Hi the D-calc approach to estimate Rm is fine, but do not expect to be able to measure Rm with an Ohmmeter. Rm is a virtual resistance which is related to the...
Hello Peter The D-Calc approach of Rm is global and fine ... but not perfect Only due to temperature effect, Rm is variable as the load (and the current)...

Hi Ken yes this is what I have seen as well. D-Calc gives a 5-10% worse efficency as I measure (1% accuracy with dynamometer). It looks that the model does...
Hello Ken I am a satisfied user of D-Calc and it is a very good sheet globally speaking. Christian's opinion (and I agree) is that Rm (internal resistance) is...
