Hello everyone, i am pretty new to this world of Arduino and electronics in general. Recently i got my first board (UNO) and noticed at my workplace that had some printers i could salvage parts from. As i did it, i managed to collect many motors (about 10 from two printers) all of them are pretty common. They consist of a DC Motor and some other stuff. I ve read on this forum that they are this way to behave like stepper motors. But i didnt manage to make them work as one would like to. The white/yellow cables are the classic DC motor cables and when i plug them into a battery it is working perfectly as a DC motor. Any help or at least some guidelines about the process i should follow to understand how to make them operate as steppers motors and controll them with my UNO?
Thanks in advance.
That can't really work exactly as a stepper. But it has a position encoder (the thing with the perforated disk attached), so the controller can sense exactly how far it rotates when running.

Your post calls for full time work to handle. Most helpers will not go for it.
...and how exactly is that? What are you thinking of using them for?
As i have 10 motors i would like to built a 3-4DoF robotic arm just for fun, so i would like to manage the angle precisesly
Test your motor by mounting it so it cannot turn or move. Attach a lever to the arm and a small weight to the lever. When you have a controller board that can move the motor and arm and HOLD the arm in place, write a program to make the arm move as you think your project arm would move.
When that works as you want, then begin to study how to make the arm move to a precise angle and, I guess, hold that angle.
It doesn't look like a geared motor. Isn't it a high speed motor that needs gears to produce robot-compatible torque? I doubt that it could lift or hold a robotic armature by itself.
Thanks everyone for the answers. I appreciate each and every one of you.
That's a pretty advanced project even when you have well-documented parts to build it with.
Trying to reverse engineer salvaged parts requires a lot of experience.
Maybe start with something simpler ... ?
@jim-p jim is there a way to PM you ?
would you mind giving me some instructions on how to make the circuit, i am pretty newbie and that would help a lot
I was wrong, it's not a uni-polar stepper.
Have no idea how to make it work.
