God dammit that was beautiful, made me spit out the drink I wish I had right now...
KrazeeCain I WAS LITERALLY CRYING WHEN HE SAID THAT! CLASSIC!!!!!!!!!
This content has helped me understand how wind turbine VFD converter cabinets work and help me troubleshoot them.
The top solder will be paste, the bars needed to stop the paste stencil falling apart.
and when you shut it off it stays running till the caps drain back down,the 1st time on the 220 mill setup l unplugged it but it stayed living, magic l say.
It's because of this channel I got my old Radio Shack multimeter chrome plated. Keep on choochin'
Back in 2000 I started a company where we could HAND solder BGA's. I had so much fun watching the disbelief on engineers faces when I'd tell em, not only can we remove the BGA's by hand, we can reflow them by hand. Of course there is some wizardry involved - but no fancy reflow ovens.
I'm a follower of Mustie1 as well. He makes some nice stuff!
Those notches in the solder are from when the workers hand solder them. They use a technique where they rock the iron left and right as they solder. That is also why you see the through hole components, they get soldered along with the increased capacity traces
Don't know why you need a dummy load when you got two perfectly good hands!
Use google translate on your phone to translate text from pictures, it's not perfect but can usually get you around.
It's interesting that many schematics show an inductor before the capacitor, making a low pass filter. But the 3 phase at 50 to 60 hertz gets rectified into 300-360 hertz ripple, which is still pretty low-frequency. I would only imagine that the inductor would be very large to give the filter such a low cutoff frequency...
Which makes me think that everyone would just use a bridge rectifier and capacitors, without the need for a large, bulky laminated inductor.
I find myself completely lost and mesmerized at the same time watching these vijaoes.
Very current of you to cover IGBT issues.
Aha, they finally arrived! I helped cut the big chunks of plastic at the end. :D
thank you "AVE" for your videos. you are the reason i started in electronics. i also love the way you dumb it down so i can under stand it. AWESOME
God I hope this isn't foreshadowing.
I used to build and wire massive vfd's for pump jacks in north Dakota. Fun stuff!
Glad to see you do a vidjeo on VFD's, ask me for some shop prons of the VFD's we run, home shop running 4. Love yer content AVE
Awesome work mr Canada.
Nice tip on the gator grip socket, cheers!
Love all your vids thanks for the shows ;).....
you need to place those notches on those traces so your reflow solder stencil does not get all floppy on yah and break
it won't affect the current carry capability for it that much as the thinner traces are very short
Thank you for pointing me to the electro boom chanel. I just pissed myself watching that guy shock himself.
I have a feeling those bars/marks on the trace that they coated with extra solder was some sort of tool to keep it relatively even, since solder likes to clump together, you are likely to end up with one fatter section. Splitting it up like this would help it be more even overall, even if some sections are thinner.
Just a theory though.
I didn't know I needed this until now. So happy I subscribed. 👍 my greasy rag & clothes warsher has one to these built in for soft start/stop. Very cool.
Hahaha wicked video! I'm a 3rd year elechicken and I really like the electronics side of things! Thanks for breaking it down!
I bought an inverter mig welder for 200-300$ new. It's chinese, but a guy who serviced industrial welders did the inspection after importing it. Works like a charm.
very informative as usual.
That poor poor iranian lady on ElectricBoom.... ;)
couldn't find it myself, can you post the link?

That board is a Surface Mount Board so the solder is put on with paste and a stencil. The bars on the power trace is stencil support to keep it rigid and not floopy floppy
I'd love to see you tear down a vector drive next.
@AvE They sliced up that soldered over trace like that so if it the trace does fail, it fails there, and not in some random location. (because the soldered over trace may not be uniform the entire length)
Those gator grip sockets are awesome on wingnuts too.
+Michael O and for small hooks!
I used to work in a mold shop that made large container type molds ( think garbage can size) I used to make bearing blocks out of Nylatron. Not a problem to machine except when I did the grease grooves on the bearing surface. Biggest pain in the ass to deburr of almost anything I have worked on. :-) I think I still have a scrapped on in my junk pile somewhere here :-)
lovin your vijeoooosss keep up the good work and thank you
"Put down a bowl of rice and wait for the Iphone fairy to come." 😂
I'd be seriously interested in some of those bgm sample packs. I build a lot of little things that require microcontrollers. I realize those aren't the same thing. With a NAND array containing a bootstrap though, great things are possible. FPGAs and BGMs become seriously useful. I'm familiar with reflow ovens so no issues there.
Ya know what i've been wanting to try...
Since an inverter TIG welder is basically what you have there, i've been wanting to power something off of the leads from my welding machine. Maybe an electrolysis bath that converts the rust in 2 seconds flat. Maybe a thousand LED's...
AvE IS THE MAN
thanks for the vijeao as you say. always learn something here! the solder on that trace must have been applied during the smt placement. those lines are a sign of that. those lines are supports for the stencil. they SHOULD have reflowed the trace by hand after though... but those lines wont be too much of an issue because they are so small.
