Description

Technical Field

[0001] This utility model relates to motors, and more particularly to a novel high-speed motor. Background Technology

[0002] High-speed motors are commonly used in products such as hair dryers and high-speed fans. For traditional high-speed motors, please refer to the Chinese patent publication document CN208874371U entitled "A Fan Motor with Internally Winded Concentrated Winding". It describes that: "It includes a stator and a winding. The stator has a hollow circular hole in the middle. The edge of the hollow circular hole has eight stator slots arranged in a ring. Stator teeth are provided between two adjacent stator slots. The winding is directly wound on the stator teeth." Traditional high-speed motors usually use an integrated stator with a rubber coating on the stator surface, which results in high manufacturing costs. At the same time, multiple turns of winding are wound inside the stator. During the processing, the winding must be carried out in a narrow space inside the stator, which is not only complicated but also has low production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of high-speed motor that is easy to assemble, saves costs, and improves production efficiency, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A novel high-speed motor includes a sleeve, within which a stator assembly is fixed. A rotor assembly is inserted into the stator assembly. The stator assembly includes an upper support made of insulating material, a lower support made of insulating material, a plurality of iron cores evenly distributed circumferentially, and a plurality of windings corresponding one-to-one with the iron cores. The upper support includes a plurality of downwardly extending upper iron core sleeves, and the lower support includes a plurality of upwardly extending lower iron core sleeves. The upper and lower iron core sleeves are joined together vertically. The upper and lower ends of the iron cores are respectively inserted into the upper and lower iron core sleeves, and the windings are wound around the outside of the upper and lower iron core sleeves.

[0006] Preferably, the upper support includes an upper cavity, the lower support includes a lower cavity, the upper cavity and the lower cavity are vertically aligned and interconnected, and the rotor assembly passes through the upper cavity and the lower cavity.

[0007] Preferably, the iron core is an "I"-shaped iron core including an outer extension and an inner extension.

[0008] Preferably, the upper sleeve of the iron core includes an upper slot with an "I" shaped cross-section, and the lower sleeve of the iron core includes a lower slot with an "I" shaped cross-section, with the upper and lower ends of the iron core respectively disposed in the upper slot and the lower slot.

[0009] Preferably, the outer side of the upper slot has an upper opening, the outer side of the lower slot has a lower opening, and the outer surface of the outer extension is exposed within the upper opening and the lower opening.

[0010] Preferably, the upper end of the upper sleeve of the iron core has an upper cover, the lower end of the lower sleeve of the iron core has a lower cover, and the iron core is clamped between the upper cover and the lower cover.

[0011] Preferably, the upper end of the upper bracket has a plurality of upper limit posts for limiting the winding, and the lower end of the lower bracket has a plurality of lower limit posts for limiting the winding.

[0012] Preferably, the outer side of the sleeve is provided with a housing, and an air guide cavity is formed between the housing and the sleeve.

[0013] Preferably, a spiral air guide plate is provided inside the air guide cavity.

[0014] Preferably, the rotor assembly has fan blades connected to its end.

[0015] In the novel high-speed motor disclosed in this utility model, the sleeve serves as a protective shell for and fixes the stator assembly. The rotor assembly is rotatably disposed inside the stator assembly. The upper and lower supports in the stator assembly are aligned and spliced ​​vertically. A cavity for securing and accommodating the iron core is formed between the upper and lower iron core sleeves. After the upper support, the lower support, and multiple iron cores are assembled, the upper and lower iron core sleeves cover the outside of the iron cores. When the winding is wound on the outside of the upper and lower iron core sleeves, the upper and lower iron core sleeves isolate the winding from the iron core, eliminating the need for rubber coating on the iron core. This simplifies the manufacturing process and saves costs. Furthermore, the winding in this utility model uses an outer winding method, which simplifies the winding process and improves production efficiency. Attached Figure Description

[0022] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0023] This utility model discloses a novel high-speed motor, combined with Figures 1 to 5 As shown, it includes a sleeve 1, a stator assembly 2 fixed inside the sleeve 1, a rotor assembly 3 passing through the stator assembly 2, and the stator assembly 2 including an upper support 20 of insulating material, a lower support 21 of insulating material, a plurality of iron cores 22 evenly distributed along the circumference, and a plurality of windings corresponding one-to-one with the iron cores 22. The upper support 20 includes a plurality of downwardly extending upper iron core sleeves 200, and the lower support 21 includes a plurality of upwardly extending lower iron core sleeves 210. The upper iron core sleeves 200 and the lower iron core sleeves 210 are connected vertically. The upper and lower ends of the iron cores 22 are respectively inserted into the upper iron core sleeves 200 and the lower iron core sleeves 210, and the windings are wound around the outside of the upper iron core sleeves 200 and the lower iron core sleeves 210.

