Omron/Yaskawa 3 kW AC Servo Drive Teardown - Isolation, Day 34

- I scavenged a old 4 ton stone polisher machine for the best components and got off with a 3 kW AC server motor + drive, 4+0.55 kW variable frequency drives. In this video I teardown the servo drive that let the smoke out in the previous video.

Its eaaaaasily repairable , totally worth the effort to repair
If it is old or common enough, I will often prioritize a teardown higher than a repair. It is simple time available management, lots of components, very little time.
We use thees drives in the equipment we build at work. Nice to see a teardown..
Interesting construction on the brick. I also expected it to be filled with this clear gel stuff that is in most of them.
Just for the fun of it, I have tried to melt this gel to even it back out after poking around, not even with a heat gun at 2 kW at full blast will it soften up or melt. It is truly made to contain a lot of energy.
Please give your wahttsapp or viber Viber
The IGBT????
I like that stick….do not trash required equipmens.
Anytime I trash and looking for later😅
I see that the magic smoke has been released here.
It was only the very little magic smoke, the big one stayed in :)
Can we expect tear-down of servo motor? Interesting to see rotor construction and magnets position.
Sine you request it, it shall be done.
@@KaizerPowerElectronicsDk Maybe my comment sounds rude but that is due to language differences between Macedonian and English, not intentionally. Greetings from Macedonia.
It just went online!
@KP I rather do a teardown than wait for the 1 in a million buyer on ebay :)
Brilliant .... You look like a Danish King :)
Please do a close up of that igbt brick
36 hours.
Cool, endelig en dansk elektronik nørd kanal....👍
Du har været lang tid om at finde den :)
Hallo, is there any disassembly manual for cimr-v7az21p5
Sir from where to learn this servo drive repair .
Pls reply
Hello Sir I have a drive of LG FDA 5000. There are some errors coming in that I do not understand, can you help me?
Hi Vijay. Maybe, what kind of errors are you getting?

Cool
We need close up shots
I suspect that if you just unsoldered the serial driver IC, the rest of th drive would probably work fine??
ТО есть вы не стали разбирать блок перед прошлым пуском, что бы проверить и очистить от грязи, подали питание на него и сожгли?
I wonder if there is an IP65 or IP67 version of these drives...
Nice one, please do more lengthy videos.
It is in the plans as mentioned :)
wow, the state of that unit... people really need to be placing these drives (including vfds that are not Nema 4+) into dust- and water-tight enclosures. i've watched a million of these drive repair vids and almost all of them have one thing in common, the boards are completely trashed with layers of filth. i'm no engineer by any stretch of the imagination, but it seems silly to me to install high power/high voltage motor controls without any degree of protection against contaminant ingress. it's especially bad with HVAC installations, with no shielding against condensation, and very poor heat-removal methods. and then users wonder why their drives become unreliable, blaming their failure on the igbts or the manufacturers/repair techs 🙄 i wonder how long it's gonna take before installation technicians figure out that drives need to be protected if they aren't already rated Nema 4 and above.
at that point i don't even consider it to be a lack of understanding of what drives are or how they work. you'd think that if you're hooking up a 3kw motor to some component, you'd logically infer that the component is handling a serious current and voltage load, and that you should put it in a damn box. that would be like utility companies installing transformers on poles with no tank, oil, or bushings, then crying about unreliability when they go bang after two days. sounds dumb, but that is exactly what's going on with the shoddy installation of drives like this.
sorry for the rant, but i really hate to see semiconductor-based drives get a bad rap from failure caused by meat-fisted and smooth-brained installation personnel. this type of technology is at the cutting edge of energy conservation and the switch to electrification, and drives should be treated as extremely valuable commodities. these drives are gonna be made smaller and smaller with increasing efficiency, and will find their way into more and more consumer appliances, especially with recent advances in SiC-based switching. they already are everywhere as it is. you wouldn't store crude oil in tupperware, so drives should also be kept safe and secure.
I have seen it in so many factories. Dirty control cabinets. Usually due to maintenance costs on changing filters have been cut! In more modern times, refrigerator cooled and sealed cabinets was used in the brewery business.
@@KaizerPowerElectronicsDk yep, it's silly. they cut maintenance costs, and next thing you know the VFD goes pop. and there you go, instant downtime, with an expensive repair, likely a full unit replacement. definitely more expensive than just cleaning the vent filters 😂 and yes, i actually work in a modern brewery, and the multiple vfds they have are all either in sealed control cabinets, or are washdown grade. makes a world of difference, as they have all been in constant, demanding service for about a decade. it gets HOT in there, but there have been no vfd failures in the company's history. in my opinion, if you're going to go the route of modernizing and installing a vfd, you might as well go the extra mile and make sure it's safe and comfortable in its environment. they are so important to cutting down on energy costs. plus, come on. vfds are so COOL! installers should WANT to install them properly.
those Fuji IPMs, also, are fantastic, and should last for a good long while. it really does help to have the gate drive circuitry operating under carefully established conditions like that. Fuji equips all of their vfds with their house-made igbt IPMs, and that really drives the cost and size of the units down. i've got a fuji vfd in my home that i installed to run a modified shroud fan, that i never really have to turn up to more than 3/4 speed. i took the risk on it, and am now completely in love with their drives!
