Three cheers for Patrick!
I'm impressed at the level of detail. You wont find any other esc and bl motor manufacturer giving this level of info and care to their obsessed customers. Simply amazing. Oh...I might be asking for more info... let me just swallow this first.
The material plays a role in the eddy current losses - It should be non conductive ferrous/magnetic type material and the higher the switching freq the higher the eddy currents... I need to look up the equations from years back...
At the moment gut feel looks like: BL Motor Efficiency losses accountable by
80% resistive (wire), 7% eddy current, 7% magnetic saturation, (rest on other losses such as variable load/good&bad gearing/)...??
Open to suggestions...
I'm pretty sure this will not be linear. I'm gonna see if we can work out the math so we can do an accurate simulation plot & material swap/switchout compensation test... Maybe I'll get bored before I finish this project..lets see.
