Good morning,
I have previously run through all 36 combinations with the same result, the only non rough forward spinning combinations will not exceed approximately 8mph. I am also using a brushlessmotor controller tester, I tested the motor windings and they were fine, I tested the motor hall sensors and they were fine, using the tester I established the combination of hall sensors which gave me correct sequence A, A&B, B, B&C, C, C&A. I then went through the six combinations of phase wires of which only one was both forward and smooth, and this combination will not exceed 8mph. I also used the tester to check the controller and it checked fine, I checked the throttle and it is fine. I have used another throttle and another motor of the same type with the same results. Its got me beat.
thanks
Paul
