DC Fan Structure and magnetic stripe

"DC Fan" mainly by the framework ﹑ blades (including magnetic stripe) ﹑ PCB board (including ATS277, etc), consisting of four parts of the stator (STATOR line package and magnet). Magnetizing the magnetic stripe is made from special materials magnetized magnetic stripe can be set to a quadrupole, magnetic stripe will expand as shown in Figure 1; generally magnetic strip end to end to form a ring, placed inside the fan box. Magnetizing the magnetic stripe is generally divided into charge (maximum magnetic field strength inside of the magnetic strip) and an outer charge (maximum magnetic field strength of the outer magnetic stripe) in two ways 6CM more fans are used in the charge mode, 5CM or less using internal or external charge charge in two ways. Magnetization intensity is generally based on the size of the fan decides.
