I bought a 6 wire stepper motor. it has RED-RED-BLACK-BROWN-ORANGE-YELLOW wires. i connect both red on +5v. other 4 on ULN2003. now, in which order should i supply pulse to make it run on one direction? i use embedded C in pic controller. i tried in different order but it oscillates never run in one direction.

Here is the sequence
1000
0100
0010
0001
and again 1000
loop it...
 

I tried this. but its not working as such.
its running forward when
1000
0100 is looped.
its running reverse when
0010
0001 is looped

its oscillates clockwise and anticlockwise in 2 steps when
1000
0100
0010
0001 is looped.

is this really stepper motor or the shop guy cheated me? if stepper motor, y does it runs this way? what the solution for this?
 

You will need to identify the specific windings in order to determine the correct sequence. Is there a manufacturer name on the case? May I suggest googling "stepper motor cable color code {manufacturer}"?

Here is a good description of **broken link removed** If you look and follow other links on the page, this reference also tells how to identify the coils and their associated color-coded wires.

Look sharp! The sequence should power alternatingly the upper and lower winding pair. So the correct sequence is
e.g.
1000 (ye)
0010 (bn)
0100 (or)
0001 (bk)

or

1000 (ye)
0001 (bk)
0100 (or)
0010 (bn)
 
@djsfantasi-> behind the motor, its specified as FDK J58A832T.

@All -> Kindly see picture and tell, is that really stepper motor? or any other motor?

Yes it is 7.5 Degree per step Unipolar stepper motor from FDK but the model is obsolete now and not manufactured anymore. The two red wires (One from top coil and one from the bottom coil) are common and rest wires are as sequence as mentioned by "Fvm". The datasheet is not available.
 
Finally worked. :smile:

@FVM-> Thanks a lot. ur second sequence worked
@Pranam-> Thanks for info,...
@all -> Thanks for finally making it work.

Congrats on your sucess. But it'll be still great if you can share your project for the benefit of all the members.

its not a big project. just trying my first project. so, doing automatic railway gate controller. thats all :)

May be its a small project but there are ample members who ask questions like the one you asked..Just to run a stepper motor. Hope your reply will help such members.
