Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the technical solution clearer, the technical solution will be further described in detail below in conjunction with specific embodiments. It should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the technical solution.

[0022] The present invention discloses a shaded pole fan stator structure that can reduce the natural vibration of the fan and improve the reliability of the fan. The assembly 1 includes a housing 10 and a stator assembly that is interference-connected with the housing 10. The stator assembly includes a stator core 11 and a stator winding. The stator winding is wound on the stator core 11. The stator core 11 is made of laminated stator punches. , the stator punching piece is fixed by rivets 14, and the rivet 14 runs through the stator core 11 to increase the strength of the stator core 11; the upper end of the stator core 11 is fixed...

Abstract

The invention discloses a ground electronic equipment shaded pole type fan stator structure. The structure comprises a shell assembly and a rotor assembly, the rotor assembly is connected with the shell assembly through a bearing, the shell assembly comprises a shell and a stator assembly in interference connection with the shell, the stator assembly comprises a stator iron core and a stator winding, the stator winding is wound on the stator iron core, the stator iron core is formed by laminating stator punching sheets, the stator punching sheets are fixed through rivets, and the rivets penetrate through the stator iron core and are used for increasing the strength of the stator iron core; an upper end sheet is fixed at the upper end of the stator iron core, and a lower end sheet is fixed at the lower end of the stator iron core; and a magnetic conductive sheet is arranged at a notch of the stator iron core and is used for improving the magnetic conductivity. According to the ground electronic equipment shaded pole type fan stator structure, self-vibration of a fan can be reduced, and the reliability of the fan is improved.

Description

technical field [0001] The invention relates to the technical field of a shaded pole fan, in particular to a stator structure of a shaded pole fan for ground electronic equipment. Background technique [0002] At present, the research and development of shaded pole fans in China is less, and they mainly rely on imports from abroad, resulting in high costs. In the prior art, there is also the problem that the fan has a large degree of natural vibration, resulting in low reliability of the overall structure. Contents of the invention [0003] In order to solve the above problems, the present invention provides a shaded pole fan stator structure that can reduce the natural vibration of the fan and improve the reliability of the fan. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: it includes a housing assembly, a rotor assembly, and the rotor assembly is connected to the housing assembly through a bearing, wherein th...
