well on a first note I watch the video and it helped I could verify that there were to continuous coils 6 to 9 ohms depending on the stepper motor. As for the H bridges I didn't quite know what to make of that but all three stepper motors had a coil between 1 and 3 and 2 and 4 and if I applied power between 1 and 3 it snapped to the next step also the same with two and four it then locks in that position.so would you guys say they all work?terramir

Hi Terramir,
Normally, 4 wires stepper are bipolar motors. If so, you will need H Bridge
Stepper Driver. Just Google it. He is a good page on the difference.

Subject: [Electronics_101] How do I test a stepper motor
Well I am collecting stepper motors from printers and such and I know to
make real use of them I need a stepper controller IC and some kind of
processor program etc. That's ok got the scematic parts are coming and well
gonna slap that together etc to finish 14th of febuary if everything goes
right. but what I need to know if how I can check out stepper motors very
simply to verify functionality . there are 4 wire hybrid stepper motors 17pm
type with 4 contacts. just want to run checks on them before I get going too
far to see if I'll have to buy other ones.
Let me know
yea been busy haven't posted in ages
