The number of poles is always even, since every north pole must return magnetic flux to a south pole.
Generally, a motor with a higher pole count will run slower and develop higher torque than another motor with a lower pole count, assuming that both motors are the same size and are rated for the same operating voltage and continuous-duty current.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
