Need help selecting a small motor for moving a small rig back and forth left-to-right only about 1 inch. Answered
I have never worked with motors before, and I am starting to realize that there are dozens if not hundreds of different types of motors.
Imagine two 6" long, 1/2" dia. aluminum rods suspended between two pieces or trapezoidal shaped plywood that are secured to a base and braced to make this whole structure rigid. on these two aluminum rods "rides" a small carriage that is literally just a small 2" x 2" platform made from... whatever... 1/4" plywood. This carriage can slide left and right on these two aluminum rods.
I need a motor that can somehow move this little platform left and right, back and forth, only between 1/8" to 1".
I need to be able to control the speed (rate) at which is travels this small distance.
I also need to be able to control the starting point and the end (return) point.
Basically, I and transferring string from one spool to another. So the platform will have a spool of thread on it, and it will be going left-to-right while another spool is turning. The left-to-right movement will be coordinated with the speed that the second spool is wrapping (turning) so that the thread windes as close to "perfectly" in layers. And each spool will be between 1/8 - 1/4 - up to 1" wide. This is why I need to be able to set the starting point, and the end point where it will stop and reverse direction.
I will be controlling this with a project board like an Arduino. I just need to know what kind of motor to look for, and any other suggestions
