Hello Christian I can check. no-load data is not related to dyno however (torque=0) The equation set I am using is a bit different from yours, so the relations...
Hello Christian I have put the motors: Plettenberg Orbit 20-16 and 25-16 at 10V and 12V into Dcalc (Excel- version V221_026). I see there, efficiency is also...

Hi Christian In my measurements, no load is not of real relevance. So I am not looking much at it. I tried to vary the no load data in Dcalc, just to see what...

Hi Christian I checked now the dyno. The result: the precision is +-1g or 1% whatever is worse. This transfers to 0.1Ncm in torque or 1% whatever is worse. I...
