Ideally, we’d be able to adjust the sensor spacing independently of the rotor’s position. Centering the magnetic field in the stator is also important.
When the rotor is or is farther from the sensor board and the variance increases, are we able to verify if the variance we’re seeing is actually the sensor’s ability to read the position of the rotor, and not the instrument’s ability to read the signal? Reason I wonder is as I’ve tested my own motors, I have not detected a correlation between sensor board accuracy and performance of the motor, in my admittedly small sample size. Prior to getting my current 17.5 motor, my fastest 17.5 motor had the “worst” variance.

Will the rotor centering change when the coils are powered, or is it the same as when it is unpowered?
