I purchased a stepper motor which says:
STH39H2002
3.75deg/step 6.9 hm
I could not find its datasheet and hence dunno wat type of stepper motor it is. and the safe voltage and current limits. I need the details at the earliest. thanks
A manufacturer's name, or a photo of the symbol would help a lot. We can guess at the size (and therefore the power rating) if you provide some measurements. Finally, the number and color of the wires is helpful.
