The plurality of lower magnetic piece portions i3i are arranged in a staggered manner with the plurality of upper magnetic piece portions 121, and each of the lower magnetic piece portions i3i The top side has a notch 132. When a cooling fan is in operation, its rotational force is mainly derived from the magnetic repulsion effect generated between the permanent magnet of its rotor (not shown) and the motor stator i and the lower magnet = 4121, 131. It is continuously rotated by the magnetic repulsion. However, if it is suddenly affected by other external undue resistance, the rotor is forced to stop, and the permanent magnet of the rotor and the 2 = upper 'lower magnet portions 121, 131 may turn to generate magnetism and effect. After the 'silk force, the (four) material _ depends on the running; therefore, using the notch angle U2 of the upper magnet portion (2) and the lower corner portion 132 of the lower magnet portion 5 M310525 131, the structure makes the permanent magnet of the rotor and the upper The magnetic effect between the lower magnet portions 121 and 131 constitutes a magnetic effect of the unevenness sentence, and even if the external improper resistance forces the rotor to stop rotating, the permanent magnet and the upper and lower magnet portions i2i and i3i form a magnetic attraction phenomenon. The non-uniform magnetic effect becomes the power source that causes the rotor to start again in an instant. It is not necessary to restart the motor power supply or to move the magnet. The magnet and the stator 1 of the motor can naturally rotate, making it permanent, The lower magnetic pieces 121, 131 are generated again
