    Hello,

    Does anybody know what power ratings of transformer are for the following stepper motor using?

    - 3 pieces of unipolar type, each one is of DC 2A, 1.8ohm, 2 phases.
    - each driver board consists of 4 pieces of TIP122 with each collector goes to individual wirings, wheares two pairs of TIP122s' emitters connector together to a 0.5ohm resistor to ground.

    Thanks in advance.
