Yankee, i must admit that most of the technical info on the motor you posted is beyond my level of comprehension. The motor i have has an optical shaft encoder just above the windings that controls movement quite precisely as it has at least 150 notches on it. With that type of precision it might not need hall sensors.
jaysettle, thank you for the info, it will take me some time to go through all that documentation (hoping i will understand enough of it to work on 
), but i see it also suggests schematics for a controller...
tks for the suggestions.
