ABB DCS400 - 900A / 522kW DC Motor Drive Teardown

[@TMaxElectronics]

Interesting to see the construction still being very similar to the old bbc Veritron drives. Just without that crusty (but apparently pretty advanced) discrete pid board on top 😂

[@fogelmclovin6815]

those ratings and connectors are crazy!

[@KaizerPowerElectronicsDk]

And if it wasnt for the massive forced air cooling, those busbars needed to be larger :)

[@bluetrepidation]

You can run these in a DC power pupply mode if that is more useful.

[@T2D.SteveArcs]

Wow, now thats a rectifier 😂

[@KaizerPowerElectronicsDk]

Large motor would be around 0.5m x 0.5m x 1.5m :O www.drivesandautomation.com/product/dc-motors/sicme-motori-ra-series-dc-motors/sicme-motori-ra-series-dc-motor-280-frame-400v-476kw-1423-rpm/

If there were a catastrophic internal breakdown - I'm not sure the case would be strong enough to contain it?

[@KaizerPowerElectronicsDk]

Not even remotely. This would burn right through the 2 mm steel plate :)

[@rfekztjpkrpd4988]

So this does not do any PFC? Isn't that an issue in these power range?

[@KaizerPowerElectronicsDk]

It is an issue. But the size of the filters, tuned harmonic filters, is too great to fit in the drive. It is external and here is a short article on it powerquality.blog/2022/03/15/power-factor-correction-and-harmonic-control-for-dc-drive-loads/

@@KaizerPowerElectronicsDk That shunt reactor is forcing the highest frequency noise starting at the 5th harmonic to enter the power grid. Thought they would've used series L and shunt C, with the output-to-plant from the C. Resonances can be damped with an additional series RC connected across the shunt C. More costly, but more satisfying.

Made in Germany. 👍💪

[@WacKEDmaN]

nice vid!.. bit of a chunky beast ya got there! :P

[@KaizerPowerElectronicsDk]

38kg of madness and 1.5kg per brick!

[@Alexelectricalengineering]

More then 500 kW, so cool 😎😎👍👍

[@KaizerPowerElectronicsDk]

Should I have written 0.5 MW? ;)

[@Alexelectricalengineering]

@@KaizerPowerElectronicsDk sounds even more epic :D

[@ljubomirculibrk4097]

If that monster for those giant escavators in open field coal mine? 15A to drive ouput 😅

[@KaizerPowerElectronicsDk]

A driver to drive my driver to drive my bridge :)

[@Tiolych]

Is such a module powerful enough to control the speed of a computer fan? )))

[@KaizerPowerElectronicsDk]

It can run a fan. But please do not try to overclock your CPU!
