youpattube1: thanks for the instructional vid. but there are a few places that i could
not understand . if you wanted 18v on the secondary, why did you double the
wires, and then use the full number of turns ? your result was (using the
center tap) two 18v outputs. what did you gain by doing that ? also, when
you were checking for continuity amongst the 4 initial secondary wire lead
ends, the video didn't seem to synch up with the multimeter explanation. i
couldn't figure out what was supposed to
GoogleMinusSucks: The chart doesn't go have what i want to do...I want to make a transformer
that turns 120V to 12V and i want to get 75 amps at 12V...how many turns
and what gauge wire (AWG?)
cyrusrom: I meant if I were to go to a shop where would I find it? But nice video
Xuesong Qu: great video.
simontay1984: Where are you from, it is very difficult to understand you.
James McClain: Can I use single layer magnet wire
SolarGridUk: What was the 42 number was that a voltage required or what
elektroxi: thanks :))))
Noscrubjections: superb video!
qOvob: i like his accent he's like my programming teacher haha
Asmit Naik: how to find constant ?? u mentioned 42 how to get it ??
Steve Marshall: I am looking for the templates for the form construction for transformer
RJMBudz: 1 question pls...the 100 rounds of magnetic wire how many volts? thank you
professorfidelcat: vive Colombia nice video on electronics!!
RiouInsuiko: Really well done, very informative and a nice professional presentation. If
I ever have to make my own transformer.. this video will be my go-to guide!
DJSmileysLVBD: you should make an English version of your website, it would make things
much easier. Great video thou :)
PetruV .: you make everithing seem so simple
Viryl Lucas: _ espanol
Baiju Indulal: Usefull vedio tips for beginers
MattsAwesomeStuff: Great video. If anyone wants to know how to make big transformers for free,
or see an idiot-proof method of calculating the important stuff, with
almost no tools, check out my channel. I've made a tutorial series showing
how. It covers similar content in this video in a different way. My voice
is sadly nowhere near as exotic-sounding though :P
Atif Ali: Thanks A Lot Sir
ranjank91: How can i calculate core area of 3 phase big transformer. If core former is
circular we can find out radius using core area. If core former is
rectangular how can we find out length and breadth of former using core
Dharma Kissoon: how can i test for amps
asmvax: From what i know, is outlet frequency/surface. In what country is 42Hz on
Visar Alexander Pitushi: Very professional !! Excellent... It's better to do it yourself than to buy
احمد البيومي: great video, what about wires diameter ?
Bey0ndReach: Yes, that's correct. 40-42 is risky, especially when using the transformer
to it's fullest potential. Using 45-50 spins/volt insures that the
transformer doesn't overheat, and you can let it in the power socket
indefinitely without worries. I use more detailed calculations than shown
in the video and i always end up with perfect transforming ratios and
output voltage. The last one i built was a 18V/2,5A for a 40w home made
stereo amplifier. It doesn't even feel warm while running.
Lee Song: Sorry, i got my answer from google. So may i connect the central TAP to
first 18v, second 18v and ground together? thank you
ilzul12: nice video, keep it going!
William Sledge: Thank you, great video, nicely done!
Jeffrey Alden Olson: do you really need to connect the butt end of one secondary to the front
end of the other secondary? couldn't you just tapp the middle as it was
TuliTech: No, transformers can only be used using AC. There has to be a change in
electromagnetic flux for a transformer to work.
Arun Saitawadekar: have you practical of table/ceiling fan winding video ? or where do I
search practical of table/ceiling fan winding video ? Please tell me.
naeem Khan: you are great and respectable
Ayoub Ali: thanks u alot
Sir Spf: This is one of the best transformer instructable videos I have watched so
far. You explain the basics how a transformer works, build one from scratch
and even test it out! One question though, what is the diameter of the
copper wire of each circuit? Usually it differs from the primary and
secondary coil according to some websites.
Gianmaria Draghi: hello How do I make the iron E parts?
Brandon Jackson: Where can I get these silicon iron plates? Preferably somewhere where I
don't have to order a minimum of 1 ton. BTW I'm in the U.S. so possibly
some place here where I dont have to wait more than a week. Tried amazon,
tried google. No luck. Unless there is a different search query I should be
using other than "silicon iron plate?"
Andre Gopee: How do you calculate the constant? Andre
Rebecca Morrow: where can i get t5he material for this? I am going to make this foor my
Yumi Auroris: what is the purpos of the silicone iron plates?
VisulX Production: how much is this transformer?
tino tino: I also want to know about wire diameter (thickness, gauge). I see in
secondary, you use thicker wire.
Ahmed khalil: how many winding do i need for a transformer transforming from 12v to 3.5v
Gianmaria Draghi: Hello This site 'tecloradio' does not work. Can you rewrite it, please?
Bey0ndReach: Even if you don't connect a consumer to both windings, a current will still
flow in both of them. So, there is no wasted space.
Bey0ndReach: Oh, damn, sorry, i wasn't paying full attention. Yes, it's 42 for 60hz. In
my state the standard is 50hz so we calculate 50/S. For 60hz, 42/S is good.
For my transformers i even use 45/S if they are bigger than 5cm^2, in order
to save wire and still not getting warm during usage. (if they are welded
tight and properly). This means that you can use 37/S. The equations for
the wire thickness are the same. Sorry, again, if i misled you. If you want
to discuss more about this, PM me.
cyrusrom: where would I find a formwork if I were to go to a shop?
Shagas Heizenberg: wow so many stupid people...... questions like "why buy one when you can
make one" And comments like "annoying accent" . Really shows the ignorance
of the current generation Thx for the video
