Tony, you don't need much theory in this case, 15 is an odd number, the number of magnetpoles must be even for symmetry/balance reasons. Otherwise, somewhere on the ring, you would end up with two neighbouring magnets having the same polarity.

The stator has to have 3,9,12,etc. teeth because we use 3-phase controllers. Were we using 5-phase controllers, the number of teeth should be a multiple of 5.
