Transformers

I'm building a power supply for a cnc router powersupply. The output has to be 36 volts at 12 amps. I'm going to use 6 of the 25.2 volts, 2 amps transformers at radioshack (I have a coupon). When I rectify it it should be about 36 volts. Couple questions about transformers 1) don't transformers essentially short out an AC socket? I don't wwant to start a fire. 2) how can I have a LED indicator that indicates that each transformer is working? I don't want to use a huge resistor, because that seams inefficient. 3) how big of a filter capacitor do I need? I have a 33000uF capacitor, think it's a bit overboard? I know I need at least 4800 uF for just stuff like motors, but the only capacitors I have that works above 50volts is that capacitor. 4) can you connect AC in parralel? Can someone draw be a diagram?

Transformer

Hello everybody! I just need some help with an electronic project I was doing-I need to desolder a transformer from a camera flash circuit, but every time I try with a new circuit, it always melts or the component leads fall off. I have included some pictures of it, maybe someone could identify the kind so I could buy it at an electronic retailer? It is meant to have 5 leads, with 3 on one side and 2 on the other. On a technical reference it has 7:3 coil ratio. Any help would be greatly appreciated. Thanks!

Transformer question?

I took a part an ooooold boombox and got some cool parts from it, one of them being a heavy, good-sized transformer. The boombox was using the transformer to step down the voltage before rectifying it.(Right before rectification it goes through a 500mA fuse if that helps...) From what I can tell, the mains power is connected directly to the transformer. I tested it with low voltage AC source and found that it is roughly a 10:1 ratio transformer. I wanted to reverse this and use it as a step-up transformer, but I don't feel comfortable hooking it up directly to mains in case it draws too much current and flips a breaker or something (I read a biography of this one dude and when he was a kid he tried to make an electromagnet using mains power.... knocked out the power on the whole block and the police came...). Will it draw too much current putting it on the low voltage side? I saw one guy say that using a 50 ft extension cord will prevent it from drawing too much. Will that work? If not any other ways? (or just not worry about it?) edit: It is roughly the same size as this one  https://www.instructables.com/id/LM3886-ChipAmp/

Transformer modification? Answered

2 questions about transformers: - If a certain transformer (let's say, for a power amplifier) is needed, and for example, a microwave transformer is available, can the steel frame be cut to take out the secondary coil, to be replaced by a new one, and subsequently be re-attached (by clamps or so)? Would it need some treatment, like putting varnish, or oil over it?  Would this cutting and re- attaching cause a loss in efficiency, or cause heat build-up? Would it cause more noise in the output? - Some amps have a toroid transformer. Is this just fashionable or is it for a reason? Some industrial amps use sheets of copper instead of wire. Why is this better for industrial, why, and if not for common stuff...?

Transformer Question? Answered

Hi, I want to plug this transformer I have into the wall to be able to use its output to power several of my other projects. I need a way to limit the current from the mains power supply into the transformer, it has to be limited to about 1/2 an amp. I really don't want to lose any voltage though, and when I use a resistor to limit the current it sucks down all the voltage and overheats. I really need some help with this. Thanks

Transformer Technicalities?

Hey guys I need some help from the experts. I am building the microwave transformer ark welder instructable. I have acquired my microwave transformer, and rewound the secondarys. Now here's where it get interesting. I stay in South Africa, and we have 220v, 15amps coming out of the wall. So I figured with so much wall power I probably only need one transformer, cos I already have too many amps (on paper). So from what I understand, I will be putting 3300watts(220v*15Amps) into this transformer. Another interesting detail is that I think my transformer has 200 turns! I put 16 turns on the secondary (although there is space for more, I just don't have a piece of wire long enough). Which means that my out put voltage will be 17.6v, and 187Amps! Ahhhhhh!!!! If I wind a few more turns on the secondary, I could probably squeeze 25 on there, that will bring my output voltage to 27.5v and 120 amps. Which seems like quite a lot? So here's my question: Will this work? If not, and things go bad, what will happen? Is there any chance that the primary coils will melt, or is it only the secondarys that will do that? I don't really want to destroy my transformer, because they are really hard to get here. South Africans won't give you snow in winter. I had to buy a broken microwave! One idea I had: I have a single coil wrapped around a plate iron core, it looks just like a transformer but with only one set of windings. The thing is as big as the microwave transformer, its wire is of a slightly thicker gauge, and it probably has about 600 turns on it (it belonged to a florescent light setup). I thought I could connect this up to the secondary winding, maybe it will bring the amps down, and also serve as an inductor/ark stabilizer. But I'm just guessing, I'm a complete noob to electronics!?

Transformer current restriction? Answered

I am aware mostly how transformers (AC - AC) work, but I am lest informed on a few key parts.  I know there is a direct relationship between windings and voltage as well as an inverse relationship between voltage and amperage. The thing I don't understand is what limits the current produced by the transformer.  I know you can keep droping the secondary windings to increase amperage, but eventually you get to a point you can no longer do that.  To overcome this one can use three sets of windings wired in parallel which will retain voltage but increase amperage.  The amount of amperage is still limited to the maximum throughput of the primary, but how do you actually find this out.  If one wanted to make a variable current AC welder, it would be relatively easy to predict the voltage, but establishing a potential amperage is more difficult.  What actually establishes the maximum output of a transformer because in some cases the max current is reached long before the actual failure, and is there a way to predict the end product.  P.S. I am not looking for the answer they use voltage/current limiting circuts ect...  I am looking at something like a pole pig which maxes out output before internal failure and contains no additional circutry, not a wall wart

Microwave transformer electromagnet?

Hi so I was bored and decided to make an electromagnet out of a microwave transformer by taking the secondary off and keeping the primary. I hooked it up to some 9v batteries and stuff but it wasn't that strong so I researched it a bit and found out you can hook it up to the transformer input voltage (which was 240v AC) so I did but when I turned it on it made this very loud buzzing noise and I thought I saw what looked like flame in the socket. I turned it off imediately and unplugged everything. Whatever the magnet did must of been strong because it broke itself apart slightly. I tested the sockets with a multimeter and they still say 240v but I just want to make sure I didn't do anything bad to it. Also did anything actually go wrong or was this all meant to happen?

What is this weird transformer?

I opened up a microwave hoping for a microwave transformer. But instead i got this weird looking one. i was hoping someone may be able to identify it and tell me if i could use it for a tesla coil. also, there was no capacitor??!! the largest caps i could find were those three red ones in the pics. it apeared to have litz wire on the outside and normal wire wind on the inside. Numbers in it were - 97INV (im not sure if its a 1 or i)   and F69144TOAP and finaly   F607C.  Update:  ive now taken it apart, see picture. so, im guessing the litz wire was the primary (240v) and the solid wire is secondry (around 2kv). the secondry contained one really long winding and then another winding which only went around once (like in a normal mot). It looks like some sort of high current flyback. also, the secondary is also some kind of litz wire. It has many smaller hair thin enameled wires woven into a single strand. My guess it this thing operates at really high frequencies
