Ok...  I got it figured out.  Mostly...  Its got an independent fan motor.
Doh!  Had I been a bit more observant I would have seen that myself, but
somebody in another group pointed out the possibility, and commented on the
probability because a motor turning only 96 RPM at 3 Hz can't possibly be
turning a fan fast enough to cool itself.

It was easy enough to check.  I spun the fan and held the brake disc on the
motor with my other hand.  Wheeeeeeee!!!

It has six primary leads because there are two motors.

I suspect the 2 smallish brown wires are a thermal sensor.  Not sure I can
test it except maybe...  to wire up the motor and not the fan motor.  LOL.


Life just got easier... if the motor works now.
