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

 

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.

I have a couple of poorly made videos :) that show how I am playing with
steppers

[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.

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.

[Amateur-repairs] Re: Precision test equipment

 

Thank you guys...

The Model Num is 22-163. No english suport from RS.

Yeah, its a lot 'o current to draw overnight.

I was thinking of grabing an old 3v wall wart to power this thing; its paid for and why knot? But if I do that, why not just use the HP 400D ???? ??

Anyways, I hate tossing stuff if it can be fixed. I guess i'll buy a Fluke or grab a Simpson 260.
