Have you been able to heat your controller so you need extra cooling?ElectricGod wrote: ↑Dec 20 2019 4:30pm
I'm toying with the idea...no actual action yet.
The controller is limited by heat build-up.
The shell can dump heat at it's size only so quickly.
More heat sinking at the heat spreaders and the mosfets can deal out more amperage and live.
What I'm toying with is adding external heat spreaders.
This will allow me to add a much larger heat sink under the controller.
The controller would remain exactly as is from Nucular.
Nothing added would change the controller in any way.
It would all bolt on right in place where the current heat spreader screws are now.
After that, cooling can be expanded any way you like.
I'm thinking a water jacket, pump and radiator.
There's no reason the mosfets can't deal with 500 phase amps continuous if they stay cool.
I have only done a few test runs in the woods in cold, wet and dirty conditions. So it has good conditions to stay cool, and my bike is not very heavy. In these conditions it was just 20 degrees C, my previous controller got to about 85 degrees C in the same conditions.
Sure, if you go fast for a long time with a heavy vehicle you would probably be able to get it hot.
