@PowerGlider, thank you! I have a working code with the old Vesc firmware of a year ago. It already displays the temperatures, unfortunately I rushed the soldering job and pulled an smd pad. Now I can only mount two temperature sensors or reassemble a new vesc with my spare PCB. Two sensors will have to do for testing
I just assume that the copper bar soldered to the fet’s cooling tab has the same temp. The Sensor is currently clamped to the copper bar. I want to keep it simple right now and will leave a larger margin during testruns. A model with junction temperature calculation will have to wait for a future version
@MaxMaker Thanks for the ideas. I have it somehow fitting right now and insultated. Maybe i will even use an endmill in my lathe next time and get both copper planes aligned and then polished like you described.
I’m now working on compiling the new vesc tool software, just this evening.
Thanks again for the support.
