Yea I remember that too. Not sure how that redundancy scenario would work with this motor. There doesn't seem to be anything mysterious about this motor-I've applied 12 volts to one of the six coils and the motor twitched hard, went to a certain position and stayed there. Then I applied 12volts to the opposite coil and the shaft was energized but didn't move. All seems normal. I just new to drive the motor given what I know now though.
