I felt like using the Grin simulator with my current build specs, just for fun to see how it tracks with my actual performance. But I must not be entering values correctly. Can someone help me out with that?
I've entered what I think are correct values, but results its spitting out are giving me 50% max efficiency and a max power of about 1200w. Which is ridiculous because I'm actually pulling 2-10kw. So it's obviously my fault.
What I have is:
QS273 8000w
Roughly 1500 rpm unloaded at 115v, for a KV of about 0.73
Phase to Phase winding resistance about 1.5 ohms (when measured at the lugs)
28 pole pairs
I am unaware of the inductance, eddie current torque, or hysteresis torque, so I've left those at default values.
Battery I've set to 115v, 90ah, 0 ohms
Controller is set to 300 battery amps, 1000 phase amps
(I'd snap a screenshot but I can't figure that one out either...)
Sorry for being unable to figure this out!
