I got a few motor similar to the image below from a old scanner and I want to apply them in a robotic arm to move the arm because BLDC motors have a large torque I then control with arduino. Well, in order to do that I came across that maybe I would need to control their position moving at 60 rpm would be a reasonable speed (PID controller right?). Also the specification of a similar motor is at the link below to more informations.
Where I can find a step-by-step instructions to build my own PID like hardware needed, electrical circuit used, etcc?
I really appreciate your support guys!!
