Not necessarily. Like I said, the number of "notches" you feel in a slotted motor is determined by the number of rotor poles and the number of stator slots.

In the case of a Neu motor (15 series), it has a 12 slot stator and a 4 pole rotor. This motor has 12 notches that you can feel when you turn it. Since the # of poles can divide into the # of slots resulting in a whole number, the number of notches is equal to the number of slots. This works every time. IF you have a motor with say 6 poles and a 12 slot stator you will still feel 12 notches. If you have 4 poles and a 24 slot stator you would feel 24 notches.

AS far as 2 pole slotted motors (Novak, LRP, all the ROAR BL motors) they use a 2 pole rotor and a 3 slot stator. In this case the motor has 6 notches because only one rotor pole can align at a time- 2 poles * 3 slots = 6 notches. I'm not sure if this multiplication method works for any other type of motor. It is just my observation.
