Hi all,
Newbie here..
I'm looking at replacing an old and broken DC motor+gearbox which drive a rotating planet in a Judge Dredd pinball machine. (Very expensive to repair.)
I'm thinking what if I could find a stepper motor with enough torque and control it with the most basic standalone driver (does that even exist?) which I would program once and for all for a specific direction and speed (unknown at this stage, would need to be tuned) and which would simply be activated by the machine's original 12V signal!?
Is that any realistic? What kind of motor and driver should I be looking at? Any view/direction most appreciated!
Thanks a lot!
Anthony
P.S. For those who might know the machine, the planet does actually rotate correctly. Only the disk, which is supposed to rotate the opposite direction, doesn't, due to heavily worn out gears. So the new motor would actually come on top of the existing one. I'm thinking MOSFET if the original motor's driving transistor isn't able to handle two motors.)
