Sorry, I recently had the most unusual experience with a micro stepper motor out of a digital camera I was trying to repair for a friend. No matter how I tried I couldn't read any coil resistance and we tried
numerous times with a quality multimeter (my son and I). The strangest thing happened I can not possibly explain, the motor was somehow stuck between poles and after rotating the shaft manually started working properly. This after applying a direct signal to the motor and still nothing.
It's beyond any feasible explanation I can come up with, with the coils appearing to be burnt out (open circuit) but the camera went back together and was returned to one very happy owner free of charge (a good friend) after he'd told me not to waste the time and maybe just throw it out.
