Problems solved by technology

[0006] However, since the silicon steel sheets 12 and the winding wires 13 of the stator structure are arranged separately and juxtaposed between the fan frame 15 and the fan blades 14, and the groove teeth of the silicon steel sheets 12 occupy the space inside the fan frame 15, the air inlet and the air inlet of the fan 1 are directly reduced. The air outlet area indirectly reduces the air volume that fan 1 can discharge
In addition, the winding wire 13 needs to be wound with the silicon steel sheet 12 respectively, which will increase the production and manufacturing cost of the fan 1

Abstract

The invention discloses a motor which comprises a rotor magnet ring, a stator iron core, a first silicon steel sheet, and a second silicon steel sheet. The stator iron core is arranged outside the rotor magnet ring. The first silicon steel sheet is ring-shaped, arranged on an upper side of the stator iron core and provided with at least one first magnetic pole. The second silicon steel sheet is ring-shaped, arranged on a lower side of the stator iron core and provided with at least one second magnetic pole. The first magnetic pole and the second magnetic pole are arranged in the projection direction in a staggered mode. The invention further discloses a fan with the motor.

Description

[0001] This invention is a divisional application of the Chinese invention patent application (application number: 200810002944.7, application date: January 11, 2008, invention name: fan and its motor). technical field [0002] The invention relates to a fan and its motor, in particular to a fan and its inner rotor motor. Background technique [0003] The volume of the current fans used in electronic devices or electronic systems tends to be thinner and smaller. In the limited volume of products, it is necessary to improve the heat dissipation performance of the fans. In order to improve the heat dissipation performance of the fan, one of the important improvement methods is to adjust the fan blade area of ​​the fan. [0004] Generally speaking, fan motors can be classified into outer rotor motors and inner rotor motors according to the arrangement of the rotor structure and the stator structure. [0005] Please refer to figure 1 As shown, an existing fan 1 uses an inner r...
