"24V DC Cooling Fan" frequency increases, the coil resistance increases, when the number of poles as coils originally low supersaturation, the number of turns is too small, current, power consumption, because the resistance is now increasing, and therefore, the current can be reduced a. In fact, a very high number of "24V DC Cooling Fan", for low-speed fan, the dead will be improved, because of the high number of poles of the motor coil current of fast switching, instant high kinetic energy, "24V DC Cooling Fan" driven by a motor launch the force is high, so the dead will be much better than the low number of poles.
