I am wanting to make a thing move at a set speed. The speed must be able to be adjusted.
I have a ballscrew and slide, which I have used a 270oz stepper motor to push this thing along and it worked. This was hooked up to a PC running Mach3 to drive it.
Lugging around a computer is not practical for this application. So I figure a simple motor speed controller will do. Then I can just get a motor and hook it up to 12V and the motor controller and away I go.
Ideally it would be nice if I had a LCD screen where it would show the travel speed. A PWM motor controller from what I have seen so far will give a reading in %, not in mm per min.
Would it be easy to make it display mm/min instead of the %. I would have to workout how many revolutions of the motor shaft move it 1mm etc.
I have used the 270oz stepper and it moved it with enough power. So how do you know what size motor to get that will have the same power?
I guess running it on 12v is easier. Does the motor need to have brushes? Can I uses the stepper motor? (only trying to save money here)
Where can I go to find an equivalent sized motor?
