6 Wire Stepper motor, NMB-MAT PM42S-048

I am having a 6 wired stepper motor, NMB-MAT PM42S-048 which i am trying to connect to Arduino. I searched for data sheets but wasn't able to find any related help. All i got was the 4 wire having different wire color code details. I am confused and not able to understand how i can control it.
CAn you please guide me, how can i do it so?

That sounds like a unipolar stepper motor. It has two center-tapped phases. You connect the center taps to a power source and then switch the the ends of the coils to ground in sequence in order to turn the motor. See Jones on Stepping Motors for Doug Jones's exhaustive stepper motor tutorial.
