    i have an stepper motor, vexta, model PH266-02GK, i can not run the motor i have tried alot, how i should know the wire configuration and how should i run it, plz help me it is urgent.
    the motor image is also uploaded.
    the motor is 12v and 0.6A. and 2 phase. bipolar.

    Stepper motors require alternating pulses (there are 2 windings may or may not be center tapped) You have to supply pulses at the appropriate voltage and current and width, and frequency to drive them to your desired need. Stepper motors CANNOT be driven by direct connection to a battery or step down transformer. You must have a drive circuit of some sort. Many off the shelf drivers are available, or you can use a microcontroller with FET's and the power supply necessary to drive the motor. It is not a simple connect the wires and go!
    Sorry, probably not what you wanted to hear.

    Here is a scanned datasheet of your stepper:

    Notice the wire colors and connections at the very bottom of the sheet.
    Note that these are unipolar motors; the yellow and white get connected to +12v.
