Stepper Motor Wiring

[Zeeflyboy]

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!

you need to use a multimeter ( or a simple battery & bulb continuity tester )to confirm which two wires goes to each motor winding

if you find you have 3 ohms or so between the red & yellow wires connect them to A+ and A- on your driver

you should then find you that you have 3 ohms or so between the
blue & green wires which you should connect them to B+ and B- on the stepper driver

not all stepper drivers have the required fault protection to survive any connection between the A & B terminals

if you find the motor runs the wrong way you can either change it in the controllers software - eg mach 3 changing the direction pin from active high to active low
or
reversing the wires on one winding
eg
changing from
red to A+ and yellow to A-
to
red to A- and yellow to A+

Take any 2 wires from the 4 and cross them together and try and turn the motor shaft. When you feel resistance you have a matched pair. (The stepper's are working as a generator)

Then wire 2 pairs next to each other in the 4 pin connector.

Try it if the motor's run the wrong way either swap the wires around or change the setting in the firmware to invert axis.
