I'm affraid that's the problem Chris ! In this case we are all using our brains with these replications, and wire the 2 motor coils to move the rotor in the same direction. That's what I was going to do, and that's the sensible thing to do! But what do you know, being careless and stupid might have it's benefits after all! (I'm not saying Romero is stupid, this is a retorical statement) In RomeroUK's dynamo one motor coil wants to move it Clockwise and the other Couterclockwise, (read what Peter found out) Who in their right mind would configure a rotor like that? You see, the jerking back and forth of the rotor, when power is turned on is a VERY BIG CLUE, which again was missed. For comparison, DC fan motors in PC's are designed about the same as this dynamo, and it uses hall sensors too, and IT STARTS RIGHT UP, NONE OF THIS JERKING BACK AND FORTH AS POWER IS APPLIED. After power is applied, than RomeroUK has to stick his hand in there and manualy start the rotor going CLOCKWISE and free it from this jerking motion.
It will all sink in slowly, give it time.
