How to determine the pole count of a mmm motor

[brainanator]

I've got a medusa 540 4 pole motor (pretty sure....lol)

Yes Medusa are 4 pole
Neu 4 pole
Feigao 2 pole
Novak 2 pole
Tekin T8 motors 4 pole
all other Tekin to my knowledge are 2 pole as
Roar approved 540 sensored motors are all 2 pole to the best of my knowledge

You just have to count the magnetic heavy point when you do one complete rotation of the rotor (hope it means what it means in french...). Usually, a 4 poles motor will have 12 points, 2 poles 6 points.

12 points because motor stator have 12 slot ~~~

Of course, but 4 poles motor have generally or always 12 slots.

Pretty much true, but Medusa as an exception, their motors have 9 slot stator and 4 pole rotors.

And they are 12 points too, so it's not the slot count determine the points, it's 3x rotor pole count.
