I watched all 3 hall signals for both bldc components - the one that
works and the one of nonworking. The signal changing order is the
same.
At first I turned each motor so that hall1 is true, remaining 2 are
false. Then I very slowly turned the working motor until any signal
changed (hall3 went true), so then I very slowly turned nonworking
motor until any signal changed status. And all the time they matched
(X is true, blank is false):
hall1 hall2 hall 3
