DC-AC inverters need more voltage in the DC bus due to the rated AC voltage being measured as RMS and the DC being max, such as a Bosch-Rexroth, FANUC or Siemodrive servo control system. I would ask the engineering department to explain better but they keep avoiding me.
Not necessarily if you are using a VFD. An example you see every day arehybrid cars like a Prius., The 201vdc battery is fed to an under-hood "VFD" (inverter/converter) which provides a dc/dc boost conversion (converter) to about 500vdc and then inverts the higher dc voltage to a maximum of 650vac three phase. Which creates a variable frequency drive to control their three phase electric motor system. It's also a dynamically reversible process which can instantly turn the mechanical energy back from ac to dc and charge the 201 battery.
More AvE and Dewclaw duo please! You guys are so funny! It reminds me of a mechanical engineer friend and I. We work together and when we are building stuff we are always cracking up like you guys. We hypothesize and test our theories. We make fun of each others areas of expertise, mechanical his and electrical mine. We always have a great time working together and is the same vibe I feel is between you two.
Contactor not rated for DC loads? No problem, let's add a gigantic inductor! Great idea, if it doesn't limit the inrush, at least it'll turn the contactor into a stick welder. Was that thing supposed to open ever again?
Reminded me of my days testing UPS battery banks, the M.O. (modus operandi) was to not use both hands when testing so as to avoid at all costs any chance of completing a circuit between your 2 hands and (if you're lucky) a trip to see the EMS folks. It of course doesn't help that working with lethal voltages causes ones heart to race and hands to sweat which increases conductivity. I learned early on as an apprentice sparky that you treat every wire as live and lethal, so that when you do come face to face with a real live one, you have trained your psyche that it's not any different than any other situation you've done 1000's of times before.
Must not have been all that wise. You'd lose your job saying it like that. You need it to be more like, "The precise correlation between demonstration and theory has yet to be ascertained."
"Nerdly" fault. I was breaking my head over this until I saw it said NRDY, otherwise known as a "Not Ready" status.... Ah, VFD's have such good problem indicators.
Here I thought it was a bigger version of the other Hitachi tear-down for when the better three-quarters really needs a serious 3-phase foot massage to bring down the heavens.
Ol' Dewclaw has that Hunter S.Thompson mumble going, I can only Imagine it gets more pronounced(seems the wrong word to describe a mumble) with more beers.
Tips: If you want to break hi voltage DC with a motor contactor, run them thru all three phases of the contactor in serial so you will have a better break gap, not just one.
The Claw is back , long live the claw! You keep putting your pinkies close to that 236 Dc while looking thru the camera and one of these days you gonna be first Canuckistany to fly by electrocity. This is a great thing for those people who live on batterias. I can't wait to see the next installment.
I'm supposed to be working on something that makes money yet I am here. Why am I here? I don't know, but I thoroughly enjoyed this video despite the fact that I will never use any of this information because I will never ever run my air compressor in this manner. I will hook up a windmill or enslave rats to my air compressor before I'll do this nonsense, yet I watch the whole video for absolutely no reason and I'm not sorry I would do it again.
..... Dewclaw shows up as froggy too? Mobile air and battery pack? Mods to fork lift? 4Kw solar? Air rams/pumps? Vertical wind turbine? All to farm cranberries.....
I hate it when you have a perfectly set up gag and someone drops the ball. Lay off the devils lettuce dewclaw....or maybe try more? Yeah more is always better!

And I will watch many many more of your videos till i get it. Because what i understood for sure is : You know your stuff.
Friging amazing what can be accomplished when funding is not an issue, (need more batteries, no problem), and intoxication removes inhibition. Then… creativity, and intuition is free… to break though the boundaries of innovation! I am, impressed!
I run my 12000lb vintage metal lathe with a similar setup, except it's 50 truck batteries and a 30hp VFD. This is reminiscent of all the messing around I had to do to get mine to work.
Hahaha - Dewclaw and I have the same pliers and I use them for the same reasons "Doing a lot of things you probably shouldn't do" Haha! Awesome Dewclaw!
Oh you almost got me. I was about to ask "what, no epilogue?" Ah, but there it was. Awesome stuff man, you have given me a few dastardly ideas with this one...
