Default Stepper motor directions

Hi all,
Is this stepper motor uni directional or bidirectional?
What's the difference between unipolar and bipolar stepper motors?
Thanks

Bi-directional

hi,
A bipolar typically has just 4 wires [effectively 2 coils/windings] and unipolar has 6 wires
, 2 coils, but the coils/windings are centre tapped and are connected to the +V supply.

You should Google for this type of question, theres lot of info and diagrams.
