I have purchased 3 stepper motors from ebay and now need some direction as to a controller (I think). The motors I have are american precision model # M343-07s and the specs are as follows: 4.5 vdc, 3.5 amps class b, these have 9 wires. Iknow these motors are old and probably outdated but they were cheap.
Now my question is this where and what I'm i looking for in order to use these on my router design. I know i need power supply (of some kind) and controller but what size and type should I be looking for? I have no experience with this sort of stuff but and need some help if anyone could guide me as to what or where i can find this stuff please contact me. I have vast knowledge of cnc machining and would like this build to be educational but have no clue on the electronics.
If someone can list the specs i would need to research or let me now model numbers and such I would greatly appriciate it.
