Scariche elettriche prodotte da un MOT
MOT / Microwave Oven Transformer Rewound for Use with Chlorate Cell. A Center Tapped Secondary and Alternator Diodes are Used to Further Reduce Cost. Diodes are 70 Amp. If a Higher Voltage is Desired, Several More Turns Can be Easily Added. Microwave Oven Transformers can be Removed From Ovens Found out for Trash….Like the one I am Using.
@nebius86 more like 4K lol
It’s about 2KV with 0,5 ampere! Attention, this current is lethal!!!
nice, i’ve been wanting to try this myself. how many Volts is it?
Können Sie ein Video von Ihrer Aufstellung machen? Identifizierung sehen mag es!
oh okay, that makes sense…thank you!
If you are referring to the third terminal on the primary, it is an off center tap for the high power setting. The microwave that I removed the MOT from had two power levels.
Nice video on a rewound mot for power supply! But i was wondering… What is that third termnal on your mot for? I have nevrr exipienced a third terminal on any of my mots lol
I am using two 22,000uF at 75 volts on the first side of the inductor and one 80,000uF at 25 volts on the output side of the inductor. The inductor is a swing choke that I rewound with 10gauge wire to handle the current. It originally was wound with 14gauge. I have not measured the inductance, but I did scope the output and adjusted the caps for a 1/10 volt ripple at running current.
Thank you! Last question, a friend said to use 2200 uF 25V capacitors, is that correct? and the inductor what value should i use? thanks!!
I didn’t show that in this video, however, you can filter with capacitors. Best with an inductor in pi filter configuration. The alternator diodes in the case have more than sufficient voltage handling capabilities and are not a concern. The diodes should handle plenty of current at the voltage you need but they will need cooling with a fan.
The diodes, need to be 12V or 5V in the case, or it can be 100V~200V? with 70A? sorry for all this simply questions…but i really don’t know…
Hi,
I was talking to someone who understand electronics.. then he said after the current comes out of the transfomer it needed to be rectify,filtrate and stabilize.. do you do that in your movie? how should i do that, with minimum cost?
ThankYou!
Your work on the furnace is very good too.
exellent! very simple, cheap and very special construction.
I knew that i had seen it before… thanks
Thanks,The ampere and volt meters are pictured in the video. It is not a motor, It is an alternator off of a car. I loaded the output between 20 -32 amps.
Hi
How many ampere does thins give out?
Where did you get the electric motor from?
Thanks, great video
Thanks, 80927269.
How are you calculating / measuring performance or efficiency?
Hi I wanted to share my results with respect to efficiency and performance I probe with dichromate and sodium fluoride to increase the current in the cell to maintain a pH between 6 and 6.5, significantly improves performance by 15% or 20% but increases the level contaminant, another factor is the temperature since this affects the decomposition of hypochlorite to chlorate and must maintain a minimum at 60 ° C, these are my results in my tests, I hope can help..
that sounds good, thanks for letting me know
Yes, that’s right. I just didn’t show it. I usually run a cap that is 20-50,000Mfd. For example; On my cell that runs 6-7 volts output from diodes, I use 75 volt cap at 22,000Mfd. It is a little bit bigger than a beer can.
Approximately .7g of chloride is converted to 1.5g of chlorate per hour at 2 amps at 100% efficiency. So lets say it will take an hour and a half because of inefficiency. To convert KCL03 to KCL04 takes 5Ah per 10 grams. So, for 500g of chlorate it should take about 250Ah to convert at 100% efficiency. A little better than 15 hours per lb. at 20 amps.
I usually don’t calculate very close. I just run as if I’m at 40-50 efficiency and it seems to work just fine.
Nice video, it will be quite helpful to me for my experiments. Would you know approximately how much time it would take to fully convert chloride into chlorate? Then, how much longer would it take to get converted to perchlorate?
Just a thing, didnt this circuit need a capacitor in order to smoother current to cells? Or will this not be very important?
Thanks for this video!
Problems with power supply no more! High reability high amperage low voltage PS from scratch! Like also the idea of using alternator diodes…I think that should be little more difficult to obtain thought..I will buy a 50 amp diode bridge instead..
Thanks ytmachx!
Exaclty. When I was doing KClO4 cells, I used Platinum as well, but you know what? It does corrode, just very slowly. I got fed up with buying Pt electrodes. However, your electrodes seem to have Niobium in them. Where were you able to find them? Currently (on and off as well), I am researching on MMO electrodes.
Thanks cobra!
I am going to agree with you on this, a new, cheaper material for anodes would most definitely simplify the process. I am using the relatively expensive Platinum clad Niobium. It appears to be impervious to the strongly oxidizing chlorate solution.
ytmachx, your videos will never cease to amaze and interest every cell in my brain. I would like to, however, comment on how my problem isn’t the power supply, but rather the materials used for the electrodes. I believe you would cause a revolution if you were to develop a great MMO electrode from scratch, or something similar. I look forward to your next video!
Thanks,80927269 Yes, it is possible to make more chlorate with more current but the electrodes have to be able to handle the level power.
I make 1200g of chlorate in 6 days running 22amps at 5.8 volts. Watch my other videos.
