Stepper Motor Connections

[aa5ilmd]

Hello,
I have a stepper motor and I want to control it using a pc but I have a problem with the stepper motor connections.There are six cables and only 3 colors are different other 3 colors are same.You can see in the picture easily.Can you help me?Thanks.

hi,
Its a unipolar motor.
You can see 2 sets of 3 wires.
Measure the resistance of say the first set, the highest resistance is across two pairs of wires are the two phase wires and the centre is the +V supply wire.
Do the same for the other set of 3 wires.


Do you follow this??

EDIT:
Perhaps this drawing will help.
Once you have identified the phases, use a low voltage power supply or 1.5V battery and connect the centre wire of each full winding and touch a phase wire to the other end of the battery.
Note which way the motor spindle jumps a step, repeat for the other windings, this will give you an idea how to connect the transistor drivers so that the motor steps in a rotational motion as each winding is energised.
