Stepper Motor Wiring

[ravihotwok]

Hello,

I am having to rewire my stepper motors, the motors themselves have 4 wires:

red
yellow
blue
green


Are these all the same on each motor? Im just not sure which pins to wire them too on the control box you see

not always the same I'm afraid. I've had to switch single pairs of wires around before.

Do you have a model number on the stepper so you could google search a manual?

Manual? christ chance would be a fine think lol.

Motors have this labelled on them:

Anchuan
57HD0401-15SB
1.8 2OA N1606

Will it do any damage to the circuitry in the control box or the stepper motor if I just try trial and error ? or would it be impossible to work out?

Cheers

Do you own a multimeter?

You just need to match your pairs really then polarity can be trial and error... see this guide here if you need help with how to do it:

Mate that is very very helpful. Im just trying to sort some 4 core cable out from somewhere then I will get investigating.

Cheers pal

No problem.

Just actually found this which is perhaps a slightly clearer explanation (especially regarding direction) and gives some other techniques if you lack a multimeter... though I'm not sure I would trust the complete trial and error one with expensive drivers/motors, but that's just my paranoia probably!