I had fun setting one of these up for my desktop cnc spindle! It's made better by trying to translate the Chenglish...
you can tell me which part you want read,send me a photo,I will translate for you
patiently waiting
That weirs socket thing, i have one as well. More uses include screwing in hooks amd eye bolts.
Whut? Will that lectrical dohickey start my truck or power my still? Thanks for the video.
When I try to clean my shop, I usually end up making more of a mess...
got to love the Vrrrrrrr mock drill noise. LMAO.
Hahahahahaha! At 5:12 you whistled when you said DC. Ssssassy! Fucking great, truly great. I kneaded that. Love your work, dawwwg.
my 220v outlet in the garage can't handle the dryer we have. in the winter it doesn't trip the breaker as bad as summer I've made sure the dryer is solid and pulling what it should from the outlet, I've also cleaned the thing inside and out to rule out any factors that might come about from clogged pathways for air and heat build up from dusty dirt covered parts, also cleaned all the ground and power contacts. (other factors are at play i.e. shit push button breakers, the longest run in the house to supply the power on 1940's building code wiring). sooooo my question is can I use the VFD to run the motor for the dryers drum and then run the heating element off another outlet on a different breaker.
Such legendary parlance.
Something worth considering is using the Google app on a smart phone. It has a camera fed translation mode that works pretty well between the only two languages I know at least.
Not a complete picture but better than nothing.
That's some bigass nylatron, I just put nylatron bushings in the pedal assembly I modified for my bus, I just put a video up on it too. I'm converting my schoolbus from an automatic to a manual.
"I have fried much more better VFD drives than this..." Purely hilarious and totally candid. Thumbs up.
Holy buckets, haven't seen one of those gator socket things in ages.
I figured those things were just a bunch of bologna as most as seen on TV things are but kind of wanted to try one as every now and then one of those miracle items actually works okay.
Figured if I saw one at a thrift store or garage sale for a buck I'd grab it but so far nothing.
word find has to be one of the handiest things I've discovered. Works on confusers or computers if you will, by pressing CTRL+f to search a web page.
Toshiba inverters are well worth the money - we have some that are over 30 years old and still kicking ass.
Solder has the lines in there from the rollers or conveyor etc that it came out of the machine on. If you look at the other solder on the board you will notice there are more marks similar.
Somebody send this fine man something we can all use, a new camera.
now that I'm drunk I realized something, you are drunk as well. good job haha keep up the good drunk work, your secret is safe with me
in regards to VFDs have you ever come across "capacitor reforming" . in where a drive or other capacitor rich magic box has been left for a number of years , apparently the oxide layer in the caps needs to be reformed through a re-breakin procedure involving reduced voltages in increments and a "baking" wait time .
anaywys love the vigeayos
It will be cool to see what you use that nylatron for. We use it on our atvs to replace the a arms bushings for racing applications. Fascinatingly enough it actually wears out the chromoly tube a arms. I have always wondered why that happens. Could you please explain that in a video about the nylatron?
AvE, I've debated for a while whether or not a capacitor start induction run single phase motor could be run on a VFD drive.
OHHHHHH WOAAAAHHHHHHHYYYYEEEEEEEEEE WOO WOO 8:45 to 8:54 So the thing does power up from the DC!!!!!!!! Not AC!!!! OMG TYG!!!
AvE and you have solved the worlds problem mate!!! I love you bro
I love you like I love like a best friend now because if it wasn't for your help explaining why the device delayed to turn on I can now do what I need!!!
AvE ABSOLUTE MAD LAD/LEGEND!!!!
On the o-scope, was that the 60HZ coming through causing the wave to move up and down as a whole?
Im not sure and dont jump on me if wrong, but i think that those fat traces are there so they increase the Thermal Capacity and they are slotted like that so they have a bigger surface to dissipate the heat
I ONLY WATCH YOUR VIDEOS FOR """FOCUS YOU FUCK"''' WHICH IS EVERY VIDEO LOVE YOUR WORK.
nice , I use those all the time
I agree. When a set number pixies are jammed into a smaller space they get pretty pissed and sometimes see red and start killing each other in rapid succession. Of course, that happens right after they vomit up all their magic, blue smoke.
Don't think my other comments are workin. Love the vids and have watched all of em. Would love to represent with one of your fine shirts!
Those lines in the solder are usually used as a fuse . That's how they can get you to buy a new one and all that's wrong is that solder trace needs to be resolder , I usually resolder those straight from the beginning .
AVE, does you DVM meter need a VFD filter to measure the VFD motors voltage and frequency? why does VFD motors cause noises and interference's?
What about throwing in a similar resistance load of some sort on the third phase connected to a neutral so you can run single phase tools? Or am I just crazy in thinking that might work?
A question for you, AVE. Do you have any idea how to build an induction heater that could be used to heat steel, and, if so, could you do a video for it?
