2021 I bet you didn’t think you would be where you are now Love the videos Also hello to others here around 2021

As I am currently watching my wife and both cats are intently viewing and taking notes. AND she knows what a VFD is.

GOODNESS, here I clicked through thinking this was some new-fangled content; wound up going for one hell of a nostalgia trip. And it's only been 8 years watching this channel before I finally figured out what-the-fuck AvE actually *means!* I'm a goddamned genius.

Heya, another girl that finds your vids and sense of humour entertaining. I also often find myself watching big Clive's channel. We are out there;-)

I work on VSDs (Variable Speed as apposed to Variable Frequency) daily. Just had an electrician hook up one of my drives backwards last week. 480V Shorted the IGBTs and Cross-phased. We were standing in front of the cabinet and the door must have mushroomed out 6 inches. Oops, that's a $15000 mistake. Usually I double check everything but he assured me everything was good to chooch...

"Keep you stick on the ice" I legend was born.

I'm watching these! >__> Teardown videos are sorta relaxing :)

I am i love teardowns! I got a degree in Electronic Engineering

"Keep your stick on the ice." This must be an old one.

I love how you baited the women to speak up!

Came to the comments to see how many women popped in to correct AvE haha. Glad to see the field is more diverse then it appears to be sometimes :D

I'm watching it !

Just another girl watching your drive teardown! Love controls, automation, good old ladder logic and always love watching your videos. #JustAGirlandHerTools

Oh, this has been a long time. Feels like AvE being in my life since forever. Gotta stop thinking otherwise it will trigger some nostalgia crisis xD

My girlfriend always comments when she hears you introduce your videos with "welcome back gentlemen".

I am a woman and I am watching this tear down! EE FTW

great stuff, thanks! I want to design my own VFD, so I'm looking for everything related I can find, this was pretty usefull

Hey AvE, Not sure if it's your hurt pride or some other issue but you freaking Rock my friend . It just shows that your human and thats awesome Wishing you and your family well and a Merry Christmas/ Happy Hanukkah . Keep choochin man !

Only youtuber i have found wise enough to take his dumb moves and post them publicly so we may all learn..

Hey! im a woman watching this teardown..ive got a dead 7.5 KW inverter i need to sort out :P

Ur a use’n your electrician voice, quite lovely

Man, you would love getting into Battle Bots. The hands on mechanics and the electrical aspect, the hydraulic / pneumatic stuff. You could flex all your muscles.

my wife watches your channel with me all the time

I know a guy who forgot to install the 120v adapter board for the 24vdc inputs on a magnetek drive. It was for an old crane with a 120v control circuit. His drive blew up in quite the same way and the funniest thing about it is he has been working with drives for 30 years as an electrician in a factory. It happens to the best of us! I’ve never wired the load lugs on a drive backwards but I know a few guys who have. They all had similar results 🤣 A wise man once told me, “If you aren’t fucking shit up, you aren’t fixing shit.” 🤷‍♂️

Hmmm, interesting... I run my Harrison M300 off a Mitsubishi VFD and mounted up the optional PU under the DRO. Makes varying the output frequency really easy. The lathe has gearing to spin up to 2500 rpm so I never really have to overclock the motor but being able to slow things right down for blind internal screw cutting is uber cool. In all fairness it does say on the first page of the Manuel not to let the angry pixies anywhere near chooching up the output 😁 Yep, I cheated and read the manual, these VFDs are just amazing little things. I still run the Bridgeport off a rotary phase converter I built myself as there are issues with the contactors running off 110v which I don't have time to sort out.

Where did you pirate your version of DaveCAD? I've been looking for one for a while now!

This happened on a job i was commissioning recently. The electricians landed the high voltage to the motor leads on a the vfd for a 40hp 480/60/3 motor. When that one blew... it was loud! Sounded like a gun went off. No bueno...

Wow I totally need to meet those hard to find techie engineering girls here on your channel!

Fascinating 👍🏻

KZfaq recommending me those 2013 gems.... Nice?!

9:16 Prelude to the legend...

11/12/21 the day a 8 year old AvE vid randomly pops up in my home feed. Someone has been slipping the algorithms some Canukastan Kopecs

My wife is watching this with me :P

This is the best part about letting the magic smoke out you get to tear it apart and see what you did even better yet you get to see if you can make it work again 🤔😁

Best regoo ever.

I run a Boxford Model A underdrive.... nice machine...

I like the 2.0 Ave

You let the smoke out!

Hey AvE, not your usual jovial self, everyone blows thing up now & again. : )

Did anyone else just get this as a new video?

Worth painting the DO NOT CONNECT BACKWARDS connections very red. If not now, then for the future.

Professionally drawn in DaveCAD :) You missed out on that :) it is important!!

it sucky sucks to learn the hard way, but at least you learned something useful. "if you hook up electronical gizmos backwards, you're gonna have an expensively bad time". i believe i already knew that, but don't ask me how i know. it's far too depressing to think about.

I could find the full explanatory blog link .. can you please post it on the link ??

Wobbly pops!!! They make the angry pixies smoke.

This is the first real Ave video.

Came up on my feed as a new vid LOL ANNNNNY WAY - I always say - always take it apart, you can throw 5 pieces away just as easily as 1 and you might learn something and maybe even fix it!

Oh that was great.

