"Cooling Fan Manufacturer" Let DC fan frequency increases, the coil resistance increases when the number of poles as the previous low supersaturation coil, number of turns is too small, current, power consumption, and now because of the resistance increases, therefore, the current also can be reduced. In fact, a very high number of fans, for low speed "Cooling Fan Manufacturer", the dead will be improved, because of the high number of poles of the motor coil current of fast switching, instant high kinetic energy to drive high power motor to start, so the dead will much better than the low number of poles. The stator structure of the motor section (the stator), after the power input, will generate an induced magnetic field lines, and the control of the driving circuit between the rotor and the stator so that the fan motor is running. Therefore tradition "Cooling Fan Manufacturer" motor structure, only one blade rotor and a stator and a motor drive circuit, and through the shaft and the pivot bearing of access, with the magnetic induction and operation
