Good morning
I'm trying to get hold of a drive to control a three coil four wire unipolar (I think) stepper. I've come to understand that this isn't exactly the most common type of stepper, and therefore the search is proving kinda difficult. I'm completely useless with electronics, so building a drive myself isn't something I'd like to do, but it's not out of the question as a last resort.
The coils have a resistance of 33 ohms each, and they're arranged like this:

That means it's unipolar, right?
The voltage used to excite the coils is 28V, so the current per phase is around 850mA
Could any of you point me to a drive that would work with this thing? I've found nothing so far.
Thanks a lot.
