Stepper motor w Arduino questions

Hey, I’m new to Arduino, and electronics in general, and lately the thing that seems to be stumping me is figuring out how to find datasheets on stepper motors I want to mess around with… does anyone know of a decent site that might make it easier to identify motors? I’ve actually checked and cant find anything.

Just in case any experts are floating around out there, I have a smaller, about 1’ shaft length, what appears to be a unipolar (5-wire) motor.

The tag on it says: fh6-170 Hosiden

hmd4231-010100

made in Japan

01 6da

So far, I’ve found nothing other than it is stocked by copier people as a staple sorter motor, and it did come out of a canon full size copier so that makes sense.

…some of the motors I’ve pulled out of this thing are crazy, most seem to run on 24V and vary amperage, while there are others 38v 0.2a that seem to have one giant step.

The goal is creating a CNC or other machine eventually controlled by arduino, bu who knows?

Do your research to understand the internal wiring of bipolar and unipolar stepper motors. It’s just a matter of checking for continuity between wires to determine the coil setup.

Your best bet is finding a datasheet of a stepper motor of similar size to determine its amperage limit. You can almost always drive a stepper up to ~24V for the best speed, but again, you have to restrict the current the motor consumes. Start at a low amperage and work your way up; when the motor gets to the point that it’s too hot to hold your finger on it for more than a second (after running for a minute or so) then you’ve reached your limit.
