That is this in runner here, right?

As I understand in runner motors, the windings should be slightly over lapping each other and wrapped around the inside of the "can" or motor housing. And the rotating part is the magnets so count the number of those will tell you the pole count.

Each of the magnets will have a North pole on one end and a South pole on the other but the pole count will be the number of magnets, not the number of N and S ends.

Can you do some basic trouble shooting with a multimeter? If so, check the resistance on the three terminating lugs (1-2, 1-3, 2-3) and see if they are all the same and that they have steady readings. And then check each of the lugs for shorts to the housing.
