i just read through the hall sensor positioning manual crossbreak posted. really nice stuff.
after doing all the math it just showed that the halls need to be positioned 3 slots apart, what they already are. it may be that the distance between them is not 100% exact, but i can't really imagine that.
so i can just do some timing advance to compensate for hall sensor lag and hysteresis. if the kelly controller would be a real FOC controller it would not relate on halls and measure back EMF, which is doesn't seem to do.
i will make a custom hall board that can be moved around and fixed to the motor and do some more testing.