Having had some idea of what you were trying to accomplish, this was a very entertaining vijayoh. For them what hasn't had proper apprenticical training, electrizmic components are small containers that have a measured amount of majikal pixie dust called spec. When a component fails, generally breaching this small housing and releasing the contents (often in a puff of fire or greasy smoke), the component is said to be out of spec.
380vdc, just about perfect to run off of the battery pack on most electric vehicles! Gotta be real careful with that hvdc stuff, it'll fry you right quick... I work with the high voltage components on EV's on an almost daily basis. Just today I did an "experimenalt" swap of a Toyota Rav4 EV battery pack with one from another car. If you are looking for a contactor (relay) for switching that kind of voltage, I'd look into getting something off of some EV or another. We use Gigavac contactors on the DC fast charging kits we build at work. I think they're rated for 1000vdc up to 500a, and are powered with a 12v coil that draws about 0.3a. Some EVs use contactors powered by PWM though, so something to keep in mind if you grab something used...
I have spent many hours in front of some god forsaken drive I've never seen before disparately googling manuals. I can absolutely relate to this video!
Had bolted 600v infeed to the building I work in loosen over the years of heavy service, every once in a while the whole shop (40" 7 unit printing press, multiple big ass compressors among a ton of other equipment) would get a momentary power cut when it would work its way to a near open, then immediately come back up. We spent weeks trying to figure out where this bullshit was coming from until I happened to be by the electrical wall looking up when it happened. I hope I never seen 4/0 wire coil up and leap like a snake ever again
You bring back great memories of when the latest generation of equipment shipped and was delivered to a job site with no formal training. Good thing it was a great paying job with Union benefits....Our sales brochures said....Factory Trained.....More like "Hit n Miss" in the field! One question....from a casual observer....you were lighting up the VFD drive computer with 120VAC it seemed....Guess there is a further workaround with Auxiliary 12VDC to 120VAC inverter....Time to run back to Princess Auto I think👌
always good for a laugh and education. We use Mitsu. drives in the control panels we build at my job so its interesting to see another drive manufacturer unit.
I got one of those DP712s a couple years ago. Of course I fried it with some lead acid batteries, and they fixed it under warranty. It's been awesome since.
As someone interested in both off-the-grid stuff and stuff with 3-phase motors, and largely having resigned myself to the belief that ne'er the twain shall meet, this is the kind of science I need in my life.
About the only reason nowadays to have access to the DC bus on big drives is so that multiple smaller drives can be hooked up to a common DC bus to share braking power. They will usually have one big-ass rectifier to run everything.
Some folks would look at all those batteries and work, and they might ask 'but why would you do that'? Because they could! One of the best reasons for doing anything, for the hell of it.
Hey we use those same AB contactors for running are CAT 3 motor power . Run power in through 1 and back out the other to the motors. Aslo run the reset for the estops through the snap on auxiliary contacts sometimes will use a sick safety relay for that too. Anyway kool vid.
I think DMG Mori had something like this in store but they dropped that shit years ago, that's what happens when you sell to much stock to the Chinese...
"It's not a fault, it's a feature" - that, sir, is gold and I'm going to use it whenever one of my d.i.y malfunctions has unforeseen fortuitous consequences! ;-j
great video looking forward to more from you guys as you up the sketchiness of the equation, after all that is one massive TIG welding setup you have there, no wonder the contacts fused together, come on break out some argon and a tig torch....
I once connected 150 slightly used 9v batteries in series and it would arc half a foot and make the hairs on your arm stand up when you would get close to the under insulated wires
I knew a guy that was poking around inside a piece if malfunctioning equipment at the print shop he worked in as a maintenance/repair guy. He was using s pencil to push a cluster of wires aside a bit to get a look at something underneath when there was a flash, a fizzpop and shower of sparks. The tip of the pencil, if course made of conductive graphite, had contacted and shorted something live. He was unharmed though his pants may not have been so lucky. When he did his standard firm write up on the job and incident he said "While investigating the malfunction with an INSULATED GRAPHITE PROBE....." He was never questioned on it, despite the "probing" necessitating replacement if a costly control assembly

Square root of 2 multiplied whit the efective voltage on AC gives you the peak ac voltage
