Turns out there IS a bug in that page: It doesn't work for 8 wire motors. I'll work on it. I tested it again for 5 and 6 wire units and that is fine, as far as I can tell. It's just the 8 wire ones that it doesn't work for.

I have looked at that page many times. My issue is what do the A-, B-, C, and D wires mean? What is their function on the motor? Once I know this I can connect to my driver board.

I know ZERO about electrical shematics.

A- and C are ends of first pair of parallel coils

B- and D are ends of second pair of parallel coils

These coil ends are of same polarity.

What kind of drive do you have?

Ok now I got it figured out, I think. Here is the link to the driver info: http://www.electronics123.net/amazon/datasheet/k179.pdf

Motor info:

A- -- Blue/White
Blue - Red/White

B -- Red

C -- Grn/white
Grn - Black/White

D -- Black

For my board I have to have the two centre wires of the coil joined in order for it to work.

Does this look right?

V+ -- D (Black)
M2B -- ++ (Grn - Black/White)
M1B -- C (Grn/White)

V+ - Power for board
GND - Ground for board

M2A -- B (Red)
M1A -- ++ (Blue - Red/White)
V+ -- A (Blue/White)

KITV - Logic Input

Not right.

It should be like this:

V+ -- Grn + Black/White
M2B -- Black
M1B -- Grn/White

M2A -- Red
M1A -- Blue/White
V+ -- Blue + Red/White

Note also that this driver has no current limiting (according to schematic). If use a high voltage you probably blow up something at low speeds, if you use a low voltage you have low speed. Tip: you could use a 24V car bulb as a current limiter...

I was close, but no cigar.

I have resistors to limit the power for the motor, so I should be alright there.

Thanks for the help kuikkap!!
