Problems solved by technology

[0003] However, with the miniaturization of electronic devices, the housing space of the fan is also reduced, thereby reducing the size of the fan
When the size of the fan is reduced, the contact area between the stator sleeve and the bottom plate will be greatly reduced, and the joint force between the stator sleeve and the bottom plate will be greatly reduced, which will cause the problems of detachment, deviation, and damage of the fan during rotation

Embodiment Construction

[0036] figure 1 A schematic diagram of a fan 100 according to a first preferred embodiment of the present invention is shown. figure 2 A top view of the stator base 108 of a preferred embodiment of the present invention is shown. image 3 show figure 2 The schematic diagram of the A-A section. Please also refer to Figure 1 to Figure 3 , the fan 100 is composed of a motor and at least one fan blade 120 surrounding the motor. The fan 100 can be an axial fan, a side blow fan or a diagonal flow fan.

[0037] The motor is composed of a stator structure and a rotor 132 . The motor provides the power for the fan 100 to operate. The stator structure is composed of a stator base 108 and a stator pole set 148 .

[0038] The stator base 108 has a base body 102 and a barrel portion 104 , wherein the base body 102 and the barrel portion 104 are integrally formed. The surface of the base body 102 has at least one air hole 136 , and the air hole 136 penetrates the base body 102 for ...

Abstract

The disclosed fan includes a stator seat, a rotor, at least a leaf blade, at least an upper pole piece, at least a lower pole piece, at least winding with wire being wrapped in axial direction, and awall part. The stator includes a seat body and a drum part. The drum part is setup on surface of the seat body. There is an axle hole inside the drum. The seat body and the drum part are integrative prepared. Rotor encircles the drum part, and a rotating shaft penetrates into the axle hole. Leaf blades are setup around circumference of rotor. Upper pole pieces and lower pole pieces are setup on upper portion and lower portion of the drum. The said winding is placed between upper pole pieces and lower pole pieces, and the wall part surrounds circumference of the stator seat.

Description

technical field [0001] The invention relates to a fan, a motor and its stator structure, in particular to an integrally formed stator seat and the fan, motor and its stator structure with the stator seat. Background technique [0002] In today's electronic devices, considering cost and heat dissipation efficiency, fans are generally used as heat dissipation tools. Current fan manufacturing methods, such as Taiwan Patent No. 506655, Taiwan Patent No. 539346, Taiwan Patent No. 517429, Taiwan Patent No. 434980, U.S. Patent No. 6530746, U.S. Patent No. The methods used in Patent No. 6652246, Japanese Patent No. 2590462, US Patent No. 6050786, and US Patent No. 6193478 are to form base plates and stator sleeves of different materials, and then fit the stator sleeves to the base plate in the center hole of the to form the stator base. [0003] However, with the miniaturization of electronic devices, the accommodating space of the fan is also reduced, so that the size of the fan ...
