I did wonder if the light bulb itself likes being operated at below
full power. Some bulbs do not like this. then metal is deposited on the
glass case and it is dead sooner. If someone knows that please tell me..
I have the original motor still, and the gearchain.
it is a brushless DC motor, the controller refuses work.
I'm by coincidence just now working on a model plane
brushless controller, maybe the first prototype may be used for it
(with bigger transistors than in the planes).
you could see it as a strange stepper motor, and drive it
with a fixed pattern synced but i think this is a bad idea.
