We have started tweaking the IONI drive in order to push it beyond it’s present output current limits. This includes testing of lower loss power MOSFETs and current sensing resistors to achieve reduced heat dissipation. So far we have achieved 35-40% reduction of heat dissipation at high currents.
MOSFET replacement work in progress. The new ones are already installed on right side. These particular transistors have exposed top side thermal pad for external heat sinking.
Great news! What’s the estimated max current?
It’s to be determined, but there will be post about it once we have completed the testing. My guess is that max could be 22-25A.
PoS or RMS?
Moro Tero,
Great news indeed, 22A will be great, 25A will put us in sim racing heaven. Then we can drive our servos like the big MiGe and Lenze to their maximum capacity, fantastic effort!
Would be good if you can provide mounting holes for some external passive heat sinking!
Enjoy, talk soon.

Did you get my reply about CPU watercoolers Tero?
I found something like a few weeks ago, but you did in-depth research,
along with your post seems to be more compelling than the others.
I am astounded with the arguments you provided as well as the manner of
your post. I enjoy when posts are both interesting and informative,
when even boring details are presented in an interactive manner.
Well, it’s definitely about your article.
I truly enjoyed that one, since it’s full of interesting facts and it’s a kind of easygoing article.
I spent only a couple of minutes studying, and due
to well-structured text, I understand it entirely.
Thanks!
