controler boards



Well I built the controler board I posted about earlier, in a
wonderfully professionally looking breadboard fassion,  i have beautiful
square waves heading to the TIP120 darlington transistors :),
wonderfull.   The problem is that my motors are getting very hot, im
talking hot.  If I put a lower voltage/phase rated motor on the thing
the TIPs get hot, thats expected, I think,  but im a bit confused about
the way these stepper motors are,  i have one from a floppy drive i tore
apart that gets just warm :), but its weak and its windings are along
with the others are as follows, could some or one of you please explain
to me what it is i have and what it is i need?

disk drive motor

1-----2------3-------4-------5
i connect +12v to say pin 1 which is the lowest common resistance to the
others

any of the other motors that get hot

1------2-------3
4------5-------6
i connect +12v to say 2 and 5  least common resistance between the other
2

I have tried reading about the documentation on other stepper motors and
other types of control boards and
well a lot of the language is abit above my current vocabulary or
knowledge.  Any help would be great :)
