Well, I think the Keling motors are actually 4 pole.  That means there 
are 4 poles for
EACH phase, or 12 sets of windings on the motor.  Each phase goes to 4 
windings
in series.  (You might call this a 12-pole motor, but electrical 
engineers group these
together and call it a 4-pole motor.)  If you apply current to one 
phase, the motor
will "stick" in two positions.
