In the technical reference is states that the number of pole pairs is 6 which means 12 poles. It also states that when the motor is spinning at 6000 rpm or 100 Hz that the electrical frequency is 300 Hz. From the equation w_e = w_m*(#of poles)/2, it seems that the number of poles is actually only 6. So are there 6 poles or 6 pole pairs?
Motor has 8 poles. Information updated in the technical reference document.