400 HZ is what is used in aircraft. Yeah I'm subbed. Good video.
Inverter? I hardly know her!
lol
+Granite Let's do a three phase. You inverter from the front and I'll rectifier from the rear. Zak can run the camera.
***** No, once you get to three or more phases I'm out. Not even doing the camera.
+A. Zak Wise decision. Any more than three and there's elbows flying everywhere.
@@robertbrowne7880 three holes noone needs resisting
followed for the type of content you release, stayed for the jokes.
I'm thinking the funky land pattern is created to be a "Shunt". A shunt is a low resistance path used to measure voltage drop which then can be translated into current. Perhaps used to monitor VFD current for overload protection.
With the chop saw, why not just use a heavy (or bank of) diode to half wave the AC before the brush motor? That will give you half speed.
11:28 I had to look up what that word meant and I laughed my ass off. Hahaha
"That hirsute lady on the Electroboom channel"... But that's the way Medhi likes it, uhn huh uhn huh, that's the way he likes it.
+MattsAwesomeStuff Heh, total roast or what?
I have a three phase VFD lying around in my garage. Looking at that circuit diagram, could I use it to convert single phase 240v (US residential power) to three phase 240V???
AvE You did a video on compressor using a VDF. Can you go into the correct sizing of the VFD? Also the motor on mine is so old that the FLA is not listed on the plate. .What to do, What to do? Thanks
Is it possible to chop apart a inverter to turn what would normally be a DC welder in a HF - AC for tig welding aluminum?
Always dealt with the annoying stuff, never heard it called Silastic glue... never really heard it called anything before though. What's the advantage of this stuff? I usually see it quieting and supporting through hole caps. If I pop some RTV on there am I getting the same thing albeit slightly more flexible?
Are you sure the scope is floating? PE and N are basically the same wire (the only difference being that PE can not be cut by a breaker), does disconnecting PE really help?
"The cheapest marettes that Chen Sen, can manufacture. If you think about it, just about everything we buy is that." I immediately thought of, Peter Stomare's line from "Armageddon", "Russian parts, American parts, ALL MADE IN TAIWAN!". Scariest part is that kids, who were born the year, that move came out, are now/soon to be, of legal drinking age (21) in the US. Feel old? I do.
Speaking of inverters, I would love to do a teardown (and rebuild) of my Exide 2000ex 2000watt (more like 3500watt) inverter. It is a 12v to 120v modified sinewave inverter/charger and I swear they built EVERYTHING on it WAYY over spec. I just can't find any documentation on it anywhere -.-
Why do the pixies blow blue smoke when they get angry?
+AvE haha
would love to see you go through a welder and compare cheapo welders using MOSFETs to igbt welders and compare the how skoocum Miller is vs lincoln
I love inverter s. Great toy!
And what exactly were you trying to do? You can 1ph off a VFD a motor on a saw to get it to cut metal? Pretty sure output phase loss is under the list of faults that get ignored when I ignore all on those Altivars I have kicking around the shop. Hmmm....
"Link in the dooblidoo"
So is AvE IS a nerdfighter !
+Derek Richline Probably both
I was asked this and wasn't sure on the answer. Th question is: if you ran an electromagnet with a VFD dose the field strength increase or decrease as you change the hertz?
That transformer joke got me good
You need to be careful using a oscilloscope on mains power and not using an isolation transformer or by just removing the ground pin. In most, if not all, common electrical systems the neutral is connected to the ground bus in the breaker panel. So you can still dead short an oscilloscope if you put the probe ground on hot.
I barely understood anything about this whatchamacallit box, but god dammit you could be reading a phone book and I'd listen and be entertained.
Regarding the slots in the extra solder on the high-current traces. The solder paste is scraped out on the PCB with a sharp "rake" through a thin, laser cut stencil. All large openings in the stencils need to have "spokes" to prevent the rake from getting caught on the edge as this would f*ck up the stencil.
And the negative effect of those slots is roughly proportional to the percentage of spoke vs. trace length. Say 5%.
+AvE The schematic you showed at the beginning was a 3 phase, not single phase. Hertz (or frequency) has no effect on voltage as you referenced. 10Hz and 400Hz at 110v provides the same amount of EMF the difference is the number of transitions from + to - power second. Do you make this shit up as you go along?
+Rich Booth You need to lower the voltage together with frequency, otherwise decreased back emf in motor would cause too much current to flow.
Sufferin Succatash!!! Do you need any more meters to analyze that power inverter, gizmo, AC/DC thingamajig? Remind me to never let you lose in the cockpit of a B-777.
i got one of those gator sockets as a last resort, because i come across a lot of stripped bolts, and have boogered a few myself,
So if you can get a single phase out VFD, would it work to slow down a bench grinder? I've been looking at one from Eaton. Thanks
I think the term you were looking for was thermister for the hot checker on the heatsink.
