4 magnet (technically two pole split magnet) reduces the strength of the magnets. This reduces the torque and saturation point of the motor, but also increases low speed resolution just a touch. 2 magnet has higher torque and lower speed, and a bit better efficiency. Assuming the flux density of the magnetic material doesn't change, nor any of the other motor components. |

For 540 motors, it doesn't have a limit.
