That, is not realistic. Even with another similar motor, nobody would power a 26 lbs motor with a 20A controller.
It was a quick illustration of winding by itself multiplying output torque by more than 2X. I picked that motor because it’s one that has a large % variation of winding available in the simulator.
These results do raise the question: Why does a change in winding affect torque more in some cases than in others? Is it the controller multiplying phase current more for a low impedance motor? Torque per amp fed to the motor should vary in more or less direct proportion to the number of turns, given the same copper fill. So when that doesn’t happen, is it only the controller trading amps for volts, or is there something else at work?
The 5302 is not in the simulator, not in the latest version at least, and was never sold by Crystalyte. This was a mod that some had done to double the kv of the 5304. The 5305 had been sold by special group order with the 5306 (of which I got one).
The numbers are from the old simulator, that had mistakes in the results. There are still some, but fewer because a lot of work had been spent to collect true data.
