Hi guys,
I have a rotating disk (7.5cm radius) with three holes 120 degrees apart at 5cm from its center. The total mass of the disk is about 1Kg.
I want to rotate this disk by an electric motor and stop each hole at the same point, i.e rotate by 120 degrees, stop (first hole), rotate by 120 degrees, stop (second hole), rotate by 120 degrees, stop (third hole) and so on.
At its best, it has to complete a revolution per second. Thus, it has to start/stop fast and with an accuracy of 0.1mm.
What type of motor do you suggest, stepper or servo?
