    Air gap problem in hub motor

    If problem is with smaller air gap than why is 6 turns winding self tune properly in smaller air gap. But 7 turns does not. Is it possible that with 7 turns magnetic flux generated is more than permanent magnet flux and due to this sensor is not able to get proper signal during self tune??

    Also today I faced another problem. I have 2 stators, A and B. Both are exactly same. Even winding on both stator is same as follow:- Number of turns- 7 Number of strands- 10 Wire gauge- 24 swg Slot- 48 Only difference in both motors is of air gap and magnet length. Motor A has total of 1.2mm...
