RE: [Electronics_101] How do I test a stepper motor

 

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

Jamie,

Thanks for the videos, they are a big help. I am so visual that reading
things like this just doesn't get. A video like this makes things pretty
clear.

[Electronics_101] Re: How do I test a stepper motor

 

if you have two identical ( or very similar) and if you just want to test for wire continuity. wire two together.

Then put a knob on one, and an indicator on another.

manually spin one. the other sill spin exactly in step.

there are a lot of stepper drivers in the CNC market. you do not have to build one if you do not mind spending the $$$

there are a few chips available for this purpose as well. interestingly enough there were driver circuits on the printers.
