convert it in to eletric energy and the same one you could feed a cooler .

Hi buddy, I really like your projects and also the detail explanations that you are doing. Kindly provide some schematic diagram too if you do any further projects.

By far the best build for a welder that I have found. Great job, one question. Since I am here in the states what would I get if I connect to 110v instead of 220v or do I have to connect to 220. I have a switch the I salvaged from a computer power supply that you switch from 220v to 110v, will that help? Thanks in advance and again great viceo!!!!!

You will get roughly half the voltage output. The voltage in the video is too high for a 12VDC system, so first of all reduce the 22 turns to more like 17 or 18 turns. Now double that, to give the same secondary voltage at half the primary voltage. This would also increase the primary circuit current by a factor of two, for a given load. It is simple ohm's law arithmetic here. When you get to high school you can learn stuff like this in physics class. If you are already out of school and you missed that, get a good book on electricity, magnetism, and safe wiring and electrical practices before you plug anything in to anything.

It can be use for welled

Reducing the number of turns of the secondary will drop the voltage to get 14v?

These kind of motors requires a great current. From where you get this high mfd capacitors will you be able to keltron capacitors in this microfarad.

Great! Hight current with microwave transformer

thank you for really fantastic video. But you did not say anything about capacitor rating. will you please say that?

Can this capacitor handle 100A then?

you cann t use this power supply for long time cause you use wire with plastic insulator. You can use varnished wire . The current you gated is only 25A as a max . you can use the law of transformer to know the volt or current from secondary side V1/V2 =I2/I1

A consultation with the system can I start my scooter or which one would have the necessary current to start my scooter that my battery discharges

you can put the transformer inside an airtight container and filled with vegetable oil such as linseed oil that is used for wood to protect it from heating

Mr. Electron the 750Watt Microwave oven has microwave oven transformer (MOT) core that is calculated for the 375Watt RMS out put power. So 375Watt : 10.5Volt = 37Amp Max Output current. That why it has a current shunts build in between primary and secondary coil.

sorry I am new to electronics. Can you clarify why transformer was used?

Why a bldc fan for cooling? We can use high speed dc motor as fan..... But literally very good vedio. Next time please try the same with normal transformer and a few more turns of secondary thick wire, let us see what happens to the heating problem. I will be very eager to see that. Very well done. Congrats....

Will this work with 120 volts AC?

Can we convert low amps into higher amps ?

Ok felicitari

What would you get if you converted a 240 volts a/c to DC and how would you be able to increase the AMPS on THE DC output

@TheChrisey

4 жыл бұрын

You are always limited to the capacity of the primary winding. A microwave is generally designed to run slightly below 1kW. 100Amps * 12v is 1.2kW. I highly doubt that this old microwave transformer was designed to handle that, thus it would blow up eventually. To increase the amps, decrease the number of winds on the secondary. It'll give you lower voltage but higher current. Also the wire used in the secondary in the video will never take 100Amps lol. This video is ridiculous

Just remember that microwave oven transformers are made on the brink of saturation, they are not meant for continues operation out over 15 minutes. They will destroy themselves from heat over a longer period of time. If you want to avoid this, add some more primary turns to lessen the Volt/turn product a bit.

Nice project. I measured a MOT saturation curve, they are deep into saturation (maybe 100 VA) at nominal input. Another solution is to use two identical MOTs with primary windings in series, so that each one operates at half voltage. You can then wind the secondaries and connect to suit. This configuration would run much cooler even if the primaries are aluminium. I would suggest using much thicker copper wire if your target is 100A continuous capability. I have a YT video to show over 1000A from a single MOT transformer with a 2 turn secondary when I paid attention to keeping resistances low. I use it for wood branding art.