[0024] In the above structure, the sleeve 1 serves as a protective shell for and fixes the stator assembly 2. The rotor assembly 3 is rotatably disposed inside the stator assembly 2. The upper support 20 and the lower support 21 in the stator assembly 2 are aligned and spliced ​​vertically. A cavity for securing and accommodating the iron core 22 is formed between the upper core sleeve 200 and the lower core sleeve 210. After the upper support 20, the lower support 21, and multiple iron cores 22 are assembled, the upper core sleeve 200 and the lower core sleeve 210 cover the outside of the iron core 22. When the winding... When the winding is wound on the outside of the upper sleeve 200 and the lower sleeve 210 of the iron core, the upper sleeve 200 and the lower sleeve 210 of the iron core act as a barrier between the winding and the iron core 22, eliminating the need for rubber coating of the iron core 22. This not only simplifies the manufacturing process but also saves costs. Furthermore, as a significant improvement of this invention, the winding adopts an outside winding structure. Compared with the prior art of winding on the inside of the stator, this invention is less restricted by the winding space, thus simplifying the winding process and significantly improving production efficiency.

[0025] In this embodiment, please refer to Figures 3 to 5The upper support 20 includes an upper cavity 201, and the lower support 21 includes a lower cavity 211. The upper cavity 201 and the lower cavity 211 are vertically aligned and interconnected. The rotor assembly 3 passes through the upper cavity 201 and the lower cavity 211. The upper cavity 201 and the lower cavity 211, being vertically connected, form a cylindrical cavity, within which the rotor assembly 3 is rotatably accommodated.

[0026] In order to wind the winding more tightly and reliably, in this embodiment, the core 22 is an "I"-shaped core including an outer extension 220 and an inner extension 221.

[0027] Accordingly, in this embodiment, the upper sleeve 200 of the iron core includes an upper slot 202 with an "I"-shaped cross-section, and the lower sleeve 210 of the iron core includes a lower slot 212 with an "I"-shaped cross-section. The upper and lower ends of the iron core 22 are respectively disposed in the upper slot 202 and the lower slot 212. The "I"-shaped upper slot 202 and the lower slot 212 can more tightly fit the iron core 22, thereby achieving a good covering effect.

[0028] In a preferred embodiment, the outer side of the upper slot 202 has an upper opening 205, and the outer side of the lower slot 212 has a lower opening 215. The outer surface of the outer extension 220 is exposed within the upper opening 205 and the lower opening 215. Since the outer side of the outer extension 220 is exposed, compared to a structure that completely covers the iron core 22, this embodiment reduces the damping during the insertion of the iron core 22 by providing the upper opening 205 and the lower opening 215, facilitating the insertion of the iron core 22 into the upper slot 202 and the lower slot 212, and significantly improving assembly efficiency and quality.

[0029] In order to limit and secure the iron core 22 at both ends, in this embodiment, an upper cover 203 is formed at the upper end of the upper sleeve 200 of the iron core, and a lower cover 213 is formed at the lower end of the lower sleeve 210 of the iron core. The iron core 22 is clamped between the upper cover 203 and the lower cover 213.

[0030] In this embodiment, the upper and lower supports also have a limiting function for the winding. Specifically, the upper end of the upper support 20 has a plurality of upper limit posts 204 for limiting the winding, and the lower end of the lower support 21 has a plurality of lower limit posts 214 for limiting the winding.

[0031] The high-speed motor in this embodiment can be applied to a hair dryer or a high-speed fan. For details, please refer to [link / reference needed]. Figure 1 , Figure 2 and Figure 6In this embodiment, a housing 10 is provided on the outer side of the sleeve 1, and an air guide cavity 11 is formed between the housing 10 and the sleeve 1.

[0032] Furthermore, a spiral air guide plate 12 is provided inside the air guide cavity 11. A fan blade 4 is connected to the end of the rotor assembly 3.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
