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 😂
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/
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.

those ratings and connectors are crazy!
And if it wasnt for the massive forced air cooling, those busbars needed to be larger :)
You can run these in a DC power pupply mode if that is more useful.
Wow, now thats a rectifier 😂

If there were a catastrophic internal breakdown - I'm not sure the case would be strong enough to contain it?
Not even remotely. This would burn right through the 2 mm steel plate :)
Made in Germany. 👍💪
So this does not do any PFC? Isn't that an issue in these power range?

nice vid!.. bit of a chunky beast ya got there! :P
38kg of madness and 1.5kg per brick!
More then 500 kW, so cool 😎😎👍👍
Should I have written 0.5 MW? ;)
@@KaizerPowerElectronicsDk sounds even more epic :D
If that monster for those giant escavators in open field coal mine?
15A to drive ouput 😅
A driver to drive my driver to drive my bridge :)
Is such a module powerful enough to control the speed of a computer fan? )))
It can run a fan. But please do not try to overclock your CPU!
