Actually you can know the pole number WITHOUT OPENNING the can.
Just rotate the motor shaft, feel how many "detent" in a whole 360 degree round turn.
2-pole rotor will feel 6 detents, that is, 2 polesX 3 stator phases= 6 sticky positions.
4-pole motor will feel 12 detents, same rule, no matter it has a slotted stator or not.