I usually leave KZfaq on autoplay when I'm on any subject I'm interested in and I was watching some of your videos so i was on your playlist and was about to turn off the PC to go out when one of my girlfriends told me to wait because she was interested in this video after watching two or three of the ones before it. We made it about 30 seconds into the video and she called you a "narrow minded ass" and walked out of the room after hitting my computer screen with the chip she was working on, from her work station across the other end of the room. I thought it was funny, so... I'm hitting "subscribe" so i can turn on your videos when i want the lab to myself ! Can you guess what set her off? LOL

Omg how AvE style changed! I missed the gentlemaaaaaaan

damn i would love those heat sinks XD

the other video is gone, where did it go....i was looking for the one you had pulled apart that was hooked to your rock crusher

Uncle Bumble had not yet been born.

I recently learned that the JCI series 2 VFD which is EATON H-MAX series will take AC 3 phase into its output and live with it (I am sure if it was trying to output power that would not have been the case)

Flyback diodes blew. Just too small to handle the inrush current to the capacitors at startup. If you put some current limiting resistors in series you could actually get the drive to power up from the output power. In fact, when you are decelerating a load the current that flows back and causes the DC bus to rise flows through those flyback diodes. There were a bunch of assumptions that led to me powering up a 1200A VFD from the output stage. For this particular lesson we were lucky enough to have only a 300A breaker on the front end. That saved our bacon. We did have to wrastle new 350MCM cables for both the input and output stages to fix that fuck up.

Know what? Ya got one of those six-way diodios in your old truck's alternator!

Hey there can you please please do a full video on repairing single phase to 3 phase vfd repairing???

Spark fun sticker!

Second trip to harbor freight still terrifying

Automation Direct has some inexpensive and sophisticated toys if ya dig PLC's and 4-20 control stuff.

hahhaah all the women come out from the woodwork

If you want to see smoke & a extra loud noise energize a 125 HP VFD. I replaced a bad IGBT in what Danfoss tech called a 6 pak without replacing bad small control board. I moved ramp up time to 60 seconds. When it got to 10 Hertz IGBT blow up. Thought I was back in Nam with the extra loud noise. Was told that all drives 5HP & under are now considered throw aways. Does anybody repair boards on larger drives anymore? Throw away large boards from 60 to 125 HP because drive company does not repair them.

at least you did it good.

Finally.. something I can use. Lol jk I’m Constantly taking something apart trying to figure out why it blew up. (Nothing I did it, just blew up on its own “ wobbly pops” or not .) Ok MAYBE I have a vfd for my drill press But I’m just maybe a little gunshy. I’m taking lessons thanks bud! Looks Like the same one.

At first I thought Vacuum Florescent Display. Nah, this is AvE.

👍

The company I work for built the automation direct headquarters here in Georgia. The guy that owns it is said to be generous. maybe he’d sponsor you.

funny my gf was watching this vid not too long ago, shes a shop dork as well

female here lol watching

Got tricked by the Algo again, showing me a 10y old video, lol.

Just came here to see the comments of the 10 or so women on the planet that are actually watching this

A very young sounding AvE

Look at them young hands!😂

Is Practical Machinist still good?

which blog? that empty one?

I am not above asking my helper to verify my wiring before power up. It has saved me more than a few times. Everyone screws up occasionally.

You let out the snoke! Small little vfd. Fractional or 1 horse? Not very many people seem to understand how a vfd works. I work on them quite often as i am a pumping equipment technician and 3 phase motors and 3 phase submersible motors are very common. I typically get my hands on 7.5hp to 200hp vfds

This be a yee ole Mr beater flick

Did that once. Let all the magic smoke out of a $6000 VFD. Vice President and I had a sit and chat about that one. Haint done it but the once.

What was the goo in there for?

one flied riode :)

that goo is non-conductive?

Schneider ATV312 will amazingly not blow up, and will actually pop the screen with a helpful fault when you do this. My field techs are often stupid.

Why the heck wouldnt they put a fuse on the power board ?

4:30 "..Need to find your DC bus in order to troubleshoot your input.." looks at both sides, flips to other side "to troubleshoot your inputs, and to troubleshoot your outputs." I think we know where you went wrong last time

In the several videos I've heard you casually mention the price of the microscope, it just keeps getting cheaper and cheaper lol First it was like 100 and then 99 and then 75 and now 30. Pretty soon, I feel like I'm gonna watch something where you say they paid you to use it!

Ahem, I am watching, but hope I never have to repair any of my 4 VFD's. BTW, even my Huang Yang VFD's warn against that very thing! Kate

Yes theres a girl watching this.....we do exist.

O.G. BOLTR.

My Da and brothers always called me "a big gurl" so there is always a gurl watching

the only comments are from women's vitriolic reaction to his assertion that there are no ladies here. I wanted to comment: thanks for the good laugh man, your channel never fails to amuse

Good grief you sound so innocent here.

Hooked it up backwards? Sometimes you just have to forgive yourself for being Canadian! Hah hah! Just kidding, jus kiddin'! "The magic blue smoke monster", hah hah, this guy is funnier than sht!

Unless exceeding the rating of the cap it wouldn't blow because of ac or dc. AC passes through a cap with a phase shift and dc is blocked.

woman here and watching and in Seattle lol

Could always be worse... it could have been four drives.. say around 22kW with Schaffner output filters... the Pixies don't take any prisoners with them running backwards either..

AvE sounds almost a decade younger here

“Barse acwoods “ Nooooooooo. 😭

00:20-00:26- AvE is Hydra - confirmed.

Well at least one Wifee watches your vids, and she doesn't shop at IKea so no hotdogs for me........
