hoping someone can help me out, i have 3 sanyo denki step-syn stepper motors that i would like to use in some sort of project. they are type 103G770-2517 dc 4.1v 1.1a 1.8 deg./step. i was wondering if anyone had any info or knew where to find any info on these, and more importantly, what driver to use or how to choose the right driver for these steppers. any help would be greatly appreciated. thanks
