How to determing pole pairs?

How excactly do we determing pole pairs on our esk8 motors ? I know it’s usually 7 pole pairs. But this motor made me doubt. It has 14 magnets and 12 motor Windings. IMG_20180820_191358

12/3 = 4 poles per phase on stator side. 14 magnets = 7 pole pairs on rotor side < - guessing thats what you’re after?

Yes thanks… that gave me a little bit better e-rpm and KV numbers (lower) :slight_smile: I was afraid it was 6 pole pairs

Found some bedtime stories here :

It doesnt cover outrunners but still gives pretty great explainations :slight_smile:
