As for the arrangement of the magnetic poles of the two magnetic rings (1, 2-1) and the state of the magnetic force between them, please refer to the sixth figure. The two magnetic regions (21) at the two ends of the ring wall near the ring body are the same as the first magnetic pole (such as the North Pole), while the second magnetic zone (12) is extended outward from the center of the inner ring wall. To the trapezoidal region of the entire outer ring wall, the second magnetic region (12) is configured as a second magnetic pole (such as the South Pole, which is the centerline of the zero boundary between the first and second magnetic regions (11, 12)). 1 3) It is obliquely extended from the outer end angle of the ring body to the near center of the inner ring wall, that is, the center of the inner ring wall is M253703 IV.

Figure 11 shows the magnetic field strength at the near ends of the inner ring wall. The reading is about 300 Gauss, which is slightly different from the central magnetic field. The intensity is the same, but the polarity is North Pole. The magnetic field strength value described above is only a preferred embodiment, and the magnitude and strength relationship are not fixed, but are adjusted according to the radial and axial fixing forces required for practical applications. The measured data can prove that the magnetic configuration of this creation is indeed implementable, and it is actually installed in the cooling fan, and it does not generate any noise, and the vibration level is lower than the human sensible range, which is far lower. The mechanical bearings and magnetic bearings used in practice are an excellent design.
